  Bryan JacksonAug 18, 2025
  A poor Bluetooth connection on your Cowin Wireless Headphones may occur if the Bluetooth signal is weak, out of range, or experiencing interference. To resolve this, move away from any obstructions. Additionally, ensure your headphones are adequately charged, as a low battery can impact connection quality. It is also possible that the compatibility between the headphone and the Bluetooth device is not good, so you can replace the device with a higher Bluetooth version. Check if the network signal is OK (whether the player is in buffer).

  Kristina PriceAug 28, 2025
  If the noise cancelling function on your Cowin Wireless Headphones isn't working, first ensure that the noise cancelling function is turned on. Adjust the earpad position to properly fit your ears, or reset the ear if the earmuffs are loose. Keep in mind that the noise cancelling function is most effective in low frequency ranges such as airplanes, trains, offices, near air-conditioning, and is less effective for higher frequencies, such as human voices.

  Noise or beeping sounds from your Cowin Wireless Headphones can be caused by weak Bluetooth signals or external signal interference. To resolve this, move away from wireless routers or microwaves and move your headphone closer to the Bluetooth device. Avoid using the headphones for extended periods; if the sound becomes intermittent, allow them to rest before reusing.
