Noise cancellation reduces unwanted noise providing a clearer, more lifelike audio performance. You can choose the noise cancelling
mode based on your listening preferences and environment.
Cowin Active Noise Cancelling
Active Noise Cancelling (ANC) mainly focus on cancelling out lower frequency sounds like engines, aviation environment, trains, traffic
noise etc, so our valuable customers can focus on their music, movies, or books without being disturbed by outside noises. Our ANC
headphones incorporate a microchip that measures ambient sound and generate a waveform that is exact negative of the ambient
sound and mix it with any audio signal our customers desires. Making it possible to listen to audio content without raising the volume
excessively. Please do note, ANC does not cancel out noises like snoring, talking, music or high frequency sounds etc.
Notes:
• While charging, the battery indicator red. When the battery is fully charged, the battery indicator off.
• If the power is lower than 10%, you will hear the "Low Battery" tone, prompting every 10 minutes, until the battery is completely
used up and automatically shuts down.
Notes:
• When only use Bluetooth without noise cancelling, a full charge powers the headphones for up to 30 hours.
• When use Bluetooth with noise cancelling, a full charge powers the headphones for up to 20 hours.
Allow up to four hours to fully charge the headphones.
