I must admit, I don’t get the wish for 3.5mm headphone jacks in 2025. Already six years ago, with a phone that actually still had a headphone jack, 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. With a Bluetooth DAC (or with any USB-C to 3.5mm converter that costs pennies) you can still use whatever wired headphones you want to use.

Physical keyboards were nice back in an era when the web welcomed longform text, and I miss my Nokia N900. Nowadays, though, the web ecosystem that one typically uses from a phone is a cesspool, and for serious things I’ll just use my real computer.

I have a similar FiiO gadget and it makes less sense for me than a direct wired connection to the phone. It's a relatively bulky device that needs to be charged way too often, also it reduces voice call quality (like any other BT Classic device).

I'm conflicted about this matter. I use a Bluetooth earpiece on my phone because it's more convenient: you can move around a room with the phone on a table, no pockets, and you can wear and unwear t-shirts and sweaters. When I can't find the x with the earpieces I plug in in a wired one.

On the other hand a wired headphone always work, had maybe better quality and almost surely a better latency. I use one of them when doing calls from my laptop.

Bluetooth wastes batteries / alter soubd.

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.
