Earphones and headphones market – global industry analysis and opportunity assessment 2014 – 2020 scrutinized in new research

We have seen a huge demand for headset and headphones over the last few years, helped by the emergence of luxury brands like Dr Dre beats range. You can find the original article on this website.

The demand in the region is lead by the countries such as China, India, South Korea, and Japan. Latin America is also expected to experience significant growth of earphones and headphones market driven by growing number of portable devices in the region.

Portable music systems such as smartphones, tablets, and portable music players are experiencing significant growth in demand and this in turn is driving the growth of earphones and headphones market. The global market for headphones and earphones is anticipated to experience considerable growth over the coming years.

In the recent years, the technological advancements in headphones have led to minimization of the overall weight of the headphone. Additionally, sophisticated noise cancellation features in earphones and headphones have been aiding in the rising popularity of these devices.

Major technological developments in wireless such as Wi-Fi, Infrared (IR), SKAA and Bluetooth are expected to continue driving the growth of earphone and headphones market.

Shifting consumer trends toward the adoption of headphones/earphones during working out is also giving a push to the growth of this market. Moreover, companies are targeting youth through introduction of new and innovative features.

The increasing availability of low cost counterfeit products poses a significant challenge to the growth of earphones and headphones market.

In the Asian countries such as China, India, Taiwan and Indonesia, there is a significantly large unorganized market for earphones and headphones.

This unorganized market often sells counterfeit and low standard products at a significantly lower cost poses a serious challenge to the organized players in terms of revenue and demand. Addition of features such as voice recognition represents a significant future growth opportunity in this market.

Based on product types, the headphone and earphone market includes wireless speakers, wireless headphones, and microphones. The headphones can be further categorized into in-ear buds, gaming headphones, over-ear headphones, wireless headphones, and clip-on headphones.

North America has been the leading market for earphones and headphones owing to significantly large penetration of portable devices. Further, the region also has significant demand for high end earphone and headphone products leading to higher revenue generation.

Asia Pacific is anticipated to be the fastest growing market for earphones/headphones owing to boom in the portable/mobile devices market in the recent years. The region is experiencing rapid growth in demand for smartphones which is driven by increase in disposable income of a significantly large population.

Identify the features of two way communication

Here we Identify the features of two way communication using two way radio, A two way radio is basically a radio that can transmit and receive. Two way radios are simple, convenient and affordable way to stay in close contact with your colleagues, family and friends. Most companies use two way communication systems as a primary source of communication between their workers due to the ease, promptness and convenience offered by this communication system. The following are some of the key features of a two way radio system and their benefits;

900 MHz frequencies

It is essential to point out that radios that operate within this frequency are capable of effectively communicating both indoors and outdoors. This means that they can be used in factories and other workplaces as well as outside when camping or hiking. Most cordless phones also use this frequency. However, the best thing about two way radios that use the 90 MHz frequencies can be used by both individuals and businesses without a problem.

Adjustable gain

Most two way radios come with an adjustable gain feature. This feature allows the user to adjust the sensitivity of the radio’s microphone. This feature is also useful along with the hands free operation feature because it reduces the possibility of unintended noises triggering transmission. It also enhances the ability of the radio to pick up quite voices.

Auto channel change

This feature enables all radios within your group to change to a new channel. This helps in preventing interference from other devices. For you to use this feature, everyone in your group must have two radios that support this feature. In case one channel is not so clear you can simply change and use the channel with little or no interference.

Backlit display

Most two-way communication devices including radios have a digital LCD display feature that displays useful information for instance your current channel. This feature enables you to turn on a lighted display which makes it easier for you to read the information on the screen especially in dark or poorly lit areas.

Channels

A channel is a frequency on which two individuals using two way radios can communicate. Typically, there are 14 FRS channels as well as 15 GMRS channels. Two way radios that support both FRS (family radio service) and GMRS (general mobile radio service) have the capability of supporting up to 22 channels. This makes it easy for people to communicate with each other using these radios. However, to effectively communicate, all radios in the group should be set to the same channel.

