The Moondrop MIAD 01 is one of the most distinctive Android devices of 2024 thus far. It has a 4.4mm headphone jack to go with the more conventional 3.5mm type. Furthermore, it seems it might be as appealing to teardown enthusiasts as well as audiophiles, and may, therefore, also be easier to repair than most modern smartphones.
In this situation I don’t think it will at all.
I don’t think that balanced vs unbalanced is actually electromagnetically that different in this particular configuration (see my edit at the end of above). Things like where the wire is sitting on your body and what pose you are in will probably affect RF noise pickup levels on the headphone wires much more than changing between bal & unbal signalling.
I didn’t get into near-field and far-field effects. I’m not sure that it really matters here, but I might be wrong.
I was going off the few pages I read, including the one I linked. I’m far from an expert in this realm, so, really, I don’t have any substantial argument for or against what either of us are saying. However, filmography, and the related foley artistry, has always intrigued, and I have learned from experience the differences between using a standard jack and an XLR, and I can say that the sound is vastly cleaner with XLR (at least on a set). The secondary jack on this phone seems to be to XLR what USB-microB is to USB-A (again, going off what I’ve read). You do make a lot of sense, though, in your posts, so I may be flat wrong here haha
Your experiences were correct, don’t doubt them. That would have been ground-referenced equipment, ie plugged into wires that eventually join a wall. RF interference would interact with that quite differently, unbal vs bal would be quite different.
