Sony MDR-NC6 Headphones

Pros: Great sound, nice bass and treble, power amplification, one small AAA battery, low-frequency noise cancelling works well

Cons: I didn't find anything I don't like. Noise-cancelling could be better, but still it rocks, and it's good for money and portability.

Summary: I bought these in Europe, for whopping 89 EUR, but still I think it's nice package for money. Noise-cancelling, other reviews underrated works well, but it is stated in specs it works only between 20 and 1500 Hz. I.e. it does not cancell voice or music, but does cancell well noise of transport, cars, plane engines, and even computer fan noise! Sound is very well. They are very comroftable and light, cord is long enough to make to belt or backpack where they player is. Another great feature - they use only one small AAA battery that lasts for about 30 hours in my case, just don't buy cheapy ones! Nice feature is power amplification, they adjust level of sound to the level of surrounding sound, so is noisy environment they sounds lauder. Great thing! And you can turn it off whenever you need - they will play as usual passive phones. And no additional module for NC-feature and batteries!

I use they with my notebook and also with my Sony Ericsson P910i smartphone, which I use as mp3 player too. Just get a 2.5mm to 3.5mm converter! Great phones, great deal! I would recommend it to anyone who are travelling a lot and work in no very quiet envoronment and loves to walk too, but not to listen street noise.
