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.
Unrelated, but how do you tolerate that length of commute every day? I’d last 3 days before either looking for a new job or a new house.
Well… It’s not a commute that I need to do every day. Also I can (to some extent) work on that commute as the majority of it is on an inter-urban train. Timeboxing tasks to 30 mins or an hour can be quite productive. That said, having decent music and or noise blocking configured for your environment helps a lot. I highly recommend these guys - I have their full app and being able to dial just the right frequencies to deal with whatever is bugging you is amazing…

That said, without my device and quality headphones/iem I wouldn’t be able to tolerate it.
