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 did not think people would perceive it like that, and didn’t realize the jack was phased out before bluetooth ear buds were a thing, as I myself had a phone with a headphone jack until at least a couple years later, and by the time I got a phone without a headphone jack, I didn’t need it anymore.
I for one have been very happy with wireless headphones because with my job, the wires would get caught on stuff too easily, or I had to run the wires through my shirt, and they barely had enough slack for me to turn my head while my phone was in my pocket. (and btw the job I have is that’s unsupervised where I can have an ear bud in while working)
