The BlueAnt X5 Bluetooth Stereo Headset sounded pretty good using Skype. My contacts said the headset sounded great to them. But after about 10 days the audio from iTunes and Skype started to sound gravely and not as loud as when I first installed. The Blue Tooth link is simple and the unit relinks to the phone or the streamer very easily and quickly when switching.Update: The distorted audio has gotten worse over the last few days and I have stopped using the X5 and have bought another brand of wireless headset.
