A wireless computer headset is used in the telecommunication systems to transfer information without the use of wires. It can be used both for long or short distant communication.

They also use electromagnetic waves to carry signal of the whole communication path.

Below are some of the most commonly examples which can be used in wireless computer headset:-

o LMR and SMR which are used by business, industrial and public safety people.
o Consumer two way radios
o Marine VHF radios
o Cellular telephone for both portable and mobile computer headset.
o GPS which is normally used by motor vehicle drivers, aircraft pilots and ship captain to guild them on the location there are in.
o Computer accessories such as keyboard, mouse and printers.
o Cordless telephones
o Satellite television
o Wireless gaming

All this examples are used in wireless computer headset within seconds while using the Wifi devices by connecting to the laptop which is easy to carry from one point to another. This technology has justified the use of wireless computer headset such as:-

o Distance of cabling the normal cables.
o To avoid structures such as EMI or RFI
o It provides communication incase of normal network blackouts.
o To provide temporary workstations
o To connect mobile or networks remotely

Most people have been confusing the term wireless and cordless. Cordless are cables devices that operate from a power socket from the main power supply.

A wireless operation was first invented by Jagadish Chandra Bose with the first detection device, electromagnetic wave and biophysics in the field.

Eight years later David E Hughes introduced morse code with a transmission called clockwork transmitter and in 1885 T.A. Edison invented a magnet vibrator which was used to signor the Lehigh valley railway and in 1888 he invented a wireless patent.

In the same year Heinrich Rudolf Hertz introduced the theory of electromagnetic wave which had early on been researched by James Clerk Maxwell and Michael Faraday. Rudolf demonstrated that electromagnetic waves could be transmitted through straight lines and were able to receive.

Later on his experiment was borrowed by Hertz with the practical application of the wireless communication with the remote control technology been improved by Nikola Tesla.

Wireless computer headsets have become so popular in today's world as it is less expensive. This new technology has found customers been charged a very minimum service charge and others been charged for free.

Do you often feel that you're going to go deaf sooner than later because you blast your headphones on the top volume peak possible? Wait, you didn't hear me? Turn your volume down some. I said, if you feel that you're going to go deaf because of your loud volume, you probably are! Just kidding, but you get my drift. People are used to having to turn the volume up way too high in order to get everything out of their favorite song, from the high kicks to the deep rifts. If you are a victim of this practice and wish that you could find a happy medium between turning the volume down some and hearing every element in your favorite song, you might have found your answer with noise cancelling headphones.

What are Noise Cancelling Headphones?

Noise cancelling headphones fit into the new world of technology as a new way to listen to and truly enjoy the quality of music coming from you music source. The new technology has taken the world by storm, giving many people the opportunity to listen to their music without having to turn it all the way up in order to hear all of the subtleties that make it great.

The way they are able to create a crystal clear sound without you having to turn them up is by reducing the ambient (or acoustic) noise in the headset by the speakers. They placed a microphone near the ear that creates a sound wave called antinoise. The sound wave is said to have the opposite polarity of the sound wave that arrives as the microphone. This means, when they meet, they cancel other out; this is called phase cancellation. Once phase cancellation occurs, a new sound wave is produced called destructive interference. The original sound wave is then placed a higher volume than the new sound wave, which eliminates unwanted noise. The end result is a crisp quality of music that allows you to hear every aspect of sound placed in the song.

Noise cancelling headphones have become so popular than many are getting in on the action by creating unique styles, as well as making them available for more devices. So now, you can find these quality headphones at varying price ranges, in over-the-ear, on-the-ear, or even in-the-ear styles, and for everything from your stereo or computer to your handheld musical device.

Bluetooth

I'm sure by now you've heard about Bluetooth technology. You've probably seen the Bluetooth earpiece attached to someone's ear as they've walked down the street looking as though they're talking to themselves. The earpiece, however, is one of the many innovations that have come from the company that specializes in wireless, hands-free technology. In addition to earpieces for your cell phone, they create everything from wireless GPS systems that communicate to your laptop, technology that allows your computer and printer to read pictures from your cell phone, and even blood pressure monitors that can communicate your blood pressure readings to your doctor automatically.

One of their other innovations is the wireless headphone that communicates directly to your iPod, MP3 player or even home stereo through an adapter, or directly if the device is Bluetooth-enabled. And now, many stereo manufacturers are creating Bluetooth-enabled, noise cancelling headphones. So in addition to being able to wear your headphones while moving around your home independent of the device you are listening to, you can enjoy the great quality of noise cancellation too!

For iPods and MP3 Players

The good news is that you can find great noise cancelling headphones that will work well with your iPod or MP3 player. In addition to being able to find Bluetooth-enabled, wireless headphones, you can now get some that even work to create the crystal-clear sound you want straight from your handheld device. So now, if you want to travel with your iPod but don't like the sound quality coming from your complimentary earbuds, you can use your new headset with noise cancellation technology to truly enjoy your trip with the music you love.

Who Offers the Good Ones?

Of course, like everything else, once manufacturers see a good product being sold on the market, they make a point to get in on the action. Unfortunately, this practice may not work as a benefit to you because you may find noise cancellation packaging without the quality to go with it. So to help you out, I have listed a few products on the market that are said to be creating the sound quality they advertise.

Bose Quiet Comfort 2 - Apparently these noise cancelling headphones are all the rage in airline magazines because they provide so much of a distraction to those wanting to avoid the obnoxious sounds of jet engines and babies crying while in mid-flight. They are said to be one of the best headsets on the market (and for the 0 price tag, they darn well better be!). Reviewers say that these incredible headphones block out noise even if music is turned off, and when you do turn it on, the crystal-clear quality will suffer absolutely no interruptions.

Sony MDR-NC33 - These headphones are seen as a jewel among reviewers because they provide great cancellation quality in a small, lightweight package. They are lightweight because they come in the form of earbuds. These great phones are said to have great bass quality, a nice high-frequency clarity and, of course, the absence of ambient sound. One of the downfalls of them, however, is that they are said to have a little hiss, so for the 0 price tag, it is my suggestion that you check them out at your local electronics store before committing to a purchase.

The best way to learn more about noise cancelling headphones is to do your research. Because the good ones tend to be in the pricier range, you want to make sure you get exactly what you desire for the price you're paying. While I know the Internet is a great source for finding products on sale, I highly recommend you test some noise cancelling headphones out in person before buying them online. That way you won't be disappointed when you still have to turn the volume all the way up to hear the sound quality you desire.