Battery

Two way radios are mobile devices. This means that they are designed for you to move around with them. As a result of this, these radios operate on battery power. Most radios work with standard alkaline AAA or AA batteries. Other models include rechargeable batteries. For those models that come with rechargeable batteries, it is essential for you to always fully charge the batteries before using the radio for effective communication.

Call waiting feature

Just like the regular mobile telephones, two way communication radios also have call waiting feature. If you are already on a call, this feature allows you to receive a notification that someone is attempting to reach you. The latest models will give you an option of immediately accepting the new incoming call or simply reject the call and calling back thereafter.

Call tones

Call tones allows the user to alert the other radio users in the group that he or she wants to talk. It is similar to a telephone’s ringing that indicates that someone wants to talk or someone is calling. Most radios allow the user to select from a variety of call tones.

Intrinsically safe

Also known as IS, intrinsically feature is a protection feature or technique used for safe operation of electronic devices in explosive environments. This concept was solely developed for safety measures specifically operation of process control instrumentation in unsafe areas. This means that two way communication radios can be safely used in hazardous areas without the fear of exploding or causing harm to the user.

In summary, from the above features and benefits of two way communication radios it is clear to suggest that, these radios are convenient, affordable and safe modes of communication that can be used in workplaces as well as at home. They can also be used outdoors during camping, hiking or simply enjoying a shopping expedition in town.

How to be a better headphone listener

When you’re listening to speakers the sound comes from “over there,” but with headphones where is the sound? A lot depends on the recording and the headphones. With mono recordings the sound is centered inside your head, with stereo the sound picture is more complicated. Vocals, or any sound mixed to appear centered between the left and right channels, will be inside your head, like a mono recording. The sounds over to the left and right might come from next to your ears.

Listening over one of the better open-back full-size headphones, the sound might feel like it’s surrounding you. You’re in the middle of the sound field, or it might come from slightly above your head. The headphones melt away and you are one with the music. Sometimes when I’m watching a movie I forget the headphones. The sound isn’t over there, it’s all around me; I’m in the middle of a sound “bubble.”

I’m not suggesting that headphones can ever mimic what we hear from speakers. Headphones can’t do that, but the downside to speakers is they can never be heard directly; the speakers’ sound is combined with the room’s reflections, reverberations, and other forms of acoustic interference. With headphones the sound “couples” directly to your ears, so you have a far more intimate connection to the music.

With full-size over-the-ear headphones, the contours of your outer ears direct the sound to your inner ears in the same way sound is heard from speakers. In-ear headphones “bypass” the outer ear and produce a more direct connection to the recording. With purely acoustic music, the sound over headphones takes on what I call a microphone perspective, you hear what the mics “heard.”

That’s not the case with electronic music since no microphones were used to make the recording. Even so, I find lots of electronica sounds amazing, and some of the best albums were mixed to produce out-of-head stereo imaging. Listen for depth, does the sound seem very close to your ears or further away? Recordings vary a lot in their stereo imaging, but the more closely you listen, the more aware you will be of spatial cues in headphone listening. Try some of Brian Eno’s ambient albums like “On Land” and “Apollo” to hear what I’m talking about.

To get started, relax and focus on the sound. Your surroundings should be fairly quiet, close your eyes, and sink into the music. After a few minutes the separate left, center, right stereo perspectives should fall away, and your head will feel like it’s in the center of an expansive sound field.

Share your thoughts on spatial headphone listening below.

We found this excellent article here and as you can see it give us valuable information on why headphones aren’t better than speakers, but if you don’t want your neighbors complaining or your family moaning, then you’ll have to wait for the technology to come up with perfect acoustic sound.

