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
In ancient times, the wire also acted as antenna to pick up FM radio
The copper age…
It still does if you buy a phone with a headphone jack and avoid shitty companies that disable the FM tuner.
