The sound quality is great when attached to my phone. Haven't listened on my laptop yet, but I doubt there's much difference. The battery life surprised the Hell out of me. Passed out for 8 hours with both firmly stuck in my ears still, and the music still playing.
The sensitivity of the buttons is a small issue, but I'll get it situated eventually. Not such a major deal that it would make me stop using them for a reason so idiotic.
