For your reference, the latency factors are as follows:
1. The latency is caused by environmental interference;
2. The distance between the earbuds and the device exceeds the effective range (10 meters).
To avoid latency, here are some methods as follows:
1. Move the earbuds and the device closer, reset the earbuds and try again;
2. Replace the device to verify whether it is a phone issue.
Note:
1. Affected by the use environment, network, and mobile phone encoding and decoding speed, there will be different degrees of latency when the mobile phone audio data is transmitted to the earbuds. The earbuds use true wireless Bluetooth technology. There will be a certain latency in the process of audio transmission from the phone to the earbuds, however, it will not affect the quality of music and calls. Whether it is the sound details during the call or the rich frequency bands in the music, it can be truly presented;
2. Due to the different audio transmission protocols of different phones and APPs, different encoding formats are used. Therefore, the sound latency will occur due to encoding compatibility issues.
