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
What device? On mine it just switches between outputs.
Both Samsung phones I’ve had do it. And I know iPhone can. It’s a really great feature. My wife and I use it to listen to books together
