Headphones "Noise Cancellation" (ANC) Hissing

4.5

When ANC is on, you hear a faint "white noise" or hissing sound in the background.

Symptoms
  • Hissing sound
  • White noise
  • Pressure feeling
Possible Causes
  • Normal ANC floor noise
  • Microphone feedback
  • Software bug

Step-by-Step Fix

1

Adjust ANC Level

If your app allows it, lower the ANC intensity.

2

Check for Wind

ANC mics can struggle with wind, causing a "whooshing" or hissing sound.

3

Update Firmware

Manufacturers often tune the ANC algorithms to reduce hiss.

When to See a Technician

All ANC headphones have some level of "floor noise"; it's the sound of the anti-noise being generated.
