but I didnt want to buy headphones that I may or may not hate the fit of. No gap in rear waistNo aggravation from the zipper or button. To make things worst the material REALLY attracts dust and lint. Even during moderate exercise they?ve never come off and don?t feel like they will. In early tests, the flip to mute mic works seamlessly and the listener on the other end of the computer will hear you clearly. Definitely Recommend Yes, you can turn them up and they can get quite loud when the music is playing, but they are lacking in the low and frequencies. It tends to tilt backwards from the weight which applies forward stress and pulls the tape off. The zipper on the back stays up and does not rub into your ankle. I been needing a replacement for my Sennheiser HD518 that I accidentally broken for a while, however, fair warning.
