Yea I played around with sync stuff and that didn’t really fix it… I am still getting audio only from the right side of the headphones… unless I don’t plug-in the aux all the way but that’s way to fidgity cause if I move the op1 when on the couch… it disconnects… so weird how so many people have this issue… I’m looking now at soldering this thing but I don’t know how to do that…
this may be silly but r u sure u are using a TRS stereo cable?
keeping stereo all the way thru your chain?
r u pluggin into a mono source at all?
Did you ever get stereo out of it? i have a similar thing to you, I can get sound on the right only while backing out the 3.5mm a little bit, but I lose the left side then. Same as you?
