enclosed headphones

Noise cancellation is adequate considering the price.

Positives:
Handy retractable cord
Decent battery life
Comfortable

Negatives
Noise cancellation uneven between earcups

This is the second pair of these headphones I have tried. I returned the first pair because it seemed as though the cancellation was not equal on the left side. I even flipped the phones around and sure enough, one side sounded different. My second pair behaved in the same way and I concluded that the microphone on the top of the earcup must have been obstructed by the headband.

Overall, a good entry level setup however my next purchase will be the Sennheiser PXC 250. They offer better cancellation abilities and music reproduction. Or, if you really wish to go all out, there are the Bose. . .

I bought these to use with my Ipod, especially on long haul flights. They fold down to a compact size so are excellent for travel. Sound quality is excellent when listening to music. The full shell earphone is comfortable and the noise cancelling function cuts out a lot of low frequency sound. Priced in the middle of the range I think these are great value.
