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.
People keep whining about this but honestly people who listen to music with wired headphonea are a small fraction of a 1%. And they probably have this data from their telemetry.
They are now a small fraction cause this trend is already 8 years old.
Don’t wanna be a whiner but wireless in ears never last long enough for me. I’m forced to stop using them after a while because they need to be charged. Even a 2 and a half phone call is enough to deplete them. This is a non existing problem with wired ones
