Sennheiser PC37X randomly goes bad after disconnecting the cable ?
Greetings, Yesterday I was using my headset like normal with my macbook, just listening to music and on a call with people like usual, and the headset was perfectly fine. The stock wire that came with the headset is extremely long and yesterday it annoyed me very much that it kept getting tangled with itself, so I decided to see if the cable is replaceable. I pulled out the cable from the headset and saw the adapter, and looked online for a replacement. Upon plugging it back in, the audio sounded extremely muffled and washed out. Im not sure what I did wrong to make it mess up like that as I've always taken good care of it, ive had it for about 2 years and its always just been chilling on my desk, but anywho I thought the cable just went bad and ordered a replacement. The replacement came, and the issue is still persistant, so I am not sure what the issue is I've tried multiple different headsets and the issue is not with the port, and I also tried it with my windows laptop and...

12V is probably the driving voltage of the circuit. It probably won't be a problem *if the adapter reliably feeds 12V* but if it starts dropping past that I would be concerned. There's a reason it's overspecified - there's almost certainly a buck-converter circuit that depends on being fed a higher voltage (i.e. 13.5-17V) so it can buck down to 12V, and there's a certain internal voltage loss inherent to such converters. If you feed it 12V it may be feeding 11.5V internally and so on.
I call on the Massdrop folks here as well - at best you are shipping a device with an out-of-spec adapter, and that's scummy.
At worst you may be violating the Creative Convention/No Derivation design license by substituting another supply unit. You have no flexibility here if the design specifies input voltage, and NwAvGuy was the kind of guy who doesn't miss much in his specs.
Cost and shipping is over $25 to Canada.
