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 most expensive earbuds were $75.
At $150, I’d rather buy multiple “lesser” ear buds and not worry about battery lifespan.
I have 2 pairs of hang-on-ear type I use for the gym/exercise, that were $35 each. That’s less than 1/4 the price of these.
Then these aren’t for you and that’s fine. You don’t value what they offer, and you’re not obligated to buy them. Some of us do.
Sorry, what? They are obliged to buy them, if not today, they will be when their phone stops working and they have to buy a new one, because that won’t have a jack connector.
Except of course if they don’t use a smartphone.