In Your Dreams: Bloke Dreams About Winning The Lottery, Actually Manages It …But Then Has To Give Half Of It Away…

Back in 2012, Fatih Ozcan, a waiter working at the Kucukkoylu Turkish restaurant in York, apparently experienced a prophetic dream which involved him holding huge bundles of cash in both hands, whilst his boss, Hayati Kucokkoylu (either the restaurant is named after him or its an amazing coincidence) was standing in front of him.

Mr. Ozcan interpreted this dream as meaning that, if he played the lottery with his boss’ money, he’d win huge bundles of cash.

…Well, he was half right.

At work the next day, Mr. Ozcan pestered his boss to buy a few ‘Euromillions’ tickets, using money from the till. The boss eventually relented, suggested some numbers and gave him some cash.

…Amazingly, Ozcan later checked his ticket to find that he had won a Million quid.

When Fatih told Hayati of his fortunes, the boss decreed that all of the money was, in fact, his by right, as his money had paid for the majority of the tickets. Ozcan, for his part, was having none of it, and a major falling out occurred between the two men.

Eventually, the argument ended up going to court, where a judge (with apparently more sense than either man combined), decreed that the winnings should be shared 50/50 between the man that had supplied the ticket and the man that had paid for it.

Sounds fair, right? I mean both men still get a £500,000 payday out of it.

In summary, the waiter had the dream, stumped up a little cash and picked a few numbers. The restaurant manager donated the most cash (the princely sum of £9) and also picked a few numbers himself.

It really isn’t rocket science. 50/50 seems pretty fair to me…

Apparently that wasn’t the end of the debacle, though, as Kucukkoylu appealed the decision and took the issue to the London Civil Appeals Court, in the hopes of walking away with the full Million.

This month, after three years of legal wrangling, yet another judge told him to ‘bugger off and stop being so bloody greedy’ (albeit probably using more fancy language than that). The judge then declared that the fairest course of action was (you guessed it) to split the money 50/50, which pretty much any reasonable person would have already done anyway.

According to Kucukkoylu, he chose the numbers and paid for the ticket and thus, the money should rightly be his, however, without his employee having the dream in the first place, he never would have bought a ticket.

The really pathetic part of this story is that neither man appears to be happy with getting a £500,000 payday – and thus both saw fit to fight over it in court for three years, presumably spending loads on their legal fees.

…Seriously, where’s the logic?

Its hard to decide whether these men are simply greedy and stupid, or just stupid and greedy. Either way, it isn’t good.

As for the (presumably now fired) waiter – let’s just hope any dreams about seven fat customers devouring seven lean ones turn out to simply be a case of eating too much cheese before bed!

British Screen Icon Richard Attenborough Passes Away, Aged 90

British actor, director and screen legend Lord Richard Attenborough passed away last August, he was 90 years old.

The iconic performer, known for a plethora of memorable film roles over a career spanning an impressive six decades, leaves behind a majestic legacy. What follows is an overview of Attenborough’s film work, both as an actor and a director and, after that, a few words about his contributions outside of cinema.

Beginning his career in the 1940’s, the young actor started out in numerous stage plays before attending The Royal Academy of Dramatic Art (RADA), which he would later serve as president. His early film roles included the Noel Coward directed wartime film ‘In Which We Serve’ (1942), which starred John Mills, ‘A Matter of Life and Death’ starring David Niven (1946) and the original film version of ‘London Belongs To Me’ with Alastair Sim (1948).

Lord Attenborough’s big break came in 1947, when he starred as unscrupulous gang leader Pinkie Brown in the film adaptation of Graham Greene’s novel ‘Brighton Rock’ (which also stars future ‘Doctor Who’ actor William Hartnell). Attenborough’s portrayal was nothing short of mesmerizing in its coldness and cruelty and, by 1949, he was considered to be among the most popular British actors of the day.

Throughout the 1950’s, Attenborough starred in war films such as ‘Dunkirk’ – again with John Mills (1958) and comedies like ‘Private’s Progress’ (1956), he also dazzled as Stoker Snipe in the 1950 film adaptation of ‘Morning Departure’, a highly moving piece about a submarine crew stranded at the bottom of the sea, which also starred John Mills.

