Is the situation familiar? Don't rush to throw the headset or carry it to the service center. In 80% of cases, you can solve the problem yourself in 10 to 30 minutes.

In this article, we will analyze all possible causes, from simple battery discharge to hardware malfunctions, and give step-by-step instructions with photos and videos (where this is critical). The material is relevant for all Xiaomi models: AirDots (Pro, Youth, SE), Buds 3/4/5 Pro, FlipBuds Pro, Piston and others. If your model is not on the list, do not worry: the diagnostic algorithm is universal.

We warn you right away that some methods, like disassembling the earphone, require precision and may be insecure, but if the headphones are no longer warranty or you're willing to take risks, follow our recommendations. Let's start with the simplest.

1. Check basic settings: sound, balance, connection

Before disassembling the headphones or resetting them to factory settings, make sure that the problem is not in the software settings of your smartphone or PC.

• 🔊 Check the sound balance. On Android: go to Settings. → Sound. → Balance L/R. On iPhone: Settings → Universal access → Audiovisual content → The stereo balance, the slider should be in the middle.

• 🎵 Test it on another device. Connect your headphones to another smartphone, tablet, or PC. If the right earphone is running, the problem is with the first device, not the headset.
• 🔋 Charge the case and headphones. Put both earphones in the case for 10-15 minutes, even if the indicator is green. Sometimes the contacts of the case oxidize, and the right earphone does not charge properly.

If you don't have a sound after this manipulation, move on to the next step, but first answer the question:

Important! On some Xiaomi models (like the Buds 4 Pro), the sound balance is adjusted directly in the Mi Home or Xiaomi Earbuds app. Go to the headphone settings section and check the Stereo balance setting.

• 🔌 Oxidation or contamination of contacts in the case or on the earpiece.
• 🔊 Dynamic damage (membrane rupture, soldered wire) often occurs after falling or moisture is ingested.
• 📶 Bluetooth antenna malfunction in right earphone.
• 🔋 Battery failure: The earphone doesn't turn on or off after a few seconds.

How do you diagnose?

1. Look at the contacts. Take out your right earphone and flash a flashlight on the metal contacts (usually 3-5 pieces), if they are blackened or covered with white plaque, they should be cleaned.
2. Check the response to the charge. Put the earphone in the case and watch the indicator. If it doesn't light up, there's a problem with the contacts or the battery.
3. Listen to the noise. Turn on your headphones and put your right one in front of your ear. If you hear a crackle, a hiss, or a very quiet sound, you're probably damaged by the speaker.

If you find physical damage, you can try to fix the headphones yourself (about this in the next section) or take to the service. The cost of repairing the speaker in Xiaomi starts from 1,500 rubles, replacing the battery - from 1,000 rubles.

3. For persistent oxides, use an eraser: lightly rub the contacts, then remove the crumbs with a dry cotton swab.
4. Let the earpiece dry for 10-15 minutes (alcohol evaporates quickly, but it is better not to rush).
5. Put the headphone in the case and check if the charging indicator is on fire.
