Initially, I thought their sound/$ value was awesome, but their build quality is absolute shit. My girlfriend and I went through a combined 4 pair in about 9 months (with some time between purchases). To be clear, I'm a heavy user. I wear them at work, gym, and on the bike.
I'd only own them if they were going to stay exclusively paired to a home laptop or something else that doesn't travel. Then again, earbuds don't make much sense for such an application.
A little more money spent on comparable Westone or Shure models has always been a sound
investment...for me, at least. YMMV
