> I bought myself for just a few euro a Bluetooth DAC (a FiiO) that had superior sound quality to any phone’s audio-out that I had ever used.
I hate the 3.5'' jack myself (see below), but I can already tell you that mentioning some unscientific definition of "superior sound quality" that likely no one amongst us is humanly able to distinguish is not going to win any minds over. Proponents of 3.5'' like it because it is ridiculously simple to use, intuitive, cheap, doesn't have a lot of things that can go wrong (e.g. no batteries) and despite that is overall effective.
The reason I dislike 3.5'' is because the _socket_ part (i.e. the part on the expensive device) wears out very quickly, becoming fragile and generating distracting artifacts even with slight cable pulls/movements, as the springs in the connector start to fail. This annoys me to no end, much more than any issues with other interfaces.
Talking about “superior sound quality” in the context of mobile phones isn’t controversial, it’s not like a home-stereo audiophile snake oil debate. It is well known that DACs are an area where mid-range and low-end phone makers have cut corners, choosing chips that are quite flawed for anyone who uses their phone to listen to music where pristine sound quality is valued.
The elephant in the room for me is "microphonics" or the noise piped to your head via the wire any time anything touches it.
You demand higher quality, yet don't care about the loud noise created with every small movement of your body? I have heard this dismissed before as "doesn't bother me" and it's hardly ever mentioned in discussions about good audio vs Bluetooth.
I'm bewildered why wireless audio isn't praised for completely eliminating this source of noise that plagues every wired headphone, earbud, and IEM.
