Enabling noise cancellation on HUAWEI FreeBuds series earphones has no effect

The noise cancellation modes are tailored for different scenarios, and each of them is designed for a specific noise spectrum.

• In a quiet environment (such as an office or meeting room), the noise cancellation effects of different modes are almost the same.
• You are advised to switch between different noise cancellation modes in noisy environments such as subways and airplanes.

If the issue persists, take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance.
