Review title: Sound is just OK, but they do the job
Product review: I use these most of the day in a noisy office. The noise canceling does a good job on background hum and even on voices, which sound tinny and distant. I find they are comfortable for long periods of time.The sound is OK, if the NC on. Kind of heavy on the bass, while the highs sound faint and a bit strange to me. They don't compare to my Audio-techinca M30's at home. But still I use and prefer the NC set at work. Now I don't have to have the music on all day, and the volume can be lower when it is on.The 'heavy duty' (non-alkaline) batteries that came with the headphones lasted about 20 hrs. But alkalines and NiMH are much better and last the work week, plus.
