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...

I was driving my IEM (Triple Fi 10, Balanced Amateur Drivers) to test it out. I had to have volume knob at very low as BA-driver is much more sensitive and lower in impedance than the larger headphones (close to a point where volume cuts off to silence for me, which is also the point where minor channel imbalance could occur from O2 Amp design as this utilizes analog volume potentiometer) but that lowest level was at more than comfortable level. Therefore, I did reduce the input level (from PC) slightly lower which reduced the softest output and let the gain from amp do its job (since when we consider how amp works, it's simple as output = input + gain; You'd also have to think about impedance of sensitivity to see how that output would drive the IEM). Downside is, if you reduce the input too much and fully rely on the gain it could cause more hiss. For this, you could also utilize an attenuator to bridge between your IEM and amp which would utilize resistance to reduce the output reaching to your driver.
But remember, if your IEM is sensitive enough to be fully driven by whatever the source is, you don't need an amp. utilizing DAC however, is different story because your output method from source may provide dirty signal (like PC mobo 3.5mm jacks for example).
I did have to slightly lower the input level to have my softest comfortable level past that 8 o'clock (currently it's around 9 to 11 o'clock for softest comfortable to loudest) and didn't have any imbalance since. I tend to listen to music at softer level than many others so over-amplification at the quietest level was my initial concern. Thank goodness this is 1x/3.3x not the normal gain.
I hope my two cents can provide better judgement in your purchasing decision.... To bias you even more with my opinion I really like how mine sound :P
