Why is the noise cancelling function not working on my Cowin Wireless Headphones?
- C
  charleswebbSep 3, 2025
  If the noise cancelling function isn't working on your Cowin Wireless Headphones: * Make sure that the noise canceling function is turned on. * Ensure the ears are all wrapped and re-equipped. Adjust the earpad position to fit your ears. If the earmuffs are loose, re-set the ear. * Keep in mind that the noise canceling function is most effective in low frequency ranges and less effective for higher frequencies like human voices. It helps eliminate low frequency noise. The noise canceling function is effective in low frequency ranges such as airplanes, trains, offices, near air-conditioning.
