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.

You can try another cable, but I think there is something wrong with your driver... Maybe it is the dust..

Maybe MAchBot is right..You should try more
