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
I remember getting horrible feedback in my car's stereo when I tried to simultaneously charge my mp3 player from the car's cigarette lighter adapter and run an aux cable. Somehow this resulted in a feedback loop that ruined the audio quality. I had to either charge or listen to music, not both.
