Summary: Okay, so like the other reviews, you are taking a risk. I had ordered a pair last week, but when i received it, the mic wouldn't stay put and my left ear piece wasn't working. BUT!!!! patience is a virtue! I patiently filled out the defects report on amazon's website, and they sent me another headset for free next day shipping!!! And it even came on Sunday to my surprise! So.. I have used it non stop. I have huge ears and it still fits comfortable.
