Legit Reviews has posted a review on the Motorola HT820 Bluetooth Stereo Headset
Incoming calls were registered on the Motorola HT820 almost instantaneously with a pleasant ring in the headphones. When dialing, phone calls were transferred very quickly to the headset – many times even before the call started ringing. I was easily able to go 35 feet or so away from the headset when talking which makes the range of this Bluetooth set excellent and one of the best we have seen.Motorola HT820 Bluetooth Stereo Headset Review