In 1960, Attenborough portrayed factory worker Tom Curtis in ‘The Angry Silence’, a British ‘kitchen sink’ movie that saw his character refuse to join his fellow workers on strike as himself and his family dealt with the consequences. He also appeared in the classic crime drama ‘The League of Gentleman’ in the same year.

In 1963, Attenborough starred in ‘The Great Escape’ playing Bartlett ‘Big X’ alongside an all-star cast that included Steve McQueen, James Garner, Donald Pleasence, Charles Bronson and James Coburn.

1965’s Oscar nominated ‘The Flight Of The Phoenix’ saw him playing alongside Hollywood screen legend James Stewart. In 1967, Attenborough portrayed Albert Blossom in the musical film ‘Doctor Dolittle’ and, in 1969, he directed his first feature, the musical ‘Oh, What A Lovely War!’

In 1971, Attenborough performed one of his most memorable roles as the serial killer John Christie, acting alongside John Hurt and Judy Geeson in ‘10 Rillington Place’. He was reluctant to take the part at first, but appears to have done so in order to take a stand against capital punishment.

In 1975, he starred alongside John Wayne in ‘Brannigan’. In 1977, he directed ‘A Bridge Too Far’, a war story that starred Sean Connery, Michael Caine, Gene Hackman, James Caan and Anthony Hopkins.

In 1981, Attenborough completed a true labour of love and his most noted work as a director, the epic biopic ‘Gandhi’, starring Ben Kingsley. The film earned Attenborough two Academy Awards, one for directing and one for producing. In 1987, he directed Denzel Washington in ‘Cry Freedom’, which celebrated the life of anti-Apartheid activist Steve Biko. He would next produce and direct a biopic in 1992, directing Robert Downey, Jr, Marissa Tomei, Dan Akroyd and Geraldine Chaplin in ‘Chaplin’, a film depicting the life of influential movie star Charlie Chaplin.

Attenborough’s two most famous late career roles occurred within one year of each other. In 1993, he portrayed impresario John Hammond in Steven Spielberg’s ‘Jurassic Park’ (a role he would reprise in the 1997 sequel ‘The Lost World: Jurassic Park’) and in 1994, he joyously appeared as Father Christmas in the re-make of ‘Miracle on 34th Street’, both roles won Attenborough critical acclaim, as well as an entire generation of new fans. In 1998, he appeared as Baron William Cecil in ‘Elizabeth’, an historical drama also starring Cate Blanchett, Christopher Eccleston and Geoffrey Rush, which focussed on the reign of Queen Elizabeth I.

Attenborough directed his last film, ‘Closing The Ring’ in 2007 and gave his final acting performance in 2004, lending his voice to the film ‘Tres En El Camino’.

Away from acting, Lord Attenborough was active in politics; he was appointed as a life peer (as Baron Attenborough) in 1993 and chose to sit on the Labour party benches at The House of Lords. He was a vocal opponent of South African apartheid and a lifelong advocate of racial equality. In 1983, he was awarded the Martin Luther King, Jr. Non-violence Peace Prize by the Martin Luther King, Jr. Centre For Non-violent Social Change.

A passionate advocate of education at all levels, Attenborough served as Chancellor of the University of Sussex for 10 years (from 1998 until 2008) and he was a patron of University College, Leicester, where his father had served as principal.

He also worked tirelessly on behalf of several charities, including The Muscular Dystrophy Campaign, The Richard Attenborough Fellowship Fund (which also aims to fund research into neuromuscular conditions) and UNICEF, for whom he served as Goodwill Ambassador and donated many of the proceeds from ‘Gandhi’ to. From ‘Gandhi’ alone, he raised in excess of a Million Dollars for the charity.

Lord Attenborough received a CBE (Commander of The British Empire) in 1967 and was fully knighted in 1976. From 1969 – 1982, Attenborough, a dedicated football fan, served as the director of Chelsea Football Club. Between 1993 and 2008, he was also the club’s Honorary Vice President.

