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...

This is kinda of an important question, so hopefully it can be answered before the product launches. Answering something so important about the product specifications only after the drop ends is not an honest way to sell a product. Serial resistors will need a lot of clock cycles to output all the data. Parallel can output all the data in 1 cycle.
Also does this have an FGPA doing resistance correction of the ladder? Or are you relying on the resistors entirely?
The core of the conversion is a resistor ladder with 24 rungs, corresponding to the 24 bits of each sample. The entire sample is converted at once. In a sign-magnitude design like this, there are two such ladders per channel (four total in this DAC) operating simultaneously.
