When i use mp3go 2.02 with my headphone the sound is too low with this...and however i can hear the sound also by the 7650's speaker !
:(
Sometime when i plug the headphone the mobilphone doesn't recognize it and the music is very high and perfect with headphone...but also higher with 7650's speaker....
How may i turn off sound by the phone and amplify the headphone?
Pls help :( i want to use it like an mp3 player...but i can't use it so during an university lesson :)

Don't know about mp3go, but if you really use a 7650 to listen to MP3's, then with the limited amount of memory that the 7650 has, you must have very, very short versions of songs on the phone, or just one that repeats.
