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
So I just leave my adapter attached to my earbuds.... You know how you used to have earbuds that didn't have silicone tips? Treat the dongle like a silicone tip. It's just a part of the earbuds now.
Depending on how much you hate the lack of 3.5mm, $9 to fix that problem is a pittance.
I know I'd pay $9 more for a phone if it had 3.5mm. even if you had to buy multiple adapters for different earbuds, I'd happily pay $50 more for a 3.5mm on my phone, and this should generally be equivalent.
