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
There are still phones that have it. Sometimes even pretty good ones. It's just that they are not advertised so heavily. I recently learned about HTC U23 or 24 or something. Now I feel dumb because I never bothered to check because I always thought all good phones don't offer headphone jacks anymore.
