Why are there problems with audio cut-off and poor sound quality on the Redmi Buds 6?

If there is an audio cut-off at the start of playback in video, music, or novel APPs, please refer to the following troubleshooting methods:
This audio cut-off occurs in non-noise cancellation mode. Switching to noise cancellation or transparency mode is recommended to resolve it. This issue is currently being fixed by the development team, and a new firmware version will be released to you in November 2024.
If the call quality is poor, it will be improved based on the specific situation. If the default sound effect quality is unsatisfactory, it is recommended to upgrade to the latest firmware version. You can also switch the sound effect setting to Enhance treble mode in the Xiaomi Earbuds APP for a better experience.
For your reference, please refer to the following steps:
Open the Xiaomi Earbuds APP >> [Audio effects] >> select [Enhance treble mode].
