We used to have earbuds that don't need to be charged because they had a headphone jack, didn't get lost so easily because they had a cord attached to a headphone jack, never lost the bluetooth connection because they had a headphone jack, and they cost less because they had a headphone jack. https://bsky.app/profile/daisyfm.bsky.social/post/3l3mfjc6sn62k
Or not being up to par with Bluetooth. Seriously, you would still see Bluetooth everywhere even if you had a jack. I prefer Bluetooth over cabled alternatives even now with a phone that has it, so does my brother my sister my friends and family. I'm also sorry to say this but even my grandparents have preferred Bluetooth
Good for you. Clearly not the case for everyone given the thread. And considering including a jack wouldn't impact you all anyway, Im not sure why you care.
I'm sure bluetooth is fine, it's just that unfortunately most didn't get much of a choice in the matter.
