The stereo speaker distortion thing has to be software related. If you start a track, hear it distort, click the volume down 1, then right back up, it goes away and sounds awesome.
My earpiece is excellent. thank the lord. LOUD and clear. Having a bad earpiece, quiet or crappy, is the main reason i have returned phones in the past like, such as the N79 most recently.
The 5800 is reall a GREAT phone, to you know, make calls n stuff. which is #1 priority to me.
