When I purchased this model number, the unit intended for the right ear worked for a few days, then stopped holding a charge. After 2 to 3 hours, that unit stopped transmitting. Even after recharging, the sound was faint at best.I purchased the Asurion protection plan, but so far have not receive a satisfactory resolution to this problem.I have traded e-mails with the manufacturer, who is trying to resolve the problem. So far I have only 1 working earpiece, but the manufacturer is making a good faith attempt to send me a second unit that will work properly.I will update this review once the problem has been resolved.
