Description of use – Very easy to pair. I used them to listen to music while working on PC. Good Bass level. I had the volume 3/4 up and I was told by nearby users they could not hear my music, although, I could hear it very well. Headphones have In-line remote to control playing of music (play/pause) and also volume up and down. It is best to memorize which button does what and simply reach up and press the button vs looking down at the button to which you are exactly pressing.
