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.
My hot take: does it matter? How often do people actually need to replace earbud batteries? I’m guessing it’s almost never.
Every 2-3 years in my experience, I’m on my 5th or 6th wireless headset in the last decade, and most of those were replaced because the battery life went to shit. And I’ve tried multiple brands with no material differences in overall life, but I also use mine throughout the day every day and regularly wear them until I’m forced to charge them.
If you don’t have a chance, or it’s made difficult by the design, few people will do it.But if it’s easy, maybe more people will do it. Show people a better alternative and some will take it. If the path is good, more will take it. That’s how you change the world.
Every earbud I had broke at least once during their warranty period. My linkbuds S recently broke the third time. Only one of my issues was battery related, but its still nice to have the option to use them after the warranty ends.
