9. Is the UTWS5 waterproof?

Both the mesh of the microphones and the button position was added with a water-resistant sound-permeable cotton. There is no exposed metal touchpoint on the ear hooks in the UTWS5 2025 comparing with the previous version. The possibility of metal touchpoint breaking down quickly due to sweat corrosion, resulting in the inability to charge or disconnect from the phone will be reduced. And the joint position used glue. The overall design is IPX4-grade water-resistant. Therefore, it is freed from water and sweat.
