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...

1) We have to separate the technology of balanced armature drivers and dynamic drivers. They have a totally different set of pros and cons. a) Balanced Armatures i) Pros - High speed, high efficiency, small size, venting not as much of a concern. ii) Cons - Inherently high distortion outside of a very specific range they are tuned for hence the improvement that can follow increasing the number of drivers. b) Dynamic drivers i) Pros - Cover a wide range of frequencies easily, slightly slower to develop and dampen can be perceived as a 'warm' low end ii) Cons - Lower efficiency, must consider whether to vent (isolation vs. simple pressure management), slightly slower to develop and dampen low end is less precise than BA drivers, larger in size (size is an additional complication as when wavelength increases the dispersion pattern changes dramatically). 2) We have to consider the pros and cons of a multi driver setup. a) Single Driver i) Pros - No crossover necessary, no time arrival differences, smaller in size than a multi driver setup ii) Cons - Building one driver to cover the whole frequency range is difficult, particularly in the form factor of an IEM. b) Multi Driver i) Pros - Can use specific elements tuned to specific frequency ranges. ii) Cons - Use of a crossover introduces phase shift (amount depends on slope of crossover), use of multiple elements in different positions introduces time arrival differences at the ear drum, takes extra space.
The more I think about it the combo of a dynamic driver on the low end with balanced armatures for mids and highs makes more and more sense to me. Most people enjoy the extended frequency response you can get by using multiple drivers and we've figured out ways to solve the problems introduced (time arrival and crossover phase shift) but the challenge most balanced armature IEM's I've heard have is that at least one of them is just trying to do too much work and ends up sounding harsh at higher volumes (distortion is what clues us in when something is loud).
I don't know the exact crossover points used in the W300 (I am listening to Melvins - Houdini on them as I write) but my suspicion is that the dynamic driver is doing a lot of the heavy lifting here up into the lower midrange (1.5khz or so) where the balanced armatures pick up. If I'm correct that means the dynamic is handling about 6 octaves of range leaving the BA drivers about 2 octaves each.
