hi...i got my arc s this week but i got a problem with earphone..when i plug phone detect its not compatible with phone then i try open fm radio and insert only 2 ring then it detect but the sound is terrible...too slow and no bass at all...how to solve this ? i need to use sony earphone only ?

thanks..

well sorry...i tried another 2 earphones and no luck then finally i tried a4tech headphone and it works...then i realized that a4tech hp only got 2 ring jack but other earphones was 3 ring...

btw that a4tech hp when i plug into pc i can only hear on right side with no bass...left side too slow...but when plugged into my arc the sound is superb with bass of course...

why is that ? 2 ring vs 3 ring jack...whats the diff ?
