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...

Physically, the rubber/foam/fabric is designed to move so much and for so long that the difference from never moving should be over in the first few seconds or minute. If the material changed a lot then it would fail quickly or keep changing. Like if it changed a lot after 100 hours of use then typically materials will keep up a similar wear trend through their entire lifecycle expectancy and it would never stop changing and then it could mean failure at only a few thousand hours of use. Obviously that doesn’t happen.
As for the copper wires in the woofer “tempering”, that’s complete nonsense. First, tempering refers to a heating and quencing process in some alloys, such as steel. Copper does not do this. Furthermore, tempering would require high heats that are not present in a woofer. However, copper can be hardened by hammering or shot blasting. An ultrasonic process can also be used but the power levels required are enormous and wouldn’t take place in a home speaker system or within the range of human hearing where most break in is recommended. Electrical conductivity of cold worked copper can be 3 % lower compared with the same material in its annealed (softened from heating) state. But speaker impedance has not been shown to change with time and neither annealing nor hardening processes seem to be occurring.
It kind of seems like physics would rule out most break in concepts. I cannot be certain though since many subtle things occur in high end audio. It would be interesting to see some double blind experiments on the subject but I don’t know of any.
