Noise Cancellation Headphones - New Technology Emerges

It can really be a pain when you are trying to listen to music on headphones and you can hear constant background noise. If you commute to work, this takes many forms, the noise of traffic, the noise of the train, the noise of passengers near you yelling into their cell phones at 6:00AM, you get the idea. At home, this noise can be lawn mowers, crying babies, yelling children, air conditioners, fans, someone else watching television, etc. The sources of noise are pretty much endless. Welcome to the modern world. To address our ever increasingly noisy world, noise cancellation headphones were invented. Now all we have to do is flick a switch on the headphones and suddenly all goes quiet. Now we can listen to our favorite music unaffected by extraneous noises.

That is the theory, the real world does not always follow suit. There are good noise cancellation headphones and bad ones. The bad ones sound terrible and only mute the outside noise a little and eat up batteries. To be successful at canceling noise, everything must be in order. The lower the quality on any one component, the less effective the noise reduction will be. So how do they work? Basically the headset has a small circuit inside it that samples the outside noise. It then creates the exact opposite noise and plays it through the headphones along with the music. The noise from the outside plus the sound injected from the noise canceling circuit will cancel each other out at your ear resulting in music without the noise. How successful this is in practice varies wildly with different headsets. Another point worth mentioning is that high price doesn't always mean better performance. Some very high priced headphones out there are simply terrible at noise reduction. You really have to put a set on and try them out before buying. This task is best done in a store, not trying out and sending back every headset in a catalog online.

Last, but certainly not least, when evaluating noise cancellation headphones, make note of the estimated battery life. If you aren't getting at least 20 hours or so on a single set of batteries, you are going to need a lot of batteries. If the best set of headphones is a battery cruncher, though, I guess it's time to get rechargeable batteries.

 Best Value:  Goldring NS-100

Approaching the PXC450s for isolation and performance but half the cost!  They don't get too sweaty during a long listening session.  When using they are impressively musical, you will get a sweet but powerful sound.  They are termed 'an absolute steal at the price'.

Best for Style:  Beats by Dr Dre

The Beats - developed by Monster with the aid of NWA's most famous graduate - not cheap.  But these Apple-Store-exclusive headphones are excellent.  They are beautifully finished and very comfortable.  Their noise-cancellation circuitry is formidably effective, although they do allow more sound out to the outside world than some rivals.  Most cruically, though, they sound absolutely thrilling, with a punchy, deep sound, ample attach and plenty of detail.
