I shouldn't say doesn't work entirely, but if I don't use the headphones for a good period of time (say a day or two) the left channel starts to work again for about 30 minutes or so, then it just completely stops working. Sometimes when I fiddle with my amp and turn it up higher I can bring the sound back into the left earcup, but it only works so many times. I don't think I've messed with the connector or anything, it doesn't seem to be damaged at all.
Does anyone know what the problem could be? And if I could maybe fix this problem myself?
