I've been using these headphones for two months now and they are excellent .. great quality at a convenient price .. comfortable on ears and head .. great flexibility.. the bass is perfect after you adjust the equalizer level on your music player. I use them on my galaxy note 3 the play/pause and answer/reject call button works perfectly, but volume up and volume down button don't work, maybe because i bought the ipod ipad iphone edition. You all should pay attention to that. It is just what I expected from an excellent headphones.
