"Decent sound, but overall, horrible call quality."1.0 starson by BruthamanQ
Pros: Comfortable (for short periods of time only), decent sound in your ear.
Cons: Heavier than Jabra claims. Callers can't hear you. Poorly designed.
Summary: My first impression was that I could hear my callers very, very well. However, it soon became apparent that my callers couldn't hear me well at all. What a frustrating and poorly designed headset. The microphone is practically positioned behind your head. My callers complained of muffled conversations. Oh, they could hear me just fine. Only, they couldn't understand a word I was saying.
Only benefit was the ability to use rechargeable AAA batteries and the huge amount of talk time (15 hours, claimed.) But who cares when you can't even have a conversation.
After twenty minutes or so, this heavy thing starts to hurt your ear. It's heavier than Jabra claims. I went with the Motorola HS 805 which also uses AAA batteries, and I rate the Motorola a 7.5-8.0 out of 10.0.
This Jabra is terrible, and by the way, so is the A210 adapter for non bluetooth phones. I have the A210 and it constantly goes into stand-by during my conversations.
Can't wait to use my Motorola with an actual bluetooth phone when I am eligible for an upgrade with my wireless provider.
