Review on Bluetooth Hands Free Headphones Cancelling Compatible Cell Phones & Accessories for Accessories by Joe Lara

I have ordered several Revain headphones, most are well made but difficult to hear. It actually has a louder sound in the headphones so you can hear it. The call quality is ok, some think the sound is a bit tinny. I'll have to try how someone could call me. It tells you the number when someone calls, quick auto pairing. I haven't heard anything about low battery or full charge etc. But I invite it and find out. I use Plantronics M95 where it is crystal clear and very loud.
