The best thing about the Jabra line is that their earpieces STAY IN PLACE so much better than the clip-over-your-ear style headsets or plain earbuds. This product is no exception, and it's perfectly comfortable.I was, however, expecting somewhat better voice transmission quality (I tested it by calling my own voice mail and having a friend call me using my own cell phone). It's adequate, but somewhat muffled. I've had clearer voice transmission from my end on a Plantronics headset that cost about $25.Since I got it for $10 and no shipping on clearance, I have no complaints - the mouthpiece is nice and small and so it's easy to stuff the whole thing in a pocket.
