I've had these beauties a year now and they are still going strong. They work perfectly with my iPhone 5 and my ipad air . Superb quality and sound . I use them when jogging and they don't budge. I don't work for jaybird, but these are the only Bluetooth headsets on the market. forget the rest!
Just purchased a pair of these a couple of weeks ago and they are just great. They fit like a dream (you may need to change the ear tips around to get the correct fit) They stay put in my ears and block out a fair amount of outside sound if you get the right fit. Aside from they they just sound great.
