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...

Adding a power supply will increase how much power it puts out, but it is just a standard 2A USB power supply -- you might already have one laying around that would work. A USB battery pack would also work.
Regarding using computer power (stolen from myself off of head-fi.org):
Even if your headphones are driven to sufficient volume using the m9XX's lower power mode (using USB #1 for signal+power), I strongly recommend using both USB #1 (signal) and USB #2 (power) if it's convenient. For giggles, I unplugged the 2 amp power source from USB #2 and ran self-powered for a little while. The volume into my HD650s was fine, but I swore I heard a little bit of USB/digital noise being injected into the sound. After plugging back in USB #2 and the subsequent reboot, the silence was dead silent again.
My computer room is a mine field of spurious RF and noise and I'm connected via a powered USB hub via a USB docking station, so I may have the worst-case scenario, but for anything except mobile listening (plane, train, automobile), I'd use both USB ports to ensure maximum headroom and the cleanest power.
