I'm very satisfied with the sound, really good bass and a great surround sound. The sounds around are almost not heard, do not know if this is due to the Noise Reduction, or mind that the plugs suck downright ear. However, it arises in the ear a fairly strong negative pressure which is really nasty and I can only avoid so if I only lightly on the ear Place the headset, however, resulting in a worse sound to follow. What especially bothers me the unavoidable noise is generated when the cable. Pushes for example to the shirt collar and are forwarded directly to your ear. Even if I do not breathe and try absolutely not to move, I keep getting the sounds.
I'll return the headphones again probably. Too bad, because look and sound have really really really liked me, and it is also not so that the deficiencies described would be a general problem of Inear headphones, all that I have owned previously there were these problems not or only to a much lesser extent.
