My phone broke so i have to use a nokia 3600 slide phone which has a 2.5 mm headphone jack and i dont have such headphones so i bought a 3.5mm to 2.5mm fitting the phone adapter and i tried my headphones on it but they sounded pretty bad so i took them off but when i decided to use them later on my computer one side is quieter than the other and sounds bad. Could i have broken them by doing that?
