Thanks Dan,

That's pretty much what I read about them. A new concept that actually works well. I have also heard that the listener on the other side hears a kind of robotic tone to the wearer's voice. Would you agree? Not really a concern for me as all reviews say the funny tone is preferable to not being able to hear the person.

Besides who doesn't want to sound like a robot??

With great power comes Awesome irresponsibility.
