Devialet’s Gemini wireless buds are truly eccentric

The earbuds themselves are good for roughly six hours of action, while the case holds a further four full charges. An all-in battery life of 30 hours or so isn’t to be sneezed at - but neither is it the sort of eye-popping number that Devialet normally shoots for. Recharging can be achieved either via the case’s USB-C input or any Qi-certified charging pad.
