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...

Truly balanced means the amp topology is balanced, not that a single-ended signal gets split. One amp circuit for each channel. The downside is that single-ended outputs are degraded because the balanced signal has to be combined in some manner.
Balanced in DACs means something a little different -- still one line-level amp circuit for each channel but also one DAC chip for each channel (full differential balanced). DAC chips have better performance and noise specs when used in a balanced configuration.
The best: full differential / true balanced DAC -> XLR -> true balanced amp -> balanced headphones.
Quick visual guide: If an amp has more than one AC transformer it will be true balanced. If it has one transformer but the literature says its balanced, try to find assurance that it is true balanced (ie, there are secondary wingdings used off the single transformer which is a substitute for having two of them). DACs will often have two transformers but the second one is normally not used for balanced operation you'll have to find assurances in literature but if you can see more than one DAC chip than it's probably balanced.
