Why do voice calls, video calls, and games sometimes experience delays when using the Redmi Buds 6 Play?

The reasons that there are delays when using the earbuds are as follows:
1. The audio is first transmitted from the mobile phone to the main earbud, and then the main earbud transmits the audio to the sub earbud. There will be a certain delay in the audio transmission process, however, it will not affect the music and calls;
2. When the network environment is poor, there will be delays in signal transmission and packet loss;
3. Some games (such as PUBG) have high requirements for latency and mobile processing. There will be slight delays.
