5a is EoL so no headphone jack for you. This is a nonstarter for portable devices to me.
USB C to AUX adapters work for me.
Having a secure and up to date device should likely be more important
Flimsy awkward adapters + having to choose between charging or audio? But they had matching earbuds with irreplaceable batteries to sell…
Ugreen sells a dual adapter. I’m sure other make one too. Don’t choose, just have both.

As for flimsy, unless you get apple’s piece of crap, they are resonably durable. Headphone cables were never know for duarbilty either.
Lastly, just leave the adapter plugged into your headphones or aux cable.
I’ll agree, they are awkward and I do miss my headphone port, but the solution work around is not that deep.
