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’ve used passive noise isolation earbuds that work better than any ANC. This one time I took them off after a long flight, only to realize that a toddler was crying behind me.

Yeah, idk why people are downvoting you so hard. There are some seriously good passive noise cancellation buds out there. Kind of insane when you actually try them.