Richard Attenborough’s career was truly groundbreaking in every sense of the word. He was unquestionably one of the greatest actors of all time as well as a man of moral courage and noble spirit. As an artist, philanthropist, educator and man of conscience, this world will be much poorer without him.

BIG Changes Announced By DC Comics…Again

When veteran comic book publisher DC Entertainment announced that it was ending its entire line of comic books and starting everything again at Issue 1, the fans went crazy.

Some comics had been running, there or thereabouts uninterrupted, for 700 issues or more – and now it seemed that it was all over. Still, in 2011, when DC announced this major upheaval, naming their initiative ‘The New 52’, the first few issues actually sold rather well.

DC had started out by promising a company-wide ‘reboot’ of all their characters/stories, but then baulked at using the term after fan outcry became too great. Instead, it became seen as a ‘soft reboot’, or a ‘revamp’, which left fans – and creators too, evidently – scratching their collective heads regarding which major storyline events had still happened in the new timeline and which hadn’t.

Many fans, for their part, were upset that Frank Miller David Mazzuccelli’s ‘Batman: Year One’ was no longer the Bat’s official origin story, replaced instead by the gruelling, overlong ‘Zero Year’. In fact, fans were further annoyed when other classic texts such as Alan Moore Brian Bolland’s ‘The Killing Joke’ and Jeph Loeb Tim Sale’s ‘The Long Halloween’ also departed from Bat-continuity.

Elsewhere in the DCU, Superman was no longer after Lois Lane, instead striking up a romance with Wonder Woman. Barbara Gordon, the original Batgirl – latterly the company’s only major disabled character as Oracle – was miraculously able to walk again and The Flash Mk III, AKA Wally West, was simply erased from continuity altogether.

As time went on, we learned that The Joker was probably immortal, that Dick Grayson gave up his crime fighting identity of Nightwing to become a spy, that Green Arrow was somehow a kid again and that Catwoman and Batman enjoyed regular ‘on the job’ sex. In costume.

Of course, there were good stories, too, but as far as many fans were concerned, the end result was, to borrow a line from Red Dwarf’s Kryten “garbled, confusing and quite frankly duller than an in-flight magazine produced by air Belgium”.

Now, just four years later, sales have apparently slumped again, so DC’s reaction has been to plan another, still more drastic, reboot of the company’s characters.

The starting gun will be a story called ‘Convergence’ and it is set to officially begin next month. After that, the company will take a two-month hiatus and return with a new and completely rebooted line. Again.

Well, you know what they say, if at first you don’t succeed…

DC has already teased a ‘new look’ for Superman and Wonder Woman, designs that, personally, I’m hoping are April fools’ jokes. Superman will now be fighting crime and injustice with a buzzcut hairdo and a jeans-and-t-shirt ensemble that makes him look like, to quote one commenter “a gym douche” and Wonder Woman now has a 90’s style armoured battlesuit.

By working within the continuity established by The New 52, but moving it to the ‘back burner’ as it were, DC Co-Publisher Dan DiDio hopes that “In this new era of storytelling, story will trump continuity as we continue to empower creators to tell the best stories in the industry.”

Launching 24 new number 1 issues in June (‘The Poor 24?’, ‘Less Is More, 24?’ – I’m just trying to come up with an angle for this), DC Entertainment is hoping to capture a funnier, sunnier feel with some of its characters. 25 successful series will be kept, but tweaked with new creative teams and whatnot.

Sadly, at least as far as online discussion is concerned, the overall feel is not one of ‘glorious new rebirth’ as much as it is ‘here we go again’. The image in the eyes of this long-time fan (and former ‘New 52’ apologist) is one of DC hitting the panic button in yet another sad attempt to appear ‘modern’ and ‘contemporary’ whilst actually revealing itself as stodgy and out of touch in the process.

