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.

Do not use for music AS or A Levels, avoid using them for anything like a focusrite as you have to keep the little button held down in order to hear the full audio. For phones they work well but they aren't the best.

I used these headphones last week on a flight to USA and they worked really well and cut out the noise of the plane. I listened to some music and watched a pre recorded programme on my mobile and it was all good. Good value for the price.
