Sony MDR-NC500, noise-cancelling headphones

For the frequent traveller, noise-cancellation headphones are an essential item. Noise-cancelling technology has come a long way. The essence of the technology is to create a sound wave that emits a sound with the same amplitude but with an inverted phase, also called antinoise. The dynamism of the outside environment presents obvious complications to the technology. There are also the consideration of other factors - comfort, build quality, and portability. The team over at Gizmodo did testing on various headphones to save some time for the consumer.

Coming in second place are the Sony MDR-NC500 headphones, which was the lightest of the bunch at 6.2 ounces. The sound is described as being balanced and even, capturing subtle details. The noise-cancelling feature worked well in most environments but was enough to overcome the sounds of an approaching train. Purchase for $400.
