Basic noise: When the Bluetooth headset is wireless noise cancelling earbuds working, the constant slight current sound and the rustling of the components work together. This is due to the bluetooth headset chip, note that all bluetooth headsets will inevitably have bottom noise! Some brands of bluetooth earphones have noise at the bottom, and some brands of bluetooth earphones have very little noise at the bottom. This is related to the design of the peripheral circuit board and the optimization of the software. I recommend using especially sensitive ears (totally unacceptable rustling) rather than bluetooth headphones. Or buy a bluetooth headset that has been optimized for noise at the bottom of the software.

Active Noise Cancellation: Active Noise Cancellation is an additional function of the Bluetooth headset. The chip inside the Bluetooth headset transmits the wave frequency opposite to the ambient sound to suppress the environmental noise. In short, turn on the noise reduction function to make the environment quieter and more focused on listening to music. Power consumption also increases when the Active Noise Cancellation feature of the Bluetooth headset is turned on. Suitable for noisy environments.

CVC noise reduction: The development of CVC (clearvoicecapture) noise reduction processing technology is actually a kind of network technology that can noise reduction in calls, which is proprietary to the product design of Qualcomm Solutions. Let the other party hear clear voice data information. That is to say, using a Bluetooth headset with CVC function to talk or send voice, the other party can hear it more clearly. This social function needs to be specially selected for our friends who often go out to make calls or ride a bike with a lot of wind.

Briefly analyze the relationship between bottom noise, active noise reduction and CVC noise reduction:

1. All bluetooth headphones have background noise. Active Noise Cancellation and CVC Noise Cancellation are additional features that cannot reduce the basic noise of the Bluetooth headset itself. Only Bluetooth headsets optimized for background noise can minimize background noise.

2. Active noise reduction is to minimize environmental noise.

3.CVC noise reduction is call noise reduction. By reducing the noise from the speakers, the other person hears the sound most clearly.
