Yeah, I know how they differ, and I can easily see how misconnections could occur depending on the tolerances of the jack. If physical connections were bridged, reversed, or shorted, I could imagine the effects being audible: hum, phasing issues, unstable connections, etc. However, I've occasionally used TRRS plugs (on, say, Apple earbuds) in TRS jacks for years, and have never experienced any dramatic, or even detectable, undesirable side effects. Just plain old stereo audio.
Yet, the third -- not the first, nor the second, over several years -- Schiit headphone amp that I recently acquired, in this case a recent Magni Heresy, came with a big ol' warning insert about the incompatibility of TRRS plugs with TRS jacks, and a link to an adaptor that they'd be happy to sell me. Now, of course, one could argue that they just want to sell adaptors, but it's five bucks, so I doubt it's a lucrative line for them; thus I'm guessing their pitch is rooted in a legitimate concern.
So ... what are the "problems" that remain undefined by this dire warning insert? Am I simply deaf to the implications, and thus have never noticed the horror I'm inflicting upon my ears by doing so? Are the potential problems with this combination rare enough that I've simply never encountered them? Is there something different about the later-production Heresy which makes it more susceptible to misbehavior when subjected to a TRRS-equipped peripheral than was the original, late 2019 Heresy?
I must know.
