The HT820 is the best bluetooth head set that I have used. One of the earlier reviews stated that the headset was not in stereo. Well trust me it is. I play music with my LG fusic phone from Sprint. My last phone also had Bluetooth but did not work as well as this phone. I feel this may be that persons problem. The source of the signal plays a big part of it. The headset also works well with my Mac. I get about a 30-35ft range off both the phone and Mac. It sounds great and the hands free phone funtion works great. My only complant is that it could be more comfortable. I would rate the comfort a 3 out of 5. If you buy this product and set it up RIGHT you will have a great set of headphones.
