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
They’re not valid, they’re excuses which are provably wrong. Samsung will currently sell you a phone with a jack which is ip68 waterproof, has a milspec durability rating and it costs a whopping €250. So clearly the jack is not a design limitation in any of those ways.
