The noise cancelling feature in Bluetooth headsets refers to CVC 6.0 noise cancelling technology that can filter out the noise picked up by the microphones. This process is different from the active noise cancelling (ANC) feature in headphones.
The CVC itself is a function of processor, Qualcomm and other chip makers build it as a core feature, and the latest gen is often better.
Let’s say you talk on phone in a noisy environment, the caller will hear your voice subtracted from the background noise.
If your Bluetooth headsets have ANC – it will instead filter out the background noises.
I haven’t yet found any Bluetooth headsets which have both CVC 6.0 and ANC.
The boundery Bluetooth headsets and Bluetooth earbuds is bluring, when Bluetooth earbuds’ call performance though is not stellar but close to the Bluetooth headsets. In such as the latest Sony WF-1000MX3 offer NC while making calls, which is involved in 2 processes – reduce the background noise so you hear callers better and noise cancelling mic filter out the noise so the caller will hear you more clearly.
Plantronics Voyager 5200, Plantronics Voyager 3200 and Jabra Talk 2 are the best picks for now – according to thewirecutter.
The boom mic headsets are still the best – other design have not been proved better. Alternative design is expected in the near future.
Here’re specs that continuously improve
- Battery life
- Audio performance – more mic will be built for picking up the user’s voice
- Bluetooth 5.0 – stable connection and power efficiency
- Design – fit securely and comfortable
- New CVC tech developed by Bluetooth chip makers such as Qualcomm
- More smart features like AI, Google Voice, Siri will be soon integrated
