Just replace my perfectly good $200 headphones that work in my (old) phone, my Switch, my 3DS, my laptop, my iPod, and my work phone.
It's so simple!
Seriously, even if you don't use it, why are you so against others having the choice? The headphone *jack was the standard for decades for a reason. If my phone is low on power, I'd like to be able to charge it without disconnecting my music/podcasts...
