So I needed a replacement for my trusty Jabra 250 that had excellent incoming and outgoing sound quality as long as there was no wind. So my wife spills a soda all over it and its shot. I look around for a replacement and thru numerous reviews I come up with the Motorola H605 which looks good and is a Motorola.When I get it and try it on, it fits excellent and the sound quality incoming is great. Then I make a call...My wife complained that she couldnt hear a word I was saying, as everything was really muffled. I was in the vehicle at the time so I left myself a voicemail to confirm this. Its was bad, I couldnt make out half the words I spoke. My car is fairly quite (Audi A6) and the background noise sounded like I had all the windows open. I really wanted to like this thing, but its just not functional. I read about people contacting Moto tech-support and they claim this was designed for GMS phones and not CDMA phones. Bluetooth 1.1 or 1.2 is bluetooth. Shouldnt matter. I even went to motorola website to see the specs on this headset and they specifically list this compatible with ALL Bluetooth devices.I never save the packaging so this is going in a box with all the other devices I bought and don't work.
