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...

Skip to bottom for tl;dr.
*The good: - There's an obsession with female vocals in Chinese and Japanese HiFI communities and the K5 is very much if not only specifically tuned with this in mind. This is a fairly neutral IEM on the brighter end that emphasizes mids and a bit of lower treble. When you get the right track, these can sound pretty nice.
- The build quality of the IEM units are pretty good, stock tips are comfortable, although after markets like Spinfits are still recommended.
*The neutral: - The stock cable on the V2 from what I read is a significant improvement over the V1's which must've been utterly disgraceful considering how average these are. The pictures make it look better than it is but this is a standard 4 core 4N silver-coated copper cable that simply works. I used it for about 30 mins before swapping in my Beyer Xelento cables. APT-X supported BT cable works and is a convenient inclusion.
- The K5 is slightly bright and ultra sensitive. Avoid brighter and high output impedance sources, driving this out of the Hiby R6 for example, produces a sound that I will politely describe as unpleasant. Use IEMatch if you want to use high OI hardware.
*The bad: - Soundstage of the K5 is weird, in a bad way. The vocals are so forward that the lows, particularly sub-bass sounds like its all the way in the back. This creates an illusion that the soundstage is wider and the separation is better than it really is. It actually sounds decent in vocal focused tracks or tracks with single sounds in a wider array of ranges but play something with multiple sounds in the same freq. range and it starts getting messy. Now, sound is always subjective and you might love it but to me, even with the right tracks the soundstage feels unrealistic.
- Chinese BA drivers. Chinese DDs have come a long way and are fairly reliable. Chinese BAs however, are not. There's a reason even DIY IEM makers on Taobao tend to use Knowles and Sonion. There are exceptions but too many times the extension, precision, speed are just not there. A good example would be the 5BA KZ ZS10. However, the ZS10 is also 5 times cheaper (in China) than the K5.
*The Ugly: - K5 is produced in a Chinese factory and sold under different brands. Internationally, you can more easily find it as the NiceHCK HC5. I could be wrong but given that they come with different accessories and different price points and that HCK and Magaosi don't share other products, I don't believe this is the same company. This and the tuning that fits only a specific music profile tells me very little effort actually went into properly tuning these.
*Tl;DR / Conclusion: - Despite an unrealistic soundstage, paired with the right source and the right tracks, the K5 can sound pretty good. However, the lack of proper tuning and/or driver quality means your listening experience will vary from good to harsh and unpleasant. If this was between $20-$40 like TRN V60 or KZ ZS10, it might be worth as a niche pair but at this price point, TFZ King Pro/Queen or QDC Neptune are the Chifi IEMs you're looking for.
