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...

People think higher impedance heaphones need more power to sound as loud as lower impedance ones, but that's completely wrong, they just need more voltage but less current. The thing is that most solid state amps (the ones you can find on embedded IC in every PC/smartphone/tablet/whatever) are good providing current but struggle to output high voltages; that's why the higher the impedance load, the lower the power they output. But the only spec that determines the power needed by some headphones to output sound to a given volume is the sensitivity.
You can check exactly how much power (voltage and current) does any headphones need here: http://www.digizoid.com/headphones-power.html. BTW, most companies list the sensitivity as dB/mW (which is absolute) while some others use dB/mV (which is relative to the headphones' impedance). If not said otherwhise, consider the sensitivity is listed as dB/mW.
