The headphones they sell are actively the least disposable ones you can buy. That being said, it’s not the most sustainable way to listen to music. Imo, they removed it too make engineering the phone easier. If that means they can reduce the price from what it would have been and make the phone more repairable, then I’m happy for that compromise.

Have you owned a fairphone? From experience with my gf’s fp4, she has not had to keep sending it back in due to hardware issues. If it was such a big issue as you seem to think, they would have gone out of business with all the replacements they would need to do…
