Bose NC 700 left side not working when connected via cable
I've got this problem - when listening via Bluetooth everything works fine, but as soon as I connect headphones via cable, left side isn't working. I'm using original Bose cable, which I got when buying them.
I tried connecting them to PS5 and PC - same problem. Also tried unplugging it slightly, but it doesn't chagne anything. Again - if I'm connected to PC or my phone via Bluetooth, everything works fine.
Unfortunately I don't have any other headphones where I could check if cable is working properly.
Any ideas what could cause the problem?

It sounds to me like a broken cable connection inside the headphones. The cable will have 3 connections, Left, Right, and Ground. If the brass connection inside is broken or bent for the Left, that could be the problem. Are you willing to open them up to look? If you mostly do bluetooth and don't want to chance breaking something, then you may not want to.
