tws bluetooth headset factory believe that active noise reduction belongs to hardware noise reduction. The principle is to use the circuit to pick up the surrounding environmental sound, and then convert it into an inverted sound signal and add it to the speaker end. The sound presented to the human ear is environmental noise + inverted The environmental noise is reduced intuitively, and the beneficiary is oneself.

Another main noise reduction technology is software noise reduction, also called CVC noise reduction. It is the software noise reduction technology that comes with the CSR chip. It only works when making a call. With this technology, the surrounding environmental noise can be attenuated. , The other party will be able to hear a clearer voice.

At present, TWS headsets that can achieve active noise reduction on the market are generally effective. Friends who need noise reduction can buy special sports Bluetooth earphones and special noise reduction earphones.
