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...

A bit disappointing considering that my cheapo motherboard with a Realtek ALC892 has no background noise at all. IIRC Massdrop's original product page for the Slim advertised a "jet-black background", but I guess it's no longer advertised as such.
Although, sometimes your source could be to blame... have you guys tried using different USB ports to see if there's less noise? Oftentimes, front panel USB ports are very poor quality and generate much more noise than your motherboard USBs and even USB 3/3.1.
The fix for me was using a heavier shielded ferrite core USB cable like this:

Cleaned the noise right up for me.
I currently do not have access to anything above 32 ohm to test on, but at a guess I'd say anything over 50 ohm would probably be enough to cancel out the noise floor (maybe). I don't think I will be able to test this before the end of the current drop but i will report on it when I can.
Honestly hiss from the slim with my sensitive IEMS seems to bother me less and less... or it has lessened for real from break-in.
And yes, it happens on both low(line-out) and high gain.
It's a constant and very light white noise in the background, and as a result noticeable on low impedance cans and iems.
What confuses me is that moedawg140 says "[He] did not detect any hiss or background noise when using the DACport and SE846 combination."

Yet I can hear it quite clearly on all my headphones and earbuds if I listen for it.
