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...

I know the way to go for most people is windows and foobar2000, but I haven't been using Windows since 2006, so some recommendations would be whole heartedly welcome.
Product is amazing by the way, my HD 380 pro and beyerdynamic 1350 CC really loves it. Now I can't wait to get my th-x00 shortly (:
I also got a stupid question, that probably has been answered before. I thought it was suppose to have a low and high power mode when you plugged in the seconds USB connector. But it doesn't seem to have any effect. Both my phone through USB C to micro B on the m9xx and my computers usb ports seems to power the amp just fine alone to around volume 85 (and to 99, not done any listeting on that volume tho since its too loud) which seems good (w/ AKG k712). I can't hear any distortion or anything.
Does that mean I'm under the low power limit, or does it mean its sucking more than 5v 500ma from the USB off my phone / pc, or am I under the low power limit with my k712 around 80-90% volume?
m9xx High Power mode: If you connect power to the 5V 2.0A jack before connecting to a USB host, the m9xx will only draw current from the 5V 2.0A source - no current will be drawn from the host. This is so that you can use your portable device as host and not draw its battery down. 500mA is the limit that a USB 2 device may draw per the USB 2 specification. If there is a power source connected to the 5V 2.0A jack (regardless of connection sequence), the analog circuits' power supply is higher voltage than if power is supplied only through the USB 2 port. Also, current is limited to 500mA through the USB 2 port but the 2.0A port of course can draw up to 2 amps. Whether you're connected in High Power mode or not won't necessarily make any difference in performance. Yes, the higher voltage makes about a 4.5dB increase in maximum voltage output. That probably makes no practical difference unless you're driving very high impedance headphones that need large voltage to reach desired SPL. However, if you have a heavy load (low impedance, low efficiency headphones, loudspeakers), it's possible that you may be approaching the limit of current that the m9xx can deliver with only a 500mA source. With a 2 amp source, the m9xx can deliver a lot more current. But, that greater capability may not make a difference if your load does not demand it.
