Notes on use
• The waterproof performance of the product is designed to prevent the ingress of liquids from sweating and simple washing (equivalent
to IPX5).
• Although the product has waterproof capabilities equivalent to IPX5, there may be no sound or the sound may be difficult to hear if
water enters the headphones because the part where the sound comes from is not water-resistant.

sweat and water (such as soapy water).
• If dirt such as sweat or sand adheres to the product, wash it with normal temperature (10 to 35°C) fresh water or gentle-flowing tap
water instead of soapy water. Do not directly expose the “part where the sound comes from” to water (not water-resistant). For details
on removing dirt, refer to “Cleaning” (p.14).
• The product is not designed to be dampproof. Do not use the product in environments with high humidity (such as bathrooms or
