"The best of the best! A pleasure to use."5.0 starson by picc47
Pros: Voice transmission quality is better than with my jawbone, which I was told had a slight echo. I was amazed at how perfectly the voice commands work, and pleased at how easy they are to learn. I find the headset extremely lightweight and comfortable.
Cons: I was concerned initially, because the headset wouldn't turn off after it's initial charge. Excellent phone tech support made a suggestion that worked. (How often does THAT happen?!) It's been perfect ever since. So really no cons.
Summary: Without the voice commands the jawbone would run a close second to the V1. But the ease of use and voice commands puts the BlueAnt V1 way out in front. It charges quickly, and by asking the unit to "check battery" the headset tells you if the charge is high, medium, low or very low - extremely useful information. (You can also speak the command "teach me", and the headset will talk you through a tutorial.) Charge lasts a more than reasonable amount of time...certainly much, much longer than my iPhone 3G. This is my third and favorite bluetooth headset, Jabra BT500 and Jawbone 1 being my first and second sets. I tried several programs for my iPhone 3g that promised to use voice commands. But I never found one that works reliably. The BlueAnt meets all my needs, and I can recommend it without reservation. I also recommend purchasing the Hard Shell Bluetooth Carrying Case for BlueAnt Z9 Z9i X3 V1 V12 made by Young Micro - it offers excellent protection.
