- Usage issue -
For ANC headphones some wrong wearing ways may cause strange noise in ANC mode.
1) Wrong wearing ways: Pressing hard on the ear pads housing, metal earrings covering the noise cancelling mic, removing the ear cushions, moving head or walking quickly.
Depending on how you wear the headphones, the noise canceling effect may vary or a beeping sound (howling) may occur. In these cases, take off the headphones and put them on again.
2) The noise canceling effect may not be pronounced in a VERY QUIET environment, or some white noise may be heard.
If you confirm the headphones usage is right/ the Bluetooth operational range/Wired audio cable is fine, but the noise still exists, please feel free to contact firstname.lastname@example.org to kick off the replacement process.
