UR22C - Uneven Audio Balance on Headphone Output

Hey there,

Currently have a Shure mv7 running through my UR22C to my PC and figured I should probably be running a wired set of headphones through it as well for my PC audio. Picked up the ATH-M20X and plugged them in, super happy with it, except there’s a noticeable imbalance between the right and left cups in the headphone where the right cup is louder.

I’ve tested them plugged straight into my PC and the audio is balanced there, so I know it’s not the headphones. It could be the adapter shipped with the headphones to allow it to be plugged into the interface, I’d just like to rule out me having configured something in the interface itself wrong first before I start getting replacement parts.

If anyone has any ideas that could help, it would be much appreciated
