I've been using these headphones for about 6 months now, primarily for work purposes and they have been absolutely amazing. Very easy to use controls, good volume and clarity (on both ends). My work deals with people that have hearing loss and have never been told I'm hard to understand using them. Audio quality for music playback is very good as well. I've also bumped into a few others with these headphones and they all have nothing but good things to say about them.
