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

After both headphones (L (left) and R (right) sides) are placed in the charging case (with battery remaining) and the indicator lamps light, touch and hold (about 4 seconds) the touch sensors of both headphones.
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

Reset the product.

After both headphones (L (left) and R (right) sides) are placed in the charging case (with battery remaining) and the indicator lamps light, 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.
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.
Remove the product from the list of registered devices on your Bluetooth device, and perform pairing again.

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 headphones have water-resistant (drip-proof) capabilities equivalent to IPX4, 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 IPX4). JIS/IEC protection grade IPX4 means that the product is protected against exposure to flying water from all directions.
The headphones cannot be used underwater.
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.
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-Technical website.
