@Brad Saucier that did it! First I tested with another pair and it worked, then I noticed that the second pair didn't have the mic 'mark' in the plug (no idea what's that called). So I ended up using a female to male P2 adapter without mic support, and now I can use the same pair as before. Thank you very much! Since I use these hadphones daily at work I never imagined they could be the culpirt. I'm just glad the jack is not faulty. edit: I couldn't find an option to mark this as solved

Hi, I'm pretty new to keyboards and musical instruments in general, Monday is my second class. In any case, I've just bought an used S300 and everything works well except for one minor thing. When I connect my headphones, any tone other than the first has a very very low volume. The first tone sounds perfect, just the others that don't. What's even more puzzling is that if I unconnected my headphones, all the tones sound equal. Is this normal behavior? Anyway to fix it? I can hardly hear anything when I change tones with my headphones on, I've been practicing only with the first default tone. Thanks in advance.
