If there is a sound delay when the Xiaomi Desktop Speaker Pro Set connects to devices via Bluetooth, please refer to the following troubleshooting steps:
1. Interference from other Bluetooth devices, Wi-Fi signals, or physical obstacles during Bluetooth connection can cause unstable audio transmission and sound delay. Please try to avoid these sources of interference and place the Xiaomi Desktop Speaker Pro Set and connected devices in an open, unobstructed location.
2. Some applications and devices have additional latency in audio processing, which can cause audio and video to be out of sync. Please try to choose applications that directly transmit audio and check your device settings to disable unnecessary audio processing.
3. Generally speaking, for applications that watch videos or perform real-time audio processing, the latency should be kept below 100 milliseconds to ensure audio and video synchronization. In most cases, Bluetooth latency is greater than that of AUX IN or USB connections. Please prioritize using the AUX IN interface or USB data cable connection for a more stable audio experience.
4. If it persists, please contact the official after-sales service for further assistance.
