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...

@james444 is always digging up random IEMs and modding them with impressive results. He posted a few before and after measurements of the mods, and before long, we purchased a JVC HA-FD01 from a Japan to send along on our loaner program. Most of the folks who heard the loaner, at least those earlier in line, should be aware that I had only implemented a quick and dirty version of the mods. The "authentic" @james444 mods were much more intricate. I think @zerodeefex can tell you guys what a pain in the ass it was for him to do it right. I hindsight, I guess I could have paid my kids (with their smaller fingers) to do the proper mod for me. Anyway, the point I wanted to make is that the proper mods result in better bass quality compared to the quick and dirty version. GENERAL SUBJECTIVE IMPRESSIONS As far as words, not much more to say that already hasn't been said by others Is this a TOTL DD candidate? Sure! Why not? What's interesting is that the highs are fast. I don't think I stated this before, but we are talking about BA fast, but without the BA timbre. And most important: no f'ckery in the highs (and this is my issue with the Sony EX1000). There's no nasty lower treble peak that every DD IEM seems to have. But you guys who already have a modded FD01 already know this. This is a legit TOTL DD for $350? Get this and flip the bird with both fingers when you walk by a goober at the next CanJam wearing bright red IEMs with a white angel silk screened on the faceplates. Sucker... And oh, BTW, I'm retiring my Andromeda (actually my kid had had them for a while now). The FD1X has worked its way into my high-end portable lineup. This will be my fourth IEM in the past decade, the others being UERM (sold), Andro (given to son), Solaris and FD1X (these latter two will be in rotation). As far as the general tonal balance: Yes, sort of. Still has some upper mid-3-4kHz emphasis, but lower and mid-treble is fine, even slightly sedated with blue. The frequency response plot below is with the blue nozzles. The most amazing thing is that every DD I've heard has issues with the lower or mid treble. This may be the first time that the highs are smooth as silk for a DD! I will discuss more on the sound (bass quality, timbre, etc.) in the measurement sections below. NOZZLES The Drop x JVC HA-FD1X comes with three different nozzles.
- White = stock (same FR as HA-FD01)
- Green = modeled after @zerodeefex's mod tuning
- Blue = like green above, but just slightly pushed down more in the highs
The difference between the green and blue nozzles are not huge. I do say that I prefer to the blue. The frequency response differences between the nozzles are indicated below. The white nozzle with the stock sound is too bright and too forward in the upper mids for my taste. Note that if we are not happy with the provided green and blue nozzles, we can easily do our own mods on the white nozzle. This is why it was provided.BURST RESPONSE AND BASS QUALITY Do I think the bass quality on the same level at the legendary Sony EX1000's? From memory not quite. However, I no longer hear the bass quality as a possible liability as with the FD01. While not the bestest, the bass is solid and something I cannot fathom as a weakness. Texture rendition is better than the Campfire Audio DDs, but speed isn't as fast. Traditional DD sound in that sense. The Campfire Audio DDs could be said to sound like a hybrid between BA and DD tech (the distortion characteristics bare this out somewhat - another topic for discussion.)
