The noise cancelling was excellent, but the bass was +5db overblown, boomy and drowned out most of the mids, the treble was dark to hide the NC hiss Had pretty much the exact same experience with some noise-cancelling in-ear pair of Bose. I was actually amazed at how good the noise cancelling was, but sound reproduction even in absence of any outside noise was very sub-par. Now I can't imagine the engineers didn't measure this thing, so I'm assuming it was done on purpose, maybe aimed for pop music or so?
