GT1/GT2 The reasons can be both software (firmware failure, battery discharge) and hardware (damage to the speaker or contacts). 80% In case of malfunction, it is possible to eliminate it yourself - without contacting the service center.

In this article, we'll look at all the possible reasons why one Xiaomi earbud is silent, and give you step-by-step diagnostic and repair instructions, learn how to reset, flash your device, clean your contacts, and even replace your battery if it's the problem, and for complex cases, tell you how to find original parts and avoid running into a fake.

Before you put your headphones in the shop, check out the simple solutions: maybe it's a dead battery or a dirty contact in the case. Let's start with the basic diagnostics!

1. Diagnostics problem: why is one headphone Xiaomi silent

The first thing you need to do is to determine the nature of the malfunction, and that depends on which repair method you choose, and here are the key signs and their possible causes:

• 🔋 The headphone does not turn on at all (no indication, does not respond to buttons) → battery discharged, control board or contacts in the case are damaged.
• 🔊 The earphone is on, but there's no sound. → speaker problem, grid contamination or firmware failure.
• 🎧 The sound is interrupted, there is interference. → weak Bluetooth signal, interference from other devices or damaged cable (in semi-wireless models).
• 🔄 The earphone is working and it's shutting down. → unstable connection to the case, wear of contacts or failure of synchronization.

Pay special attention to touch-controlled models (such as Xiaomi Mi True Wireless 2 or Redmi Buds 3 Pro). Often the problem lies in the sticking of the sensor, which causes the earphone to "think" that it was removed from the ear, and mutes the sound. Check this out simply: lightly tap on the body of the broken earphone — if the sound appears, it is the sensor that is to blame.

Important! If the earphone is on, flashing, but there is no sound, try connecting it to another device (smartphone, tablet, laptop). If the problem persists, a malfunction in the earphone itself. If the sound appears, the Bluetooth module of your gadget is to blame.

2. Basic actions: what to do first

Before you take your headphones apart or bring them to the service, follow 5 simple steps. In 60% of cases, this is enough to return the sound:

1. Reset the headphones. Place both earphones in the case, close the lid, and wait 30 seconds. Then pull them out and check the work.
2. Check the charge. Make sure the case is charged (the indicator should burn), and the headphones are correctly positioned on the contacts. Sometimes it is enough to move the earpiece in the socket to start charging.
3. Reset Bluetooth settings on your smartphone: Settings → Bluetooth → Click on the gear icon next to the headphones → Forget the device then perform re-pairing.
4. Update the firmware. Some models (Mi True Wireless 2, Redmi Buds 4) are available with updates via the Mi Home app or Xiaomi Wear.
5. Check the earphone on another device (another smartphone, PC) to help eliminate the problem from the source of the sound.

A critical mistake many users make is trying to fix headphones without checking the charge of the case. In Xiaomi models, the case not only stores, but also synchronizes the headphones. If it is discharged, one of the headphones can fall off the pair.

⚠️ Attention! Do not use faster chargers with higher power to charge the case 5W (1A/5V). This can damage the power controller and lead to unstable headphones.

3. Resetting Xiaomi headphones to factory

If the basic methods didn't work, the next step is to completely reset the settings, which will remove all pairings and return the headphones to factory condition.

Once reset, Xiaomi headphones may not sync with each other.

2. Take out only the main headphone (usually the right one) and connect it to the phone.
