Have you had problems with one Redmi Buds 8 Pro earbud desynchronising?

Why Does Desynchronisation Happen?

Bluetooth Interference

Bluetooth interference can disrupt communication between the two earbuds or their connection to the phone, causing the audio to lose synchronisation.

Xiaomi specifically mentions microwave ovens, monitoring equipment, and areas with many wireless routers as examples of environments where interference can affect the connection.

Contact and Charging Issues

If the earbuds are not seated properly in the charging case, or if the contact points are dirty, they may not reconnect or pair correctly when returned to the case. Xiaomi notes that debris between the earbuds and the charging case contacts can prevent normal operation.

Firmware and App Compatibility

Outdated firmware can cause connection or system issues affecting audio synchronisation. Xiaomi recommends updating the earbuds' firmware through the Xiaomi Earbuds app.

How to Fix Earbud Desynchronisation

Step 1 — Put Both Earbuds in the Case for 60 Seconds

This is the simplest official step and worth trying first.

1. Place both earbuds into the charging case.
2. Close the lid.
3. Wait about 60 seconds.
4. Open the case and reconnect the earbuds to your phone.

Xiaomi recommends this short case reset for situations where one earbud produces no sound or the audio is not synchronised.

Step 2 — Check Charge and Contact Points

• Confirm both earbuds are fully charged.
• Use a cotton swab to gently clean the contact pins on the earbuds and the charging case.
• Check for any protective film or debris between the earbuds and the case.

Step 3 — Restart Bluetooth and Reconnect

• Turn Bluetooth off and back on in your phone settings.
• If the problem continues, delete the pairing record and reconnect.

Step 4 — Update the Firmware

Open the Xiaomi Earbuds app on your phone:

• If an update is available, install the latest firmware for the Redmi Buds 8 Pro.

Step 5 — Factory Reset the Earbuds

If the simpler steps do not resolve the problem, try a factory reset.

1. Place both earbuds into the charging case with the lid open.
2. Press and hold the function button on the bottom of the charging case for about 10 seconds.
3. Wait until the white indicator light flashes rapidly.
4. The earbuds will be restored to factory settings and enter pairing mode again.
5. Delete the Bluetooth record on your phone: Settings → Bluetooth → tap the > icon next to "REDMI Buds 8 Pro" → Unpair.
6. Reconnect the earbuds following the usual pairing steps.

Step 6 — Test With Another Device

• Try connecting the earbuds to a different phone.
• If the issue does not occur on another device, the problem may be with your original phone's Bluetooth implementation.

When to Seek Service

If none of the above steps resolve the desynchronisation issue, the problem may be hardware-related. Contact Xiaomi after-sales service for inspection if:

• The earbuds fail to sync after multiple resets.
• One earbud consistently fails to produce sound.
• The issue persists across different phones and firmware versions.

Final Verdict

Audio desynchronisation between the Redmi Buds 8 Pro earbuds is covered by Xiaomi's official troubleshooting guidance. A short case reset, cleaning the contact points, and updating the firmware are Xiaomi's recommended troubleshooting steps. If the problem continues across different devices after these steps, Xiaomi recommends contacting after-sales service.
