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
These jacks are still in every other audio device. They were removed from phones to force BT usage, which Google needs for their profiling telemetry network and Apple for their Find my Device thing. God forbid someone turns BT off or even decides they would prefer a phone without BT entirely. There is no other reason and how people prefer to listen to music has nothing to do with the subject.
Doubt there is any conspiracy. Headphone jack was probably removed to cut cost since wireless earbuds were becoming popular and majority of users did not mind. It annoyed me at first as well, but once I went with BT earbuds and headset, I cannot imagine going back to wired except when stationary on PC. Battery life is 30 or so hours and I do not thing I have ever had problems with connection.
Only thing that worries me is that your earbuds probably are an e-waste once battery no longer can hold a charge. That said my current earbuds are basically destroyed even though their battery still is fine.
There were cut because they make a lot of money selling wireless earbuds.
