The thing is that Jack headphones are so ubiquitous. When you forget your plugs or the battery is dead you can just grab a wired set for 3 bucks.

Forgetting doesn't help with adaptors which aren't really standardized, especially the passive ones. And the active ones are expensive..

My work phone still has a jack plug. I don't use it much but the times I do use it I'm really in need of it because I don't have anything else to use.
