Cutting to the chase about any bluetooth headset, the following are the criteria a headset should be judged by:1. Sound Quality/ Background Noise Cancellation2. Comfort in wearing for prolonged period of time/ Wearibility3. Battery Life4. Overall aesthetics/Ease of Use.Here's how I would judge the Motorola H700 on each of the criterions:1. Sound Quality: Bluetooth headsets are inherently limited by the nature of the technology in reproducing the sound quality that one has come to expect from corded handsfree headsets. That said - the H700 has the best sound quality paired with either my Treo 700p and the Motorola V3m that I have seen in any bluetooth device. I have been told that ambient sound levels like road and wind noise is also significantly reduced at the listener end. Overall, I am very satisfied with its audio performance. Can it be better? Certainly -but this is best in class now.2. Comfort: Very light. Very small. Very comfortable to wear. Matter of fact, I wear it all day at work without any discomfort.3. Battery Life: I travel a lot for work. And I am a very heavy cell phone user. And I can go on using the headset without re-charging 2-3 days in a row. Good enough for me. I haven't tested the outer limits of the battery so I cannot comment. But its very satisfactory. Also standby times - I have personally seen standby times of a week or more.4. Overall aesthetics/Ease of use: Because of its flip boom design, it is very easy to use - easy to switch on and off. The switches are intuitive. And overall, the headset itself ( and this is entirely subjective) - I think is the best looking headset in the market.I would buy it again - if I had to.
