See my title? That is how you type the sound of the the echo you get using this headset.It was very inexpensive, and maybe if I spent a few hours on the phone each day I could understand wearing a bluetooth headset all day. It was comfortable for the few minutes that I used it. But to tell you the truth I decided that unless I end up spending 4 hours a day on the phone some time in the future, a bluetooth headset will never actually be worth the money spent on it.I returned it after a day (I didn't even bring it home with me from the office that night, I left it on my desk to repackage in the morning)
