I bought this a few weeks ago and my conclusion is that the sound quality is petty good but the noise cancellation is a little redundant, its no different from when its switched off to when its switched on. I find that the headphones can be a little tight too, after about 40 mins my ears become sore and need a 10 min rest.

I bought this product to use when I travel on holiday, the headphones fold in was useful when carrying them in a bag, I use them with a small mp3 player and works well

Great sound, Easy to use (plug in and it works). Noise cancellation works with just a switch on and (so far) good battery life (1st set, 15 days at ~5hrs/day) 3 things to make better - 1... Blutooth (I believe a more expensive model does it but x3 price) 2... Why are there wires to both Ear's? Battery & NC Amp are wired inside headband, why not pass a single connection through as well ? 3... Wired connection needs also to be able to unplug from Headphones (3.5mm 4 contact jack L,R,Mic, earth) so able to use as Noise Cancellation alone.
