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...

It just awesome.
You can hear and look linnnnnner outputs and just no hiss with no clippings My O2 has custom Gain x1, x2 so Definitely No clipping in any conditions
(x6.5 makes some clips with high volume @ battery only) O2 shows clar sound, not like tube amps
Just pure Amplifying at all No more Harmonics, Hiss, Distortions, Buzzing
Pros
Definitely highest grade Audio quality
Pure Amplify Infinite number of volume levels Low output impedance(will not change Frequency Response of your IEM to Full sized Headphones like Er4-S, K701, HD600, T1 ,HD800, etc) Good design (to me) Selectable Gain Cons
No battery level indicator
Volume unbalance with low volume(cuzed by Character of Analog volume, just use upper than 9 o'clock, recommend over 12) Too engineering nerd style design (to somebody) __________________
Amps are not for make dramatic sound(Cables too) Amp helps source devices with high input impedance, that keeps low frequencys with poor amped portable devices or DAC works better If you use apple devices like iPod touch 5, iPhone 6 you don't need it at all(for sound quality, but it can be helpful to mental effects, so You may Feel better with out actually no sound changes)
P.S. Somebody have measurements of iPod touch 6 tell me! (FR, output impedance, etc)

Edit: I just read Millifoo's comment on this O2 might not be the same spec as NwAvGuy's design.
