There are a couple of reasons why this will happen:
1. First, in LHDC (Low Latency High Definition Codec) mode, the bitrate is adaptively adjusted based on the level of interference in the surrounding environment. When there is increased interference, such as in crowded areas with many wireless signals, the bitrate can automatically be reduced, which can result in a noticeable drop in sound quality or even static noise. If this occurs, it is recommended to turn off LHDC or switch to a different audio codec;
2. Secondly, when the Redmi Buds 6 Pro are in game mode, they enter low latency mode to reduce audio delay, which can cause a decrease in sound quality. This trade-off between latency and audio fidelity is common in gaming modes designed for real-time performance.
