• Be sure to read the connected device’s user manual before use.
• Audio-Technica will not be liable in any way for any loss of data in the unlikely event that such losses should
occur while using the product.
• On public transportation or in other public places, keep the volume low so as not to disturb other people.
• Minimize the volume on your device before connecting the product.
• When using the product in a dry environment, you may feel a tingling sensation in your ears. This is caused by
static electricity accumulated on your body, not by product malfunction.

• Do not store the product in direct sunlight, near heating devices, or in hot, humid, or dusty places. Additionally,
do not allow the product to get wet.
• When the product is used for a long time, the product may become discolored due to ultraviolet light (especially
direct sunlight) and wear.
• If the product is placed in a bag while the USB charging cable is still connected, the USB charging cable may
become caught, severed, or broken.
• Make sure to hold the plug when connecting and disconnecting the USB charging cable. The USB charging
cable may become severed or an accident may occur if you pull on the cable itself.
• When you are not using the USB charging cable, disconnect it from the product.
• Do not charge the battery if the terminal of the USB charging cable is bent, loose, or damaged. Doing so may
cause heat generation, smoke emission, fire or electric shock.
• The magnetic clasp contains magnets. Do not bring a magnetic card close to the magnetic clasp. The card’s
magnetism may change and become unusable.
• Do not pull the magnetic clasp hard when attaching/removing it or adjusting the position. Doing so may damage
the cord.
• This product can be used to talk on the phone only when using a mobile telephone network. Support for
telephony apps that use a mobile data network is not guaranteed.
• If you use the product near an electronic device or transmitter (such as a mobile phone) which is not connected
with the product, unwanted noise may be heard. In this case, move the product away from the electronic device
or transmitter.
• If you use the product near a TV or radio antenna, noise may be seen or heard in the television or radio signal. In
this case, move the product away from the TV or radio antenna.
• To protect the built-in rechargeable battery, charge it at least once every 6 months. If too much time passes
between charges, the life of the rechargeable battery may be reduced, or the rechargeable battery may no longer
be able to be charged.
• Do not charge the battery when the battery jack or USB charging cable is wet. Corrosion of the battery jack or
USB charging cable may cause damage such as heat generation, smoke emission, fire, or electric shock.
• Charge the product in a well-ventilated place (10 to 35°C (50 to 95°F)) away from direct sunlight. Otherwise, the
battery may deteriorate, possibly resulting in shorter periods of continuous use or may fail to charge.
• If the product is wet with sweat, wipe off any moisture with a dry cloth before charging.
• Close the USB cap firmly after charging the product. Sweat or water may cause malfunction.

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). 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.
• 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.
