First of all, be careful of fakes that sell for under $30. The package will look similar, but build and sound quality aren't even close. Luckily, it was a gift and I eventually lost it, which led me to this replacement which is the real deal. The real one is much better all around in terms of sound and build. However, it's still lacking in a couple of areas. Sound is good, but folks on the receiving end can still tell that I'm on an earpiece. They'll tell me that I sound like I'm in a big room. It could be worse, at least they can hear me clearly. The other bigger issue is the fit. It's comfortable enough in that it doesn't hurt after a while like some other earpieces, but that's because it's too loose. Don't turn your head too fast or brush up against something, because it'll fall out. As a matter of fact, that's how I lost the fake one. I've tried the other sized sleeves, but they all eventually loosen in your ear. Bottom line, not a bad earpiece, but not meant to be worn for long periods of time.
