I bought 2 of these...one for me and one for my partner. Unfortunately for me, I paid retail at BestBuy, but oh well. It stays on/in my ear pretty well. The different size ear loops have to be tried out to get the best fit. The sound quality is great in and out. Sometimes my phone answers and the jawbone doesn't  but I'm not sure if that's a problem with the phone or jawbone. Time will tell...
