If the Redmi Buds 4 Pro has a delay during voice, video and gaming, please refer to the following troubleshooting steps:
1. Check if there are any firmware updates available for your earphones. Updating the firmware can sometimes resolve issues related to sound quality and performance;
2. It may be because the battery of the mobile phone or earphones is insufficient, please fully charge it before observing;
3. Ensure that the earphones are properly connected to your device via Bluetooth. Sometimes, intermittent connectivity issues can result in voice delay;
4. Test the earphones with different audio sources (music, videos, calls) to determine if the issue persists across different applications or content;
5. Affected by the use environment, network, and mobile phone codec speed, it may cause varying degrees of delay when the mobile phone audio data is transmitted to the headset. If multiple routers or Bluetooth devices are used at the same time around the earbuds, there will be varying degrees of interference, and there may be stuck, intermittent, and disconnected situations;
6. The unobstructed effective connection distance between the earphones and the mobile phone is 10 meters, and delay or disconnection may occur after exceeding it;
7. Reset the earphones, delete the connection record of the earphones in the device, and restart the device before pairing.
If the above troubleshooting methods can’t resolve the issue, please contact our local official service center or your seller for further assistance. They will help you in this regard.
