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...

Now for the mods, I tried various positioning of silicon foam to shape the sound. First I tried a ring around the outside of the cans to kinda direct the sound and air going in and out of the cans from the outside. This made the headphones sound a little strange. Couldnt quite put my finger on it but it just felt like there was a section of upper mids that were missing, while still retaining extremely harsh S's. So next I did the opposite, I put a circle 50mm in diameter on the outside of the cans in the very center. Basically centered right where the speaker is located but stuck onto the outside of the cans. This actually sounded pretty good. There was hardly any change in sound signature, but it made the low end ever so slightly more pronounced and made the extreme upper high's ever so slightly less pronounced. Next I moved to the inside of the cans. I took apart the headphones and removed the piece that mounts the speaker drivers inside the cans. Once that is open I moved my silicone circle cutout from the outside of the cans to the inside of the earcup in the same place. Basically making that mod "permanent" in its location (easily removable, but I was happy so that is my permanent mounting place for the mod). You cannot see this silicon piece when looking at the headphones because it is now hidden inside them. Here is how the outside looks with the mod installed inside:
Once the speaker drivers are re-mounted in place, I made a semi-circle cutout of silicon kinda like a crescent moon shape. I put one of these crescent moon cutouts inside each earcup above the speaker driver and below the earpads. They are not visible once the pads are installed. This did shape the sound somewhat, and brought the low end response up just a little bit, however it did nothing to remove the high end over-brightness and the S's were still a major problem. Here is a pic of them installed:
And lastly what the headphones look like with the earpads both on and taken off and the mods installed:
