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.
And get caught on everything.
I can’t be bothered with the inconvenience of wires. Bluetooth quality is good enough for what I need it for, and the convenience of simply putting them on gives me sound is hard to beat.
I have a pair of noise-canceling Bluetooth headphones (not buds) from 2008 that still work. Battery life isn’t what it was, but whatever - they work fine for how I use them (as one pair of several). I could replace the battery if I felt like it, just not worth the effort.
But I get that some people prefer the wired for their use-case.
