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 never understood why people care so much for wireless charging. It’s less efficient, therefore you heat your device more which shortens the longevity of the battery, you charge slower, and if you move the device slightly, it won’t charge, therefore it’s less reliable (unless there is a magnet array like apple). Sure, it’s useful in a pinch, but is it really a make or break feature?
I never understood wireless charging either, you still can’t move your device around (well if we ignore the fact you can move it around somewhat with a cable). It requires a charging pad too, so it also takes up more space.
for earbuds it’s useful as many modern phones can share their battery to wirelessly charge another device, so you can top up your earbuds off of your phone while you’re out somewhere and not need to lug around a charger and cable.
For wirelessly charging phones, I agree the pad style chargers defeat a lot of the point, but I am a fan of the dock-style wireless chargers. I have one at my desk and can just glance at my phone to see notifications, and I have to set my phone somewhere anyways, so this lets me top up my phone without really thinking about it.
That’s the only benefit I can think of, the reverse charging on phones (which is very slow). They could add that feature to the usb port though. I mean the dock thing sounds alright I guess, but I just plug my phone in, then it’s charging on desk and in hand and it only needs to be in for like 30 mins and it’s full charged.
