CVC (Clear Voice Capture) and ENC (Environmental Noise Cancellation) are both call noise reduction technologies, but they target different problems and application scenarios. Currently, the latest motorcycle helmet Bluetooth headsets mainly use CVC technology.
CVC is different from ENC in filtering noise. Instead, it detects the environmental noise when speaking and the echo generated, and removes the echo and environmental noise as much as possible to provide the other party with a quiet call environment, including the other party hearing a clean and echo-free voice.

ENC mainly suppresses reverse environmental noise, that is, during our call, there are some environmental sounds that are not human voices. Through data detection and filtering of the same noise, the noise is almost gone, and the human voice is retained. Some ENC call noise reduction headsets can also detect the direction of the speaking voice through the dual microphone array effect, strengthen the human voice and remove environmental noise.

The main goal of CVC technology is to reduce the echo during the call. It can effectively eliminate the echo, thereby providing a clearer call experience. The beneficiaries are mainly the other party of the call.
ENC is a more comprehensive environmental noise reduction technology that can accurately calculate the direction of the caller’s sound source, which can not only reduce the echo during the call, but also suppress the surrounding environmental noise.
In terms of relationship, ENC includes CVC, and CVC can be considered a technical solution of ENC. This means that devices using ENC technology usually also have the function of CVC.
Although both CVC and ENC can improve call quality, due to their different design goals, in actual applications, which technology is more effective may vary depending on the situation.
For example, if you are talking in a noisy environment, then ENC may be more suitable for you; and if your calls are often interfered by echoes, then CVC may be more useful.
Both CVC and ENC are based on the purpose of call noise reduction, but the interference signals they target are different. Now that you have a clear understanding of the noise reduction technology and specific algorithms of the headphones, you can better choose the motorcycle helmet headphones that suit you.
