"Great Bluetooth as long as your phone setup is correct!"5.0 starson by MeSasquatch
Pros: Excellent noise cancellation, great speech and listening clarity both ways. Cool desk stand/charger, comfortable. Have to see my full review below (expand) to see all of what I wrote because of text limitations here.
Cons: Had to heat the ear hook and bend to better shape to fit nicely-no big deal. Have an LG env2 and the H15 sounds great to others once I realized to set "Voice Clarity" OFF and "Voice Privacy" OFF. Basically, the H15 competes with the LG built in stuff
Summary: Pairs to two devices. Has excellent noise cancellation and sound clarity. Here's a great test for noise reduction and this is what I did. The day I got the H15, after it was fully charged in the cool desk stand, after 9:00pm on free airtime with Verizon, I drove around with the car stereo on at a fairly loud volume, car was cold so heater fan was on at 75%, with the drivers window open about 6 inches, anywhere from stopped at a red light to 50 MPH. I called 800-GOOG-411 which I use ALL the time. If you've ever used Google for looking up numbers and connecting you know what I mean when I say that although a GREAT service, if there is background noise it will say "starting over" or "just say the city and state" or whatever. Goog 411 says quite a lot actually. Here's what I experienced: I was looking up obscure places with strange sounding names: like Ski-N-See Sandy Utah, Alta Ski Area Salt Lake City Utah (pronounced "all-ta"), Dem Bones Louisville Kentucky (BBQ restaurant), etc... Even with the all of the background noise, it got them all right the first time. The H15 is also full duplex so you can interrupt (true two-way communication). I would say "go back", "start over", "details", "connect", etc... while the Google voice was speaking and it would go straight to that command. I've had 3 other Bluetooth headsets and have never been able to interrupt the voice without waiting for a pause in the speakers voice. Also, with my previous BT headset, my wife HATED when I used Google because she had to roll her window up, turn the radio off, turn the heater off and be quiet (All not easy to ask for in the Rockies in the winter with wife in car!!!) she reads this, I'm a dead man LOL. That proves the noise reduction works very well. On to the sound quality. Hearing the caller sounds more natural and has a deeper sound to it. More base basically. My Mom and Dad like to hear people like they were on landlines. My Mom and I talked today for 4 hours before the battery went dead on the H15. For most of the conversation she didn't even know I was on the H15 Bluetooth. I have not heard any complaints from anyone about my voice from anyone once I set my phone as I listed in Cons section. Make sure whatever phone you have to turn off any noise cancellation it might have as it will compete with the H15 and make your voice sound "robotic" like some people have written in their reviews. I also have a Motorola i860 Nextel phone for work and the H15 pairs to both phones perfectly and sounds great on both. I left myself a voicemail from my Nextel to my Verizon and it sounds like I am on a land-line phone.
