Notes on use
• 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 subject the product to strong impact.
• 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.
• 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.
• 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.
• When you are not using the product, store it in the included case.
• 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.
• The volume of the product differs depending on if the noisecancelling function is on or off.
• Operating with a sharp-tipped object, such as a ballpoint pen or pencil, may not only result in incorrect operation, but could also damage or break the touch panel.
• Do not touch the touch panel with the very tip of your finger.
Doing so may cause your fingernail to break.
• If the product does not operate at all or as intended when touched, check to make sure that your other fingers, parts of your hand, or clothing are not in contact with the product when touching. Confirm the touching range of the touch panel with the user manual before operating its wide range by touching. Also, the product may not operate correctly if you are wearing gloves or if your fingertips are dry.
• The product may not operate correctly if the touch panel is dirty from sweat. Remove any dirt before operating the product.
• The provided airplane adapter may not be compatible with certain types of aircraft devices.
• Do not use the product when the use of electronic devices is prohibited on the airplane, or when the use of personal headphones with the aircraft's audio service is prohibited.
About the active noise-cancelling function
The product is designed to use its built-in microphone to pick up noise from the surrounding environment (noise from vehicles, noise from air conditioners, etc.) and to cancel out that noise by producing sounds in negative phase. This results in a reduction in the sounds in your environment.
• The product’s noise-cancelling function mainly reduces noises of 300 Hz or lower. Because of this, it has almost no effect on noises above that frequency (ringtones, speaking voices, etc.).
• Not all sounds are cancelled.
• Depending on the type of noise (or in quiet locations), you may not notice the noise-cancelling effect.
• There is a “humming” sound when you turn on the noise-cancelling function. This is the sound of the noise-cancelling function operating; it is not a malfunction.
• The noise-cancelling effect may vary or a bleep (howling) may occur depending on how you wear the product. In these cases, take off the product and put it on again correctly.
• When you use the product in a train or a car such as bus or truck, noise may be heard depending on rail/street conditions.

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 multi-pairing, 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.
• When switching to a Bluetooth device, you may not be able to pair because the previously connected Bluetooth device cannot be disconnected. In such cases, long touch (10 seconds) the upper and center parts of the touch panel as shown in the figure. The product will switch to the “searching for devices” state and you will be able to pair with your desired Bluetooth device.

Cleaning
Get into the habit of regularly cleaning the product to ensure that it will last for a long time. Do not use alcohol, paint thinners, or other solvents for cleaning purposes.
• To clean, wipe with a dry cloth.
• Wipe away any perspiration or dirt from the cable with a dry cloth immediately after use. Failure to clean the cable may cause it to deteriorate and harden over time, resulting in malfunction.
• Wipe the plug with a dry cloth if dirty. If you use a dirty plug, you may hear distorted or skipping sound.
• Wipe away any dirt from the earpads and headband with a dry cloth. The colors may fade if sweat or water gets on the earpads and headband. In this case, we recommend that you wipe them with a dry cloth and let them dry in a shaded spot.
• If the product will not be used for an extended period of time, store it in a well-ventilated place free from high temperatures and humidity.
• The earpads are consumable parts. They degrade through storage and use, so replace them as early as possible.
For earpad replacement and other repairs, contact your local Audio-Technica dealer.
