About the Active Noise Cancellation Function

The product is designed to use its built-in microphone to pick up ambient noise (vehicle noise, air conditioner noise, etc.) and cancel that noise by producing negative-phase sound. This results in a reduction in the sound of your surroundings.

• The product's noise cancellation function is primarily effective against noise 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 effect of noise cancellation.
• Depending on how you wear the product, the noise cancellation effect may vary or a beeping sound (whistle) may occur. In such cases, remove the product and re-insert it correctly.
• To maximize the noise cancellation effect, select eartips that offer the best acoustic isolation for each side to block surrounding sound, and insert the headphones into your ears correctly.
• When using the product on a train or in a vehicle, such as a bus or truck, noise may be heard depending on the condition of the tracks or road.

If the Product Does Not Connect to a Device

If pairing cannot be canceled or does not occur correctly, you can use forced pairing mode to perform pairing again.

1. About 5 seconds after placing both headphones (L (left) and R (right) sides) in the charging case (with remaining battery), touch and hold (for about 6 seconds) the touch sensors of both headphones.
2. When the indicator lights on both headphones illuminate red, remove the headphones from the charging case.

The product will enter "Device Search" (pairing mode) and you can pair it with the 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.

1. About 5 seconds after placing both headphones (L (left) and R (right) sides) in the charging case (with remaining battery), tap the touch sensors of both headphones twice in succession.
2. Ensure the indicator lights on both headphones flash white, then touch and hold (for at least 6 seconds) the touch sensors of both headphones while they are in the charging case.

Ensure the indicator lights on both headphones illuminate red and then turn white before releasing your fingers. The reset is complete.

3. Remove the product from the list of registered devices on your Bluetooth device.
4. Remove the headphones from the charging case again and perform pairing.

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

About Water Resistance (Drip-Proof) Performance
