About water-resistant (drip-proof) performance
- The water-resistant (drip-proof) performance is designed to protect the headphones if they get wet from rain, etc. (equivalent to IPX2).

The headphones cannot be used in hot and humid places, such as bathrooms.
- Although the product has water-resistant (drip-proof) capabilities equivalent to IPX2, the part where the sound comes from is not water-resistant (drip-proof).
- Make sure to close the USB cap completely when using the product to maintain water-resistant (drip-proof). If the USB cap is not closed completely, water may enter inside.
- The headphones are not waterproof. Submerging them in water may cause damage.
