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
They also didn't add an extra layer of compression between the player and your ears - because they had a fucking headphone jack and wires that could transmit audio data without compression.
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.
