No sound in left ear on Sennheiser PXC 550.
I realize that no audio in one ear is a common problem, but bear with me.
I already tried to see if it’s the audio jack that is causing it and did all the common fixes, but no luck.
Then I took apart the left side to try and see if it it was a wiring issue; yes and no. So the wire to the SP- on the PCB was not even connected, but upon soldering the wire to the pad, there was still no sound.
I did a continuity test with my multimeter to see if a wire broke and I actually got a crackling noise coming out of the left ear, so I guess that’s not the issue.
So now I’m stuck at this step and have no idea what to do (short of ripping apart all the wiring).

I have the same problem right now. Heavily disappointed that this seems to be such a common issue and yet Sennheiser hasn’t addressed it. I’ve had my pair for less than two years, and have kept them in great condition so I doubt that it is the fault of the user. Funnily enough, I discovered that the left earcup still works when you activate the different effect modes - albeit it is definitely fainter than the right one and music sounds off centre. Did you manage to get them working again btw?

I haven’t ventured into openings them yet as I don’t want to damage the exterior. Was hoping iFix it would have some suggestions on the procedure.

Is yours still under warranty? Because if it is then definitely don't take them apart as that will render them out of warranty.

No, they’re no longer under warranty, unfortunately
