I stopped using my UM3X for a short wile as the jack wouldn't connect to my iPhone with it's case on - first word problems, I know. Anyway, I've dusted them off and have used them with my MacBook, iPhone and iPad. On all three devices, the volume is terribly low. I need to set the volume to max and even still the sound is low in both ear pieces.
What could this be? Faulty cable, blown driver? Appreciate any help.
