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.
A friend of mine has a set of them at work and they work well in our noisy environment - machine shop.
The rule for earbuds is that you can only have one in so the bone conduction are gaining popularity at work.
I wish they fit in my motorcycle helmet. My earbuds fall out all the time when I take my helmet off.
I can use them everywhere. Except my whole subway ride…
