I was so psyched when I got this, but pretty much everyone i talk to tells me they constantly hear themselves echoing whenever i'm using the H3. They wind up begging me to turn it off which isn't as simple as it should be and then viola! the echo stops. Reading all these reviews I can tell i'm not the only one having this problem, so i guess getting it replaced isn't going to do much good. I bought it online so i'm guessing returning this isn't going to be simple. That's my 2 cents. Try something else.
