The Arctis Nova Pro uses the best kind of ANC: a 4-mic hybrid system.
It's an effective combination that builds on two different systems used in previous ANC setups. The worse methods use either a mic outside of the earcup (feedforward) or on the inside (feedback). The former isn't great because it doesn't have a way to filter the good noise from the bad, so it could accidentally amplify certain sounds. The latter isn't equipped to handle high frequencies, and it might accidentally emit unpleasant feedback right into your ear. Not great.
The 4-mic hybrid system places them on the inside and the outside. As the outer mics listen and filter the noise, the inside ones correct it. No need to worry about covering frequencies, any feedback, or even the way you're wearing your headset. You're covered with the best ANC tech out there.
