What does IPX4 mean?
IPX4 rating means that the headphones are protected from a splash of water in any direction.  A water-seal rating of IPX4, which ensures the instrument will show no adverse damage even if exposed to water splashing from any direction. However, the instrument is not water-proof, so it should never be washed with water or left immersed in water.

Our wireless earphone product line is well made with IPX4 waterproof rating.
