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...

----- As an aside:
Andrew was suggesting a BNC ended coax cable (need 2) https://www.digikey.com/product-detail/en/pomona-electronics/2249-Y-12/501-1821-ND/736317 (various lengths possible but going short 12") along with a BNC to RCA adapter (need 4) https://www.digikey.com/product-detail/en/cinch-connectivity-solutions-aim-cambridge/27-8110/367-1012-ND/385337
Alternatively, for the DIY crowd... RG223 coax -- https://www.pasternack.com/flexible-0.216-rg223-50-ohm-coax-cable-pvc-jacket-rg223-u-p.aspx
I'll try this analogy. Not sure if this is perfect, but here goes: Think of tying a 3" dia. 18' rope to a Costco ceiling 20' above (an impedance termination mismatch), then lie on the floor under the rope and move the rope end back and forth 2' faster and faster until you see the middle start to bow out back and forth - a standing wave (reflection with constructive interference). Call this freq the fundamental resonance freq of the rope and note how the rope itself is starting to actually pull your hand (the source) back-forth due to the standing wave - i.e. presenting a problematic impedance for your hand to move your hand as you desire (causing overshoot or undershoot, perhaps). Then shake it faster and faster, and observe as the standing waves magnitude reduces (reflections still present but not as constructive, easier to control with your hand), followed by a return of more dense standing waves at multiples of the fundamental freq and difficult to control again. Ok, so this establishes that mismatch of rope impedance to termination impedance is problematic for the source when near or above the rope's fundamental freq. Next, shake the rope end the same 2' distance back-forth but way slower: 1/1,000th the frequency. No more standing wave, and no fighting the rope standing waves to move your hand. So we can say that exciting the rope well below its fundamental freq means the impedance matching of rope to ceiling termination is no longer useful in predicting how it loads your hand.
I wonder how a portion of the audiophile community here might react to your take on 'high-performance' cabling?! ;p Nevermind. ;) Cheers.
