First of all I'm not really sure if this is the place to post it, if not i apologize in advance, but i'm having a problem with my IEM's. All of the sudden my PL11 started to misbehave, they play some of the instrumentals just fine, but vocals are really low and with a poor quality as well as other sounds. Feels like they are playing in the background but the quality of the sound is just weird. At first I thought it could be some problem with the cabling being broken at some point, but i tried twitching all the cable by sections and it didn't change a thing, even near the connector. I must say I do use them to go to the gym, so it could be a sweat problem. Oh and this happens to both left and right earpieces, can someone help me out on a solution for it? Should I just buy a new pair of IEM's?
