For those that are "BASS" fiends, then go don't look to these. Anybody else, read on. These are what I would deem a neutral headphone. There is Bass, but it is not the over-riding factor here. I like my music to sound like it was meant from the recording studio, and thats where these are ticking the boxes for me. They are well built, study, and ooze quality. The are very comfortable, albeit a bit big. But that size is from the 50mm drivers, so they will be bigger than those with 40mm drivers. The noise-cancelling works well. Having been tested in an office with a 4kW portable airconditioning unit located not 3m behind, they reduced the noise a lot, and it also meant that the music didn't need to be turned up to hear it. All in all I am very satisfied with my purchase.
