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 looking at the design of these iems and recognizing that it's very simplistic - almost like a proof of concept. Can we get decent bass out of a very small single driver? yes we can... but there will be a compromise in quality (for some) in he mids and highs. There are several physical design decisions that I don't want to get into, but that I believe contribute to this.
That being said, I think I've figured some things out that explains some of our different listening experiences and certainly makes MY experience a small but noticeable bit better.
1. The back caps - tightening them down on the cable makes a better seal (rather than creating an inadvertent untuned bass reflex design (ported)). There's a mod that was originally for the pro version but I think applies to the non-pro version equally ... or rather, I think that if the cap isn't squeezing the cable, you get bass bleeding all over the place.

2. I'm not a fan of the long and narrow pipe when it is extended by sound deadening material that preferentially absorbs higher frequencies. So I was going to cut off the very tips of the comply tips ... until I found a video, recommended on the comply website for those experiencing high freq rolloff!!! http://www.complyfoam.com/faq/ It's the second video. Here's a more direct link to the video:
3. apart from pulling back the foam, insert it slightly backward facing and do not push it to the end. When I insert the iem, I press it into the back and then back off a bit. This provides a more direct sound path and prevents me from overly deforming that path. (Every ear is a bit different - I have to push it slightly downward as well)
My next experiment is to purchase larger comply tips that will hold the direction better. I'm getting an ok seal now, but I think larger will be better. Also - I am getting ts-200s as I wonder if the earwax guard (in our tx-200 model) is altering the sound.
It's unfortunate that these design decisions result in variable listening conditions and thus very different opinions from each listener. There is always some variability, and now there's even more. That being said, if sound is your hobby, these iems will keep you busy. :)
Anyway, these are just ideas to try that I found helped me better enjoy my listening experience. If you were as disappointed by your R2As as I was, I hope these ideas help some.
... "I think the tx200 could be easily modified cutting away the filter and the top 2-3mm foam minimising the tube obstruction." ....
Funny I just did that. Literally right now. I was just going to post my clever idea :-). My results are similar to yours.
Also of note - I find it better not to overly squeeze the tips and not to overly insert them.
No significant change in sound quality with a heck of a lot more useful features.
