after the full charge, but that depends on personal use- I used it in the bathtub and its still working so I guess its waterproof for my daily routine. The microphone is horrible and the sound quality is the same as twenty dollar ones. That first step out of bed in the morning is always the worst. En este aspecto una pasada, es como si tuvieras un noticiario personalizado en todo momento. I thought it was worth 4 stars though when i had just one until I realized after doing more listening that its actually a very honest and accurate speaker, and if you dont mind that it only extends to about 15khz, (totally fine for me), its a glorious sound for the price. To turn them off put hem back in the case. I over probate and have flat feet. Very comfortable and pretty. But it doesnt exactly go to plan. I would recommend these slippers ,very comfy looking.
