• When you are not using the USB charging cable, disconnect it from the charging case.
• When you are not using the product, store it in the included charging case.
• If you use eartips other than those included, the headphones may not fit into the charging case, or may not charge. Be sure to use the included eartips.
• When using the product, select the eartips that fit your ears best so the product can be worn securely.
• 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 radio antenna, noise may be seen or heard in the radio signal. In this case, move the product away from the 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.
• 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 headphones are wet, wipe them with a dry cloth before placing them in the charging case. The charging case is not water-resistant (drip-proof). Do not charge the product if the headphones are wet.
• The hear-through function of the product allows you to hear the sounds around you through the built-in microphone. Depending on the volume of the music being played back, the surrounding sounds may be difficult to hear. In this case, turn down the volume of the music.
• Depending on your surroundings, the ambient sounds may be difficult to hear even when using the product’s hear-through function. Do not use the product in places that are dangerous if you cannot hear the surrounding sounds, such as places with heavy traffic.
• Operate the touch sensor with one finger. Operating with a sharp-tipped object, such as a ballpoint pen or pencil, may result not only in incorrect operation, but also damage to the touch sensor.
• Do not touch the touch sensor with your fingertips. 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 items are not in contact when touching. Also, the product may not operate correctly if you are wearing gloves or if your fingertips are too dry. The product may not operate correctly if the touch sensor is dirty from sweat. Remove the dirt before operating the product.

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 is mainly effective against noises in the lower frequency range, but not all noises are cancelled.
• Depending on the type of noise (or in quiet locations), you may not notice the noise-cancelling effect.
• A slight humming sound may be heard when using the noise-cancelling function. This is a sound generated by the noise-cancelling function; 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 the  product in your ears again correctly.
• To maximize the noise-cancelling effect, select the eartips that offer the best sound insulation for each side to block surrounding sound, and insert the headphones into the ears correctly.
• When you use the product in a train or a vehicle such as bus or truck, noise may be heard depending on rail/street conditions.

If the product does not connect to a device A

If pairing cannot be cancelled or is not successful, you can use forced pairing mode to perform pairing again.

1. About 5 seconds after both headphones (L (left) and R (right) sides) are placed in the charging case (with battery remaining), touch and hold (about 4 seconds) the touch sensors of both headphones.
2. When the indicator lamps on both headphones light in orange, release your fingers and remove the headphones from the charging case.
   • The product will switch to the “searching for devices” (pairing mode) state and you will be able to pair with your desired Bluetooth device.
   • If the procedure cannot be completed as expected, remove the headphones from the charging case again and repeat the procedure from the beginning.

If the product operates abnormally B

Reset the product.

1. About 5 seconds after both headphones (L (left) and R (right) sides) are placed in the charging case (with battery remaining), touch and hold (about 10 seconds) the touch sensors of both headphones.
   • While touching and holding the touch sensors, the indicator lamps will light in orange once after about 4 seconds, but keep pressing and holding the touch sensors.
2. When the indicator lamps on both headphones start flashing in orange, release your fingers and remove the headphones from the charging case.
   • Reset is complete.
3. Remove the product from the list of registered devices on your Bluetooth device, and perform pairing again.

If the procedure cannot be completed as expected, remove the headphones from the charging case again and repeat the procedure from the beginning.

Waterproof and dustproof performance

• The waterproof performance of the product is designed to prevent the ingress of liquids from sweating during operation and simple washing (equivalent to IPX5). JIS/IEC protection grade IPX5 means that the earphones are protected against exposure to water jets. The earphones cannot be used in hot and humid places, such as bathrooms.
• The earphones are not completely waterproof. Do not intentionally submerge or use the earphones in water. Also, do not expose the earphones to liquids other than sweat and water (such as soapy water).
• The dustproof performance of the product is designed to prevent the ingress of dust and dirt (equivalent to IP5X). JIS/IEC protection grade IP5X means that the earphones are protected against the ingress of dust that would otherwise hinder operation.
• The waterproof and dustproof specifications of this product apply only to the earphones. The charging case is not waterproof or dustproof.
• Although the earphones have waterproof and dustproof capabilities equivalent to IP55, the part where the sound comes from is not waterproof or dustproof.
• The headphones may not function properly if they become wet. Wipe the headphones with a dry cloth, shake them multiple times to remove any excess water, and allow the headphones to dry thoroughly before use. For more information, refer to the user manual on the Audio-Technica website.

For a more comfortable Bluetooth communication experience
