^ Thanks for your feedback. Most owners seem to complain of the M2 hiss. Many of them on these boards. One person even said, "I can't even hear the hiss when the music is playing!" Seemingly happy that was such a good thing. I'm interested if users hear a hiss with nothing playing. Unless they fixed it, I'll bet you will also hear it sans music. Again, can you tell me of the NC in comparison to the D'Techs. How much better is it? As a side note, I'm concerned that the M2s might have more bass than I would like based on your comments. Most people like more bass than I do.