Here’s Co-Publisher Jim Lee, usually one of the sharpest minds in comics, essentially blaming the audience for the failure of ‘The New 52’…

“It was really weird when we launched the New 52 — there were so many fans focused on, “What happened between the five years, when this character showed up, and this character” — it almost overshadowed what the original intent of it was, which was basically to put a fresh face on the universe, boldly go forward, tell new stories. This is an attempt to refocus the line, focus on story, focus on producing great stories that become canon, and letting the creators have some freedom to tell those stories, without necessarily being confined by the restriction of “continuity.”

Of course, comic book creators have been working with continuity, in one form or another, for 75 years or more, so it actually just seems to be the current crop (and thus, a tiny percentage overall) of creators who find it to be a “restriction”. But I digress, here’s more from DC’s Co-Publisher.

“I’ll just use one example — there was a tweet I saw, someone complaining about “Throne of Atlantis,” the DVD adaptation of the comic book. The complaint was, “Superman and Wonder Woman don’t breathe underwater. You failed.” Maybe the continuity proves that right, I don’t know — I’m pretty sure I’ve put Superman under water, and he was fine, and he’s been to outer space, same with Wonder Woman — when those things start overshadowing the story, and the emotional beats, I think there’s something wrong with what’s going on in the marketplace. That’s my perspective”.

One might argue that being DC’s Co-Publisher, it’s actually his job to know everything there is to know about Superman, including whether or not he can breathe underwater, but that’s really just the tip of the iceberg here.

Anyway, love the idea or hate it (and I think I’ve made my own feelings pretty clear on the subject), DC’s new line will be launching in June. Make of it what you will.

For many fans, (including myself) the reaction is not one of excitement and glee, but is, in fact, more akin to Seinfeld’s J. Peterman being confronted with ‘The Urban Sombrero’.

“The horror…The horror”

How Do Passive Noise Cancelling Headphones Work

It is quite unfortunate that for most music lovers, there is a myriad of ambient noises and sounds that can really interfere with the music coming from your earphones, Now, if you have ever once tried to listen to music on a bus, train or airplane, then you are intimately familiar with this problem. The engine’s roar and/or the incessant chatter from fellow passengers, make extremely hard to hear the sounds coming from your speakers, even if they are on or inside your ear. Fortunately, to combat this dilemma, innovators have come up with far more enjoyable way of listening to your music- Noise canceling headphones of which there are two types:

- the active- the passive types.

HOW PASSIVE NOISE CANCELLATION WORKS

The simplest type of noise cancellation is the passive noise reduction, sometimes called noise isolation. From a technical perspective, just about any kind of earphones are able to provide some degree of passive noise reduction (though some are designed for it more than others). This is mostly as a result of the materials used to make the headphones which block out particular sound waves, mostly those of a higher frequency. The absolute best type of passive noise canceling headphones are however the circum-aural types which are specifically engineered to maximize the amount of noise it filters. We will take a look at this some more in a bit. Essentially, where passive noise isolation, the head phones are so designed that they will fit snugly into or around each ear. This makes it significantly harder for noise to escape and bother others in your immediate environment, and it also prevents the noise in your environment from making it hard for you to listen to your music. Passive noise cancellation earphones tend to have very large ear pieces, with large pieces of foam wrapped around them. You need to squeeze the foam into your ear which them provides a perfect seal for the ear canal, or they fit just right around your ear.

All this is saying that passive noise cancelling earphones in essence imitate what happens when you choose to cover your ears with your hands or put some ear plugs in. The excess padding is always done with materials that naturally act as sound barriers- fitting into your ear and sealing off the ambient noise.

Supra-aural headphones, which are earphones placed over and around the ear, instead of in or around it, are probably the very worst at any form of sound cancellation. They tend to be low density, small and very light, as such there is really not much padding to block and outside sound or ambient noise from entering the ear. Furthermore, because they are only placed on the ear, there is a great deal of space for any external noise to travel around them and into the ear canal. It is on very rare occasions that you actually find a top quality supra-aural earphone, because they are simply unable to provide the kind of noise cancellation that circumaural or in ear headphones provide. Supra-aural earphones are lightly manufactured and as such are usually marketed for customers who are not particularly focused on headphone quality, but mostly looking for basic functionality.

