6. Can UTWS1 waterproof both the water and sweat?

A: UTWS1 circuit board uses nano waterproof coating and waterproof glue. The rain and sweat during use will not damage to the earphone.
But for a better experience, we still recommend to keep it from the water and make it dry as soon as possible once it touches the water.If it is damaged by dropping into the water, we will not provide free warranty service.
