White noise is a common problem with all speakers and headphones; it is generated when electronic devices operate. Most TWS headphones also have white noise when the system turns on the noise reduction mode. It is a normal phenomenon, not the quality problem of the headset itself, so there is no need to worry.
We added an amplifier chip in the OWS to achieve excellent sound performance. The function of the amplifier chip is to amplify the weak signal from the sound source to achieve a better listening effect. Since OWS is designed for long-time wear, the setting of the OWS power amplifier is enabled by default when no music is played. At this time, due to the characteristics of the amplifier chip, a certain background white noise will be generated.
