All songs sound horrible, even those purchased from itunes - so not a burned format issue. I am not experiencing the "bass" issue others describe, but more that certain layers sound distant and garbled. This layer is typically the voice layer on most tracks. I have tried many settings adjustments suggested by others, but nothing corrects the layer distortion.
This issue renders iOS useless for iPod functionality. Please fix ASAP.
Update: Sound distortion appears to only be an issue when playing through the audio jack. Playing through the iPhone's built-in speaker does not reproduce the layer issue.
Did you try re-setting the volume level for your music files in iTunes, and then synching again? If you currently have it set to zero, move it up or down, allow the change to process, then move it back to zero, let it process, and then synch your music. Someone suggested this earlier in this thread, and I did it, and it fixed the worst of the distortion (in my case, the upper midrange, including many vocals, sounded terrible). I still had to set the equalizer to "rock" in order to entirely get rid of the distortion on all tracks, but at least my iPhone music sounds good again. It was almost unlistenable before the fix.
Before you try this fix for all your music, you may want to experiment with a single playlist and see if the fix works for you. Also, if you have a large music library, turn off Time Machine before you do this fix, because TM will do a new backup of all your music files, since they have been altered. This seemed to slow down the process in iTunes. Turn it on again once all the changes are done.
This problem needs to be addressed in an iOS update, and I can't believe it was allowed to slip through in the first place. My iPhone sounded so terrible that I assumed it was my earbuds, so I bought a new pair, only to discover that the buds were not the culprit. My fault for not doing some trouble-shooting first; luckily I prefer the new earbuds, so no harm done.
