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.

But if you want a tldr. Once you remove the PCB from the casing the op amps are pretty easy to find as they are the only electronic part you can remove by hand. You replace it with the op amps found here and follow their guide: https://www.bursonaudio.com/products/supreme-sound-opamp-v5i/ after that it should be good to go
I like the LME49720 op-amps, but they are quite neutral and detailed with good sparkle,
The OPA2227 is lusher and a bit warmer.
AD8620 will need to be bought with an apadtor but is also an excellent op-amp with a very detailed sound, good soundstage and good sparkle.
IMO best to stick to true neutral in amp/dac and rely on the end of the chain(speakers/headphones) and/or EQ to color sound to your liking.
