I've been using the
Cardo S800 for the past couple years and have never had any problems with it. Pairs to devices quickly, sound quality is excellent (on both ends) and best of all its small form factor and innovative earhook design make it surprisingly comfortable, almost to the point that you forget you have it on. There's a good chance there are superior bluetooth earpieces out there by now, but if you can find this one for a good price, I recommend giving it a try.
