I just got an M240, it has the lastest 3.x.x firmware update.
I transferred a bunch of songs onto it, both through media player, and directly through explorer. Either way the songs sound crappy. Hard to explain really, basically sounds like when you get an MP3 that is messed up, just a distorted kind of sound.
The songs sound fine on my computer, and even when i copy the song back from the m240 to my desktop the song sounds fine on the computer. Already reformatted it. Any suggestions???
