Why does the noise cancellation effect degrade when using wired earphones during a call on the Xiaomi Pad 7?

Thank you for your support of Xiaomi products. Wired earphones do not support advanced noise cancellation features, as their noise reduction capabilities are hardware-dependent and can not integrate fully with the system’s adaptive noise cancellation algorithms. When switching between different noise cancellation modes while using wired earphones, the system can experience unexpected performance issues, especially when alternating between speaker mode and wired earphones.
To ensure a consistent and effective noise cancellation experience, it is recommended to use standard noise cancellation mode when using wired earphones. If you prefer to use the speaker, first select this mode before switching to other noise cancellation settings as needed. This approach helps maintain stable performance and reduces potential disruptions during calls.
