Why did one side of my phones just quit working? I was careful to not blow it out with too much sound level. What’s going on?

Well, we can’t say for sure but there are a couple possibilities – could be an electrical short from a bad cord, or overhead wire – or it could be driver corrosion.

Driver corrosion happens because UltraPhones use SONY 7506 components in a way they weren’t designed to be used – mounted in an enclosed ear cup. This enclosure is designed to block sound. It does not breathe because if air gets in, sound gets in. If you perspire when you perform this moisture can eventually cause the driver to corrode and stop working.

Corrosion takes time, so if you do sweat a lot when you play, leave the phones out of the case to dry before putting them away. This won’t eliminate the corrosion but it might buy you more time before the driver fails. Also, everyone’s body chemistry is a little different, some more corrosive than others, just ask a guitar player or bass guitar player. Some guys can play the same set of strings for a long time before they go dead. Others have to change them much more frequently because they go dead from their touch.
