  • The product may not operate correctly if the touch sensor is dirty from sweat. Remove any 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 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.

For a more comfortable Bluetooth communication experience

The effective communication range of this product varies depending on obstructions and radio wave conditions.

For a more enjoyable experience, please use the product as close as possible to the Bluetooth device. To minimize noise and sound disruptions, avoid placing your body or other obstacles between the product’s antenna (L side) and the Bluetooth device.
