Yes if they’ve lasted decades thats their job done. Now people are buying usb C headphones and there is no need to continue to support decades old standards. The ewaste from a pair of headphones is tiny so its not worth fretting over.
Also BT headphones last longer than 2 years. Mine are 1st gen samsung buds and going on 5 years at this point and still hold enough charge to listen to music during my work day. If im going to be using them all day I have 1 in and 1 charging in the case and then I can easily have music for 10+ hours on a 5 year old device. If I threw them away today I would consider them to have not been ewaste.
Cars have had bluetooth and usb on their radios for almost 20 years. Even older than that you can replace the stereo for like $30. My car is 2004 and i did a stereo replacement and i’ve got bluetooth, usb C and aux.
