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.
Bluetooth headphones are not modernity, they should of course be an option, but increasingly they are the only game in town. Wired is still king for loads of things, not the least of which is reliability.
You wanna know how many times my wired Sennheiser’s have been unable to put music in my ear holes? Never. They always work. Care to guess how many wireless headphones have been able to provide sound every time I’ve wanted it without delay or failure? None. I’ve owned more than 2 dozen wireless this, that, and the other, headphones & earbuds, and none of them have been even a shadow of the reliability offered by my old wired headphones. Which is to say nothing of the fact that the wired experience usually sounds better (Still don’t think you can get any comfortable phat 600ohm monster cans that don’t have a wire) and has no issues with making sound when you’re in a space that is saturating the 2.4Ghz band (my Costco is usually so full of idiots on Bluetooth that you can’t get a reliable experience for anything from any wireless audio device.)
You seem to think it’s “backwards rhetoric” to want a feature that will never be offered in a wireless setup, and that’s just fucked man. There are a wealth of reasons why wireless does not fully replace wired. It’s why anything that doesn’t have to move generally gets a fixed connection, it’s just more reliable and often more efficient. That’s not backwards, it’s just a priority that you don’t value above others. If landlines or floppy disks offered any advantages over anything else they’d still be around today (and arguably they are in some limited niches,) but the replacements for those technologies have had no downsides against their replacements while wireless tech still has some significant downsides (again, maybe you don’t weight the pros and cons the same, so this may not apply to you) against the technology they are meant to replace, and will likely never see 100% capture of their role as a result.
TL;DR: Stop trying to frame this as some sort of crusade against the future, there are legit cases where wired is just better than wireless.
I hope you enjoyed typing all that out because I’m not reading it
