Summary: Looked like a great product. Received the first one with no instructions. Could not get it to sync with my phone. Tried to fully charge it. Still no connection. Received ths second with the same results. Either the used ones have bad batteries or my phone doesn't work with this product. Brand new Verizon Droid 4.
Cons: The connected devices keep disconnecting. I agree to the reviews from CNET users that it will really cause accidents while trying to pair the device with the mobile phones. The only reason why you buy a bluetooth earphone is for the convenience. In this c
Pros: I liked the overall physical design; and the idea of have a secondary charger for when it went dead.
Cons: Length of run time per charge was not very good; a few hours (typically two or so for me). Would not stay put in my ear no matter what ear gel I used which caused me to always have to mess with it and constantly try to push it in while talking.
Cons: Headset doesn't fit snug. It hurts the ear when trying to keep it in so that you can hear. The design is for a small child and not an adult. I have to hold it in my hear to talk. I am extremely dissatisfied. A wait of my money.
Cons: It's a pain to use....it's horrible It constantly disconnects from my iphone, when it pops out of my ear canal it disconects the call because pushing it is the function you use to disconnect. it does not fit the ear very well, it's crap.!
Cons: Stone does not stay in my ear and falls out doing simple tasks. it no earpiece modification. There are no resolutions to this according to Jabra. I don't have unusual ear problems. My old Plantronics works great. I purchased as a whim from AT&T.
