I have an LG Muziq, that I like for the most part. I have gone through more headphones then I can count - at least 3 pairs of the expensive body glove sports, a few assorted other pairs, and have already gone through 3 of these Jabras.As far as I can tell, there isn't a single durable stereo headphone w. microphone set that works for mp3-playing phones. I have done tons of research, and have just found that EVERY thing out there that can handle stereo sound as well as let you talk on the phone, have a life of about 3 months tops. I don't know if its that I'm extra rough on them, but without fail, I will lose all sound in one of the headphones in about that time.That being said, these things are pretty decent for what they cost. The sound isn't especially good (the body glove ones sounded great) but its there, and they do curve around your ears so they won't fall out (like if you ride your bike). Personally, I wish there was a decent set of headphones out there for music phones, but since I haven't found anything even remotely durable, I'll probably keep buying these things.
