Audio-Technica ATH-M50x with a set of memory foam ear pads (the stock ones are uncomfortable). Great sound quality (bass is _slightly_ exaggerated, but it works for the music I listen to), extremely comfortable (I can wear them 12 hours plus most days and barely notice I have them on), and reasonable noise attenuation. Not noise cancelling, but with them on and any sort of music I rarely notice anything except loud background noise. Only issue I've had is that a tab that holds the headphone in place has broken twice, though Amazon replaced it both times under warranty and I haven't heard of this being a widespread issue, so YMMV (this is over about 5 years of heavy usage, and one pair was an Amazon Warehouse pair to begin with - current pair is about a year old and showing no signs of the issue).
