Check the fit

ANC performance relies heavily on a good physical seal. If the fit is loose or there are gaps, ambient noise may enter and reduce the effectiveness of noise cancellation.

Ensure the ear cushions fit snugly against your head, especially around the edges where the ear cushions make contact with your skin.

Check the ANC status and level

Open the soundcore app and confirm that ANC mode is enabled. Make sure the noise cancellation level is set to an appropriate level for your environment.

3

Check the microphone opening

Make sure there is no dust or debris blocking the microphone opening.

The ANC microphones are usually located on the outer side of the headphones. Gently clean the microphone area using a soft, dry cloth or adhesive pad.

Note: Avoid using liquid cleaners or sprays.

Check the environments

Test in different noise environments: 

ANC is most effective at reducing low‑frequency noise (below approximately 1.2 kHz), such as airplane cabin noise, train noise, air conditioners hum, or background sound in office environments. It is less effective for higher‑frequency sounds, such as voices or sudden sharp noises. Testing in different environments can help you better understand how ANC performs.

Reset 

Reset the headphones.

• Ensure the headphones are powered on.

• Press and hold the Power button and Volume "+" buttons simultaneously for 5 seconds. The red power LED will flash slowly 3 times, indicating that the factory reset process has begun.
