• Do not cover the product with a cloth to avoid fire or injury by overheating.

• Follow applicable laws regarding mobile phone and headphone use if using headphones while driving.

• Do not use the product in places where the inability to hear ambient sound presents a serious risk (such as at railroad crossings, train stations, and construction sites).

• The product effectively shields external sound, so you may not hear sound around you clearly while wearing the product. Adjust the volume to a level where you can still hear background sound and monitor the area around you while listening to music.

About water-resistant (drip-proof) performance

• The water-resistant (drip-proof) specification of this product applies only to the headphones, not the charging case.

• 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).

• The water-resistant (drip-proof) performance is designed to protect the headphones if they get wet from rain, etc. (equivalent to IPX2). JIS/IEC protection grade IPX2 means that the headphones are protected against water droplets falling from above at a 15-degree angle. The headphones cannot be used in hot and humid places, such as bathrooms.

• The headphones are not waterproof. Submerging them in water may cause damage.
