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.
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), 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 product if water or foreign matter is inside the battery jack or USB charging cable. Doing so may
cause corrosion, heat generation, smoke, fire, or other malfunction or electric shock in the battery jack or USB
charging cable.
Charge the product in a well-ventilated place (10 to 35°C (50 to 95°F)) away from direct sunlight. Otherwise, the

About pairing
When connecting a new Bluetooth device, you need to pair it with the product. Once the Bluetooth device and the
product are paired, you do not need to pair them again. The product supports multipairing, in which a connection history
is saved. However, in the following cases you will need to pair again even if the Bluetooth device was paired once:
If the product is deleted from the Bluetooth device’s connection history.
If the product is sent out for repair.
If the product is reset.
Multipoint function
The product supports multipoint, which allows two Bluetooth devices to be connected at the same time. While you are
listening to music with one device, you can answer a call that comes in from the other device. It is convenient if you have
two smartphones, for example.
Audio-Technica does not guarantee the operation of all combinations of Bluetooth devices.
Connecting using multipoint
1Pair with the first Bluetooth device.
2After pairing with the first device, turn off its Bluetooth feature.
3Pair with the second Bluetooth device.
4Turn on the Bluetooth feature of the first Bluetooth device.
If the product does not connect, restart its power.
Up to two Bluetooth devices can be connected at the same time with multipoint. To connect a third
Bluetooth device, disconnect one of the connected devices.
