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...

- if I disconnect the RCA cables, the buzz persists.
- if I disconnect power to the amp, but still am connected to the dac via RCA the buzz persists.
- if I disconnect power to the amp and dac, as expected, the buzz stops.
Now I don't know if this boils down to the units malfunctioning, or that I'm using an incorrect adapter, or the fact that it's all powered through the same outlet that my computer is connected to. I've noticed if I touch the aluminium casing of the amplifier the buzzing drops to an inaudible or almost inaudible level, and if I pick up my phone while charging through USB connected to my computer the buzzing is very accentuated, but if I hold it while charging from a different source there is hardly a difference, but if I touch, for example, the metallic leg of my desk it's only slightly accentuated. Oh, and I've also noticed wearing slippers or lifting my feet of the ground seem to lessen the buzz. I haven't tried connecting the amp and dac to a different outlet than my computer but it seems like the appropriate next step (to an uninformed commoner like myself) which I'll do as soon as I get my hands on an extension cord. Any advice from electrical wizards, professional or otherwise, would be appreciated.
