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...

This level of noise results in a measured SNR of -77.9 dB @ 0.775 Vrms into 300 or 30 ohms, while the rated SNR is -97 dB @ 1 Vrms into 45 ohms. It also contributes to the poor linearity of the amplifier.
Atomicbob tried to improve on the noise level by using his (very good and expensive) LPS, but even then it resulted in a SNR of -90 dB, still almost 10x under spec.
I've raised this issue with the author (and @CEE_TEE) and have not gotten a response from anyone yet. Because the level of noise measured is so high and downstream metrics differ so much from published specs, there is a chance of that the measured unit was defective (far less of the chance that Atomicbob didn't know what he was doing).
I am taking the "wait for a response from @CEE_TEE" before purchasing.
EDIT: The response is "you're dumb to complain because people like its sound. There's nothing wrong with advertising SNR at 100x lower than actual SNR." Wow.
EDIT2: After much consternation all around, Atomicbob has new measurements which show that tube was defective. The MCTH performs to spec.
You come to me with a brand of frozen chicken nuggets that I, a food expert, reviewed. On the product box, it says "made with real chunks of white meat chicken," yet in my review I clearly show how these nuggets are made from mechanically separated chicken. I don't explain it further because there were a lot of things to cover in that review, but I do add some highlights, all of which are positive remarks about how the product tastes good. And, it does taste good.
You, a budding chicken nugget enthusiast and consumer, is interested in this chicken product, but you're worried about the mismatch of what the packaging says and what I said in my review. You're concerned because you've seen my other reviews, and they've convinced you that I am a reliable source of expertise for this sort of information. You trust me. You respect my opinion. So, what do you do? You raise the issue with me and ask for my advice. You think, maybe he reviewed a bad batch of nuggets? Maybe there was something overlooked? Surely this can be cleared up.
My response to you is: "Focusing on this specific detail on the product packaging will mislead you to false conclusions. Can you even taste the difference anyway? Here's a sample for you to taste. I personally enjoy these nuggets, they have excellent kick and balance of flavor."
You feel insulted because in your mind, the issue at hand isn't ultimately how good the chicken tastes, but the fact that you're fairly sure mechanically separated chicken strays too far from being real chunks of white meat chicken. Yet your trusted expert just said, "Can you taste the difference anyway?" implying that if the answer is "No", then there is no issue at hand. (???)
You're triggered, and after some back and forth, I eventually tell you, "When it comes to chicken nuggets, industry rules allow for wider variance on what can be defined as real chunks of white meat chicken, and that can include mechanically separated white meat chicken."
That's the only signal that came out of the noise, the bit of expert information you were missing, whether you agree with it or not. You wonder why I didn't say that in the first place, instead of predicating the relevancy of inaccurate advertising on the ultimate, holistic taste.
