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
A Bluetooth dongle still requires batteries that would otherwise not be needed.
You are just moving the problem.
Absolutely. But I’d rather deal with charging the battery in the adapter than risking breaking my headphone cable or my phone. So for me the problem is worth moving.
