Query: I was very disappointed.

I was very excited to have the hands free, but people keep complaining that they can't hear/understand me. It is very frustrating. It feels loose on my ear like it might come off, but it doesn't. I guess I got too excited reading the rave reviews saying how crystal clear the sound was. The hands free in my car is better. It just didn't back up the hype.Otherwise, it works, it is pretty easy to use & very easy to set up.
