"Easiest to use and most useful headset I've had by far."5.0 starson by OK_oilman
Pros: -big advance over previous headsets
-voice commands are very useful once you learn them, doesnt take long
-voice prompts very helpful (battery, connection, caller ID, etc)
-noise reduction great for driving and normal situations
Cons: -voice help prompts don't tell you eveything they should. Had to hunt through guide to figure out how to hang up a call (doubleclick).
-strong winds seems to kill performance of voice control and mess up call quality
Summary: Fantastic headset but not completely handsfree. You do need to push the button to make it start listening for you commands, and push it (twice I found out) to end a call unless other caller hangs up. I've probably used Redial and Call back commands over 100 times in the week I've had it. Works great in a car and in office and mostly outdoors..
Strong winds seem to kill the voice command ability though so beware of that.
Voice commands are intuitive, just have to remember the "What can I say" command and the others stick after a a while. It's not smart enough to understand partial commands though and if you say the wrong thing a couple of times it has started doing something you don't want. Once it starts dialing though you can't just say cancel, you have to click to cancel. It tells you what its going to do so you have clear warnings if you need to cancel something. A nitpick but the voice command value greatly outweighs this minor nuisance every once in while.
Caller ID and voice answer is truly handsfree and eyesfree, no button push at all, and is great if you are frequently tied up doing things like I am. Does only caller ID by number though.
Voice prompts are immensely helpful. Use to have to take off gloves pull phone out of my pocket to know if headset was actively connected to phone or if I need to go charge it. Just ask this thing and it tells you.
Noise reduction in car is great people can hear me clearly. When working outdoors Iin noisy environments have to switch to the max or people complain on background noise. When switched to max I do have to repeat myself some so not perfect. My previous noise reduction headset was unusable in such situations still big improvement.
Tried the Goog411 function once, this seems more useful if your travelling or looking for something new. I'm sure when I travel I will use this more but have not yet.
Battery life has been good, so far no need to charge during a workday.
