Like the sound quality. The noise isolating is good, not great, but I wear them out walking in a rural area and need to hear cars, wild bears--just kidding. The regular ear tips didn't fit, but the foam ones work great, they stay put very well. Got these specifically because of the mic to use with my smartphone. Mic quality is only fair for the person on the other end of the call, even in the quiet indoors. For the price, these really should have volume control on the cord, also an auto redial function on... more info
May have quality issue:
I purchase mine 3 months ago, now the right ear does not working anymore. It looks like connection issue, when I touch the 3.5mm jack on the line the sound may on and off.
Broke easily and poor bass response:
These earphones sound excellent for vocals or terble-heavy music but they are terrible for anything with bass. If you like electronic music, hip-hop or anything with a lot of bass you will be disappointed. The microphone button stopped working within a few months and now the right earphone doesn't have any sound at all. I was pretty careful with these and always kept them in the hard plastic case. For the premium price I would expect better.
Ultimate Ears:
They are great headphones they sound great the only thing they lack is volume control.
