• The ANC effect may vary depending on how you put the unit or buzzing (squeaking) may occur. In this case, remove the unit and then wear it again.
• The ANC function is mainly effective for low-frequency noise. The noise can be reduced, but it can not be completely eliminated.
• The mobile phone may cause interference and noise to the unit. If this happens, place the unit away from the mobile phone.
• Do not cover the microphone of this unit with your hand, the ANC function may not function properly, or buzzing may occur (squeak).
