• Bluetooth wireless technology means that the sheer convenience of hands-free communication is enhanced with total freedom of movement.
• Unfold the boom microphone, place the headset over the ear and a link will be established automatically.
• This universal accessory encourages users to update, change and evolve because it is compatible with all other 1.1 compliant Bluetooth wireless technology phones by Motorola and other manufacturers.
• Smaller Size, Bigger Power. This tiny powerhouse is less than 5 cm in diameter when folded and weighs just 20 grams.
• Increased talk time of up to 8 hours and standby time of up to 200 hours.

No wires. No limits. Designed to enhance the experience of any Bluetooth technology enabled phone, the Motorola Wireless Headset HS850 also stores information and wirelessly interacts with up to eight different Bluetooth 1.1 and 1.2 compliant devices, including handsets, PDAs and computers.

The HS850's audio properties are also like those of the HS810 before it. The audio quality in both directions is very clear and understandable, but sounds a bit thin. You and the party on the other end of the call will both be able to understand each other easily, it just doesn't sound as full and natural as it might with some other headsets. The HS850 makes up for this small lacking by having great resistance to wind noise, though. That makes the headset perfect for people that enjoy driving with their windows down, or those that work outside. Most headsets are very susceptible to wind noise, the HS850 bucks that trend.

And now for the new stuff. First up, a more powerful battery. The HS850 I tested managed an amazing 7 hours and 50 minutes of talk time. That is a full two thirds improvement over the older model. The truly amazing part is that this new battery life didn't come at the expense of added weight. Like the HS810 before it, the HS850 weighs only .7oz (19.9g).

The next major change perhaps sounds more important than it worked out to be in reality. The HS850 supports the newer Bluetooth v1.2 spec, whereas most headsets support v1.1 only. Motorola claims that when used with a v1.2 compatible phone (there are still relatively few available at the time I write this), the HS850 will be able to connect faster, use less battery power, and offer improved audio quality. While I can see what appears to be a slight improvement in connection speed, I haven't really noticed much of a change in battery life or audio quality.
