I have a 8300 with AT&T and just got the HS655. Sound quality is great as long as I have the phone at chest level but at waist level I get a good amout of static. I like to have the phone in my left pocket but use my right ear for the ear piece.
I've tried rebooting the phone as well are repairing the ear piece. Is there anything else I should try before I contact the seller and get another one?
