Query: Looks Better than it Works!

Very slick design, however, 8 out of 10 times I used it the person I was talking to complained about not being able to hear me. Very frustrating. Would have to take headset off and use handset, which defeats the purpose. I replaced it with a Plantronics Voyager 510 and people have commented on how well they can now hear me. Not as cool looking on my ear, but worth the good reception.
