The HyperX Cloud II microphone does not have active noise-cancelling technology. However, it does feature a detachable design, which allows users to remove the microphone when not in use, reducing background noise and improving the headphones' overall aesthetics. Additionally, the microphone has a cardioid polar pattern, which helps to minimize background noise and focus on the user's voice. While it may not have active noise-cancelling technology, the HyperX Cloud II microphone does offer effective noise reduction for clearer communication during gaming or calls.
