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...

- Did the amp work with stock tubes? Silly question, but I just want to make sure it isn't a dud unit. If it did work properly, then go to the next question, otherwise try loading it with all stock tubes and making sure you don't have a bad unit.
- Do all the heaters light up in the tubes, including the 12AU7 (the one in the center)? The heater will glow lightly orange in the center of the tubes. It may take up to 60 seconds for the glow to really show, though it should be pretty apparent if you have the lights low or off in the room with the amp. If one of them isn't glowing, there is a problem either with that tube, or with the tube connection in the socket. If one of the tubes you've recently installed isn't lighting up, try swapping back in the stock Chinese tube for that position. It is absolutely safe to have mismatched tubes in this amplifier.
- If all the tubes are lighting up, the next question is how are you driving the amp? If you're using the usb, try going to an external source via the RCA, and leaving the USB unplugged.
And while the tubes do require some force to push in and pull out, be *extremely* careful with how much lateral force you exert when doing either action. It is somewhat easy to crack the glass at the base where the pins are exposed and completely destroy a tube. Don't ever try to twist them, and if you have to rock them out, be suuuuuuuper careful.
