If you notice poor sound quality or weak low-frequency effects with the Redmi Buds 6 Pro, it is recommended to adjust the earbuds to the optimal wearing angle to minimize sound leakage and improve audio performance. Additionally, you can use the Xiaomi Earbuds APP to select audio effects, enable adaptive listening, and customize the sound effects mode in the audio settings for a more immersive experience.
Please note that the sound effects mode is not supported when using a single earbud. Ensuring proper fit and adjusting the sound settings in the APP can greatly enhance the listening experience and low-frequency effects.
