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...

Regarding tips, the default tips did not work well for me and as others have said, tip rolling is necessary. The small/medium were too small/too deep insertion (my ears canals aren't symmetrical which makes this even worse) and the largest was too large (why is there 4 sets of it instead of 2 sets of 4 different sizes?) though it did offer less roll off, less congestion and better staging but less isolation than the smaller sizes. Trying other tips, my best results ended up being with the tips for the Brainwavz Blu-100 which seemed to counter the treble roll off and clarity a little at the cost of bass quantity and isolation, and some other tips intended for KZ iems which had better isolation and less loss of bass than the former.
I also noticed that the Primo 8 is very sensitive to sourcing and would guess that source output impedance (i.e., higher is worse I suspect) can greatly affect the sound. It works fine with the FiiO X5ii (silent I think; but the inline volume control on the Primo 8 is incompatible) but with the m9XX there quite noticeable hiss. Other sources like my phone were ok, but some sources like my laptop or desktop's onboard audio and Nintendo 3ds work terribly with it: more treble roll off (perhaps comparatively) and emphasized (and perhaps muddy) bass/lower-mids. This wasn't noticeable problem with higher impedance headphones. Even using an old FiiO E17 acting as a simple buffer amp seemed to be sufficient to fix the problem. I would hazard to guess that the Primo 8's passive crossover doesn't play well with all sources and would be curious to see an impedance plot. I would also similarly note that the 4 pin 3.5mm connector has causes compatibility issues with some devices (e.g. original FIIO E10) and cable adapters - since the volume control is incompatible with some of my device anyway, I would prefer if it was not included.
Edit: Revised the above on 2017-01-24 after several months since receiving them from the original drop since I see this drop is out again.
