The concept of a wireless headset is intriguing. Unfortunately, this design does not fulfill its' promise.First, it is not a comfortable fit. It always felt as though it was about to fall off, and I was always aware of it's presence.Second, it does not work as seamlessly as the wired headset. Voice dialing did not work properly (you could never hear the prompt tone to know when to say the voice command). Without voice dialing, you lose much of the freedom of a headset.Third, you look like a total geek wearing this thing. Not only is it large, but there's also blinking lights to attract attention.Kudos (and gratitude) to Amazon's hassle-free and simple return policy. Back it went.