Take for instance, most desktop or video game headsets tend to be supra-aural. They are mostly preferred because they are light and as such are suitable for the long, extended hours they will be used. Additionally, in cases like these audio quality is not of great importance since it they are mostly used for spoken communication, where clarity is the focus and nothing else really matters.

When it comes to passive noise cancelling headphones, circumaural or around the ear headphones provide a significantly better noise cancellation quality. They are bigger in size and as such they include more noise reduction material. This in turn creates a far better buffer against outside noise- think beats headphones. Essentially this means that they are heavily packed with layers of high top quality high density foam,, or some other sound absorbing material. Admittedly, this then makes them a bit heavier than the average headphones, but since they completely block the ear off, they keep out up to 95% of outside noise. Well, this is assuming that the circumaural earphones you choose, fit your ears snugly. If they are either poorly designed or not the perfect fit then ambient noise will still be able to make its way in.

Do all Motorola Walkie Talkies work with each other?

One of the most commonly used communication devices is the walkie-talkie. Its use is not only for business operations, but it is also highly loved by kids and parents give them as presents due to their cheap nature. Someone would never require getting in a physical store to purchase a Motorola walkie-talkie as there are many online stores selling them.

Where to use a Motorola walkie-talkie

• Use walk-talkie for some outdoor activities like climbing, snowboarding, and ski-ing

Some of the outdoor activities require you to be out in areas where there is no mobile network coverage. Although some of the areas may have support for mobile network, using a phone may turn to be more expensive. Moreover, mobile phones operation in such areas may be expensive and many people would never use them if given a chance. A Motorola radio can be useful in such areas as it provides a way for keeping in touch with your friends or relatives.

• Use the walkie-talkies for communication in a restaurant, clubs, bars and even pubs

Clubs, restaurants or bars having large customer circulation may highly require the use of the device to pass information within the premises to save time. Using a mobile phone in such a place can be expensive and may highly increase the expenses therefore reducing the profit margin. Mostly they can be essential for security purposes and the door supervisors can use them in their work. The other staff may also find them useful in their operation as movements will be highly reduced.

• Make use of them in monitoring your baby

Monitoring your baby while in holiday at times may turn to be hectic. Purchasing a pair of Motorola radio can highly assist in this monitoring. You may use them as long range baby listeners as they can cover a wider range than you may ever expect.

• Make use of Motorola radios in schools and colleges

There are many communication issues that usually surround a school or a college campus. At times you may find the staff members moving for long distances which may make the task of tracking them when needed hard. Also some schools or colleges may not have their staff members being desk based hence they may not be having a telephone. Providing every member of staff with a Motorola radio can highly solve some of the tracking challenges.

Do all Motorola walkie-talkies work with each other?

Yes, all Motorola radios will work with each other. All the models use GRMS/FRS frequencies, which allow their compatibility. To enable the compatibility, you only need to tune your radio to the same channel as your colleague and you will communicate effectively.

The family radio system (FRS) has been in use in the United States since 1996 and it uses channels in the ultra high frequency (UHF), which protect it from interference from citizen band or other frequencies found in baby monitors. FRS systems use the frequency modulation (FM) and therefore has wide range coverage compared to other systems.

Advantages of using a Motorola radio as a communication device

1. It is almost a no cost device of communicating to any person

After purchasing a communication radio you will not be liable for license charges, monthly charges or even contract charges as its use is absolutely free. The only cost you can expect is the recharging of the battery.

2. It’s the best communication device for people working for emergency situations

People offering emergency services like a building collapse or fire fighting highly require the device in their communication.

