I am having both the Jabra BT500 and BT135. Very satisfy with their voice quality. However, what I brought for my girl friend is the BlueAnt X3. Its cute design caught my attention. My girl friend loves it so much that she never answer her phone without it. She said it's easy to set on her ear and very comfortable. We both satisfy with its voice quality as well. I'll highly recommend to anyone who is looking for one.
