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.
I still have 200 euro wired in ear headphones that are my favorite pair so I need to 3,5mm port. But I never got the loud commotion over the disappearance of the port, because you can easily use a 3,5mm to USB-c cable. Having said that,I do still appreciate such a port in my phone because sometimes I forget to take the cable with me or I lose it.
