A few years ago I was on team keep the jack but at this point it's not as necessary. USB C headphones exist, wireless headphones have gotten quite good, and if you use one pair of 3.5mm headphones if you keep a dongle on it it's really not that inconvenient.
It's very off-brand for Fairphone to start selling non-repairable earbuds and then release a phone without a headphone jack. Fairphone bills itself as being fairer for its workers, its customers, and the planet. How is Fairphone being fair to either the customer or the planet if they're making wireless headphones the most convenient option? Wouldn't it be fairer to customers and the planet if customers could use the wired headphones that they already own? Plus, wireless headphones have an artificially short lifespan due to the batteries.
