The problem with all wearables is that clothing generally lasts longer than the tech. I’ve had the same pair of sunglasses for almost a decade. I have jackets and other articles of clothing that are quite a bit older than that. Throw a battery in any of those things and the lifespan of it immediately drops to a fraction of what it would be without. I guess you could argue this is by design—clothing manufacturers want you to get a new set of their items every few years like you might with an Apple Watch. Still, the value add needs to be high enough to justify a much shorter lifespan. Apple pulled that off, but I doubt others can.
