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...

will these components be able to drive this headphone?
ESS Sabre 9018Q2C dac Texas Instruments LME49720 amp Realtek ALC1220 audio codec
these components are part of my motherboard (aorus gigabyte z370 gaming 7) in the computer.
Instrument separation, overall clarity and resolution can be improved with even a cheap (USD 100) external DAC/Amp.
LME49720 amp has 23 to 26mA max output current. 6xx doesn't need much current (~8.4mA Irms 11mA peak for 110 dB SPL - that's pretty loud. ~23.6mA peak for 116 dB - that's really really loud)
The voltage supplied to LME49720 is sort of a question mark. 6xx do need some voltage. Assuming your motherboard and my motherboard grabs the same voltage rail from the psu, it'll get to about as loud as you'd want it but that's it. Any sort of digital EQ with -6dB pre-amplifying or more and you'll be asking for more volume.
In other words, you'd be at the limit of your motherboard driving 6xx. But I made some pretty big guesses and what you call loud and I call loud might be way different. Maybe your MB can squeeze out a little more voltage or significantly less- who knows.
side note: many premium headphones demand a lot more current than 6xx. also, there might be another buffer amp that isn't mentioned to supply more current. MBs leave a lot of unknowns >.>.
These are pretty good headphones and a steal at the price. I would just get them and get then add the amps at a later stage if you need them. The 580 might even be a better option.
i really just wanted to avoid having using an external dac/amp since it takes up quite a bit of space on my computer table.
i have an external dac amp lying around so i guess i'll have a go at them when the hd6xx arrives.
