Well I did not need to sign in to listen, it played without any buffering, and sounded okay in a general since, no loud vs o soft, danced a little there volume wise, but no more than real life convo's. Do they have a time-out for your posting? Or do you need to download the program before it goes bye-bye off into the internet land of rewritten bytes?
Oh sound quality for me was pretty good, no hissing, snapping crackling or popping, and like I said above volume pretty consistent.
