[OnePlus 9 Pro] VelosterM14:
I get it... headphone jack may not be for everybody. Me, well let's just say that I've got my reasons. For a good long while I was chained to a desk in corporate IT cubeworld, surrounded by noisy people. I needed headphones and a good collection of music to drown out the.... lack of productivity generally going on around me. It was also hard to be very productive in my line of work with music cranked up in my ears, but at least I got to pick the noise, which was never the case there around my desk at the office.

Sadly, in my searching tonight for a USB-C headphone jack adapter, I've not seen one yet with a built-in charger input that you can do both simultaneously (charge AND listen to music at the same time -- or charge and participate in a call over the headset) on a OnePlus, although other brands seem to be able to. So if I ever do have to go back to cubeworld again (hopefully not), especially at the current peanut dispenser, this will surely bite me in hindermost parts at some point, ie, needing to charge AND keep the music going at the same time. Or face the certain peril of my phone having to recharge while the next bagel party is planned or other mindless, non-productive blibber blabber occurs around me...

So I don't see buying a USB-C to headphone adapter as a very good solution. I did find one that looks nice and doesn't cost very much (like a good shrubbery) which I ordered, but I'll have to settle for not being able to charge simultaneously. I'll admit to being a little salty about that.

Musicians are another example of a group of people who tend to prefer wired over bluetooth/wireless monitors/headphones for pretty good reason. Especially drummers. When even what you are hearing in your ears lags behind realtime...

So it has taken me a long time to settle on a phone, lack of headphone jack being among the main reasons. It's funny at least to me how they can justify the real estate for more and more camera eyes and sensors (but still fall so short of truly breathtaking camera performance) -- but on flagship models their marketing people also want you to believe are a pro audio platform, you either have to have bluetooth audio or buy an adapter, because they just don't have the room (or the market demand?) for a 3.5mm headphone jack.

I'm perfectly OK with people not seeing things my way, but in my book, bluetooth cans/IEM's/earbuds are also just something else that have to be recharged when the battery is drained. The marketing people may tell you cords are tangly and a hassle for joggers and other people with active lifestyles -- my take on that is a little diferent. At least when the wired earbuds fall out of your ears, they are still attached to something you can probably grab before they get away from you. :)

The SD card slot, well it's another thing related to having a decent music collection on my phone and room for backups and various root/mod/etc things handy without using up the device's storage. But with 256GB I will survive. I would not have been able to suffer 128GB though.

These little obsoletions are the sorts of things they call "progress" these days. I tend to have pretty good reasons for knowing what I want. It's just getting harder and harder to find anymore. I'm pretty used to the world going the other way though. It's just really been picking up the pace lately.

But at least I was able to find something well supported by LineageOS and by what I've been reading around, has decent moddability and tools etc.

Hopefully these will last a good long time.

EDIT/PS: I sat down and compared the radio band support of the 9 Pro and 10 Pro, along with coverage bands my current carrier TMO and the only other one we would ever consider switching to supports (if TMO really goes bad somehow, VZW would be most likely escape route but we are not really big VZW fans after many years of customer abuse, why we switched to TMO) . There's not much of difference between 9/10 for bands support really but for those times we do go out and about, those mmWave bands the 9 Pro supports would be useful, and are used/supported by both carriers we care about in our area.
