My phone doesn't have a headphone jack but even before they started disappearing I rarely used them anyway, much prefer wireless
I'm of the probably unpopular opinion around here that the less cables and IO I need the better, will often transfer large files over lan on WiFi rather than plug in because often in the time I've found a cable, plugged in, set the right USB mode, found the file on my phone's filesystem and transferred it the slightly longer wireless transfer would be done
Have a ThinkPad which has a ton of IO, but I think a couple thunderbolt/PD ports, a usb port and maybe an ethernet port if you do lots of fiddling with networking are plenty
Oh micro SD on the inside of phones too someone else made a point about that but that's more an upgradability/maintainability thing imo
A lot of phones are still limited to USB 2.0 speeds anyway and wireless won't be all that much slower and could potentially be faster.
Not supporting microSD annoys me a lot too. Especially on some phones that still have a dual SIM slot but don't support microSD on one of them. It's not even space at that point.
I do totally agree with your wireless mentality, i do the same with my mouse, keyboard, xbox controller, etc.
However, when it comes to headphone audio, i will always prefer wired, mainly for the better audio quality.
But... i have tried various bluetooth headphones in the past, and while the audio quality is decent enough, but everything else falls apart:
Battery won't even last 3 hours, and the battery meter on the phone is always wrong, (and i really don't want to keep an eye on the battery of THE device that makes everyday life bearable).
The buds themselves are either uncomfortable or fall too easily.
I went farther than 3 meters? Too bad, connection lost!
This is entirely dependant on what kind of headphones you buy though, if you buy nice ones they work just as well as wired
My over-ear headphones last a day of constant use and have a hot swappable backup battery (they also have a receiver for my PC) and can go anywhere in my flat with them without it cutting out
Earbuds I've got last most of a day and have a charging case that lasts weeks, similar range to the over ear ones
Both of which are very good sound quality (though the over ear ones are better when using 2.4ghz rather than Bluetooth), the same or better better than wired ones I've had before of similar price
If you're looking for good wireless buds try jabra elite 65t, those are the ones I've been using though they're a few generations behind at this point
