Articles: Best Headphones

Sound cancelling headphones appeared on the market a while ago. Several individuals use them on airlines to cover the sound of the aircraft. The first high quality sound cancelling headphones were developed by Amar Bose, CEO of Bose Technology. He realised that the standard head phones were unpleasant and presented some problems. In the 80s, Bose Technology was the fisrt company to release this technology to the public. The question is, how do they work and what makes high quality sound cancelling headphones?

The technology is based on inverting the noise around you to cancel out what you are hearing outside the head phones. It does this by a microphone picking up the sounds around you. They record these sounds and invert them and that inverted sound being the opposite of the sound outside effectively cancels it out. This technology works best for a constant sound such as an airplane engine or an air conditioning unit. They are less efficient on quickly changing noises such as speech as the sound waves change quickly and the inverting technology, working in real time; struggle to keep up with the changes.

To allow this technology to work, a battery power source is needed. In some models the battery is housed with the cables which can make it fairly inconvenient. More technology is moving to being housed in the earphone itself eliminating extra bulk. Some headphone models can continue to work as head phones even if the battery has run out, the noise cancellation technology just doesn't operate in these conditions.

There are two main types of sound cancelling headphones, the around ear and the over ear versions. The around ear tend to eliminate more sound as they work on an ear muff principle, passively reducing sound plus the noise canceling technology. Cushioning helps add comfort to the ears, but a number of people find them sweaty when used for longer periods of time.

Sound cancelling headphones that are worn on the ear simply rest on the ear surface and tend to be lighter. As a result they remove less outside sound but there is much more air flow. These are effective to cancel out background noise that is not too loud.

On feature to watch out for when evaluating models is whether the cable can be detached. Some individuals like to use them without listening to music. They just want the constant noise around them to disappear. This is helpful when you are concerned with guarding against loud noises such as during a flight or while operating your lawn mower or other power equipment.

Most individuals who use sound cancelling headphones tend to travel with them. The final accessory you should look at is the carry case that is provided. Soft cases are easier to fit into odd spots in your luggage or hand bag, but they do not provide the level of protection a hard case will.. .
