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 use both wireless and wired, depending on what I’m doing. The earbuds fall out when I’m exercising, but have better call-quality because of the noise canceling.
And I use wired for chatting, when playing games with friends on playstation. And I still have an ipod I use occasionally… so I just kinda have both.
I prefer to have a headphone jack on my phone, but I have a dongle adapter for usb-c, if I want to use my wired ones. I would just prefer not to use the adapter if I didn’t need to, because I’ve already had issues with my phone’s charging port trying to crap-out on me. The charging port isn’t as robust, and you do lose some quality with the dongle. I deal with it just fine; but a headphone jack on a phone might tip me towards purchasing that one, if I were looking to buy a new phone. It depends for me, but it’s not the end of the world, just an inconvenience that could easily be avoided
