Well, I went back to radio shack last night and made an exchange for another HTC one. Guys at the shack had no clue either but suggested I turn the beats off. Anyways, the new phone sounds a hair better. The hissing white noise is still there. My guess is that most of the Ones have it but people just don't pay attention to call quality as much as they should. It's always gonna be noticed by me now. Perhaps it's a combo of the network with the phone not being fluid. I really don't know. I love this phone so much that I'll just keep it despite the call quality. Hopefully a firmware update comes soon.
