2 headphone jacks is definitely a choice. I wonder if there's at least one use case for it in 2024 though

It's aimed strictly at audiophiles. The extra jack is a 4.4mm jack that's more common in things like DACs.

An example:

Pair a phone like this with a pair of Sennheiser's and a bunch of FLAC files and you might have a really good time.

Oh so the jacks are different? Ok then. I thought the other sizes are dead or only used in niche $100k+ equipment

No I’ve got a $70 usb/bluetooth DAC w 3.5 and 2.5 jacks

but not 4.4mm which is apparently what the specialty jack on this phone is

Second sentence:

It has a 4.4mm headphone jack to go with the more conventional 3.5mm type.

4.4mm is for balanced audio output. This audience for this device is audiophiles.

Well idk anything about audiophile stuff. I know I can't afford to even look at such tech lol

You'd be surprised. Plenty of great in ear monitors that are sub $100 and use balanced 4.4mm jacks.

What is an in ear monitor? Is it like a medical device?

It's only a fancy name for speaker/headphones which make them sound more professionally, there's a chance but no guarantee that they are tuned more neutral in sound
