With completely wireless earbuds, the rule is: when the battery fails, they have to be disposed of. Not so with the Fairbuds, that allow you to replace batteries in just a few seconds. Combined with a repairable design, the earbuds should therefore have an extremely long lifetime.
No ones disputing that wireless isn’t useful. But its not harming anyone to have a device both have a jack and bluetooth, the way it was for nearly 2 decades without any complaint.
Just because it was a way before doesn’t mean it’s good now.
I love my wired cans but your argument is a bad one.
More options is always better.
There was no reason to remove them back then and there is no reason to remove them now.