3. They are highly convenient

If you need to keep in touch with a person who lives near you, a walkie-talkie can serve you better compared to a mobile phone. You will never need to pay any charges and therefore you can communicate with your colleague any time you wish and also you are the only one who can end your talk.

4. They come in a variety of forms

When purchasing the device you are required to select from the many shapes, forms, types and even color that suits your taste. Manufacturers are always aware that kids will like their devices to be different from those of their friends and they will always design them in many ways. Walkie-talkies will allow instant connection at any time

How Does My Mobile Phone Work?

A mobile phone is a type of transceiver, meaning that it can both transmit and receive radio waves. The clever bit is that, unlike other transceivers such as walkie-talkies, it can relay both signals simultaneously. A mobile phone achieves this by running two separate signals, one for transmitting and one for receiving, at the same time.

Aside from that, there really isn’t a huge amount of difference between a mobile phone and a walkie-talkie. Just like a walkie-talkie, once you talk into the speaker, your voice is converted to an electrical impulse and relayed, via electrons housed inside a small antenna, to the intended recipient. Then, just like with a walkie-talkie, those same electrical impulses are converted (via a reversal of the initial process) back into your voice. Mobiles, like walkie-talkies, have small, compact aerials and use relatively small amounts of power.

However, unlike walkie-talkies, mobile phones can communicate with one another over much vaster distances. How? Well, this is the REALLY clever bit. The cellular network divides up land into cells and each cell has its own phone mast. The phone mast boosts the phone’s signal, in essentially the same way a signal tower does for a radio network, except that they relay the signal from your phone to other cell towers, allowing the signal to carry across much further distances without significant degradation.

Of course, there are only so many available radio frequencies in any given area. Walkie-talkie users prevent the mass chaos that uncontrolled broadcasting/transmitting would no doubt cause by licensing and heavily policing radio usage (in fact, we covered this exact subject earlier in the month).

Imagine if emergency services were unable to use their radio frequencies! Awful. It is therefore very important that frequencies in use are policed and this is why you cannot buy radios with a power output stronger than 0.5 watts without a license.

However, mobile phones operate differently. Each mobile essentially re-uses its own frequency, in a similar way to a licensed radio frequency might. It is rare that all possible frequencies are in use at the same time, but it actually does happen (think: New Year’s Eve).

Introducing the Sensear Intrinsically Safe Double Protection Headset

Many of you might not heard of Sensear, they are making big strides in the headset industry, here is their latest offering.

Sensear, a global leader in developing and manufacturing best-in-class digital communication headsets, announced the release today of their new Intrinsically Safe Double Protection Headset (IS-SDP). Based on Sensear’s existing SM1xSR IS headset, and incorporating the double protection feature from Sensear’s current non-IS double protection headset; the new IS-SDP headset includes an improved boom microphone, and will interface with a variety of two-way radios both cabled and via Bluetooth for wireless operations.  Bluetooth can also be used with IS Smart phones and other IS Bluetooth devices.

The Sensear IS-SDP headset was developed from a marketplace need for a high performance intrinsically safe headset for extreme noise environments that require Class 1 Div 1 certification. Double hearing protection (both ear plugs and ear muffs) is often required when exposures may exceed 95 decibels (dBA) in many critical working areas. At the same time operators in these environments are required to use two-way radios to hear site communications and respond appropriately. Without the use of an appropriate intrinsically safe headset communications on site can potentially be very difficult.

The ear-plugs for the IS-SDP are hard wired to the headset allowing for dual protection, and communications to be directly understood by the operator. The IS-SDP’s 31 dB NRR combined with Sensear’s patented SENS™ technology allow operators to protect their hearing at a safe level of 82 dB, communicate effectively between co-workers via two-way radio and Bluetooth and maintain 360-degree awareness.

“We were excited about the development of the IS-SDP the early beginnings of Sensear grew from creating unique solutions for many industrial environments,” said Peter Larsson, CEO.  “The IS-SDP continues to show our commitment to developing practical, usable products that solve the communication challenges in heavy industry.”
