I have not had these issues with mine, I do know that you need to have the mik by your mouth, the closer the better, I do agree that the earphones sound tinny (SP), I preffered to have the external speakers on and talk with the lovely Mrs. with the intercom. Also, make sure you have the AVC (Automatic Volume Control) on H (High) when you are riding, makes a big diff and does not activate until 2500 and then increases again at 3000rpm....very nice feature....I use my radio daily....the scan leaves some thing to be desired...but preset work well...
Best of luck and enjoy that new bike of yours...
