Xiaomi right earphone does not work: diagnosis and repair in 10 minutes

You've turned on your favorite playlist, but the sound comes only from the left earbud and the right one is silent like a fish? This problem is familiar to many Xiaomi owners, from budget Redmi Buds to flagship Mi True Wireless Earphones. The reasons can be different, from a banal clogging of the speaker to serious hardware malfunctions. But in 80% of cases, the earbud manages to "resuscitate" yourself - without going to the service center.

In this article, we’ll look at all the possible reasons why Xiaomi’s right-hand earphone stopped working, from software failures to physical damage. You’ll get step-by-step instructions with photos, videos, and checklists to help get your stereo back in 10 to 30 minutes. And if the problem turns out to be more serious, you’ll learn how to save on repairs and avoid getting scammed.

1. Checking basic settings: why the headphone can "silence"

Before you take your headphones apart or carry them to the shop, make sure that the problem is not with your smartphone or the device itself. Often, Xiaomi’s right-hand earphone stops working because of:

• 🔊 Incorrect sound balance in the phone settings (sound shifted to the left).
• 📱 Bluetooth connection failure (earphone connected but not sound reproduction).
• 🔋 The battery in the right headphone (relevant to the TWS-model).
• 🎧 Activated mono mode (for example, for telephone conversations).

Start with a simple one:

1. Check the sound balance: On Android: Settings → Sound. → Sound balance (if available) on iPhone: Settings → Universal access → Audiovisual → The stereo balance. The slider should be in the middle, and if you move it to the right, the left earpiece will be quieter, and vice versa.
2. Reconnect the headphones: Forget the device in Bluetooth settings. Turn off and turn on the headphones again (for example, to use the device). TWS — Put it in the case for 10 seconds.
3. Check the charge: For Redmi AirDots, Mi Buds and more TWS-Models: Take both earbuds out of the case and look at the indicators. If the right one doesn't blink, it's dead. Put the headphones in the case for 30 minutes, then try again.

💡

If you have Xiaomi Mi True Wireless Earphones 2 or newer, try resetting: press and hold the touchpad on both headphones for 15 seconds until the red light flashes.

If after these manipulations the right earphone is still not working, move on to the next step.

2. Headphone cleansing: eliminate blockages and oxidation of contacts

One of the most common causes of silence in the right earphone is clogging of the speaker or oxidation of contacts. Dust, earwax, sweat and even small debris can block sound or cause short circuits, especially for models with an open speaker grille (Redmi Buds 3 Pro, Mi Earphones Basic).

You'll need:

• 🧻 Cotton swabs (better with a plastic rod).
• 💧 Alcohol (70% or higher) or electronic cleaning liquid.
• 🔦 Lantern (to view the speaker).
• 🧲 Magnet (for models with metal lattice).

For wireless headphones (TWS):

1. Take the earpiece out of the case and examine the speaker under the flashlight. If you see debris, carefully remove it with a dry cotton swab.
2. Wet the stick in alcohol and wipe the speaker grille without pressing (do not allow liquid to get inside!).
3. If the lattice is metal, hold the magnet, it will attract small metal particles.
4. Blow the headphone with a light stream of air (can be mouth or canister to clean the keyboard).

For wired headphones:

1. Check the 3.5mm connector or USB-C oxidation (green coating).
2. Wipe your contacts with alcohol.
3. Check the cable for inflections - often a cliff occurs at the base of the plug.

Note: If the sound appears after cleaning but becomes hoarse or quiet, this may indicate damage to the speaker membrane, in which case a replacement speaker will be required (see Section 6).

3. Diagnostics of software failures: reset and flashing

Xiaomi's wireless headphones are built on firmware, and sometimes it fails.

• 🔇 No sound in one headphone.
• 🔄 Unintentional disabling of the right earphone.
• 📵 Loss of synchronization between left and right headphones.

Decisions:

Resetting headphone settings

For most Xiaomi models, the reset is done as follows:

1. Put both earphones in the case.
2. Press and hold the button on the case (or the touchpad on the headphones) for 10-15 seconds until the indicator starts flashing red and white.
3. Get the headphones out of the case - they should automatically reconnect.

For Redmi AirDots 3 and later:

1. Get the headphones out of the case.


2.Push and hold the touch panels on both headphones for 20 seconds.




3. Wait for the double beep.

Firmware update

Outdated firmware can cause conflicts with new versions of Android or iOS.

1. Install the Mi Home app (for Android) or Mi Fit (for iOS).
2. Put the headphones on the phone.
3. Open the app, find your headphone model and check for updates.

If after resetting and updating the right earphone still does not work, the problem is most likely hardware.

Verification of synchronization TWS-headphone

In Xiaomi wireless headphones (as in other ones) TWS-The left and right earbuds are connected via Bluetooth Low Energy, and if the synchronization is broken, one of the earbuds can "fall off" or stop playing sound.

Signs of a problem:

• 🎵 The left and right sides play different songs (asynchronously).
• 🔕 The right earphone is connected as a separate device.
• 🔄 Headphones are constantly reconnecting.

How to restore synchronization:

1. Reset the reset (see Section 3).
2. Put the headphones in the right order: Get both earphones out of the case. Wait until they connect to each other (white light flashes) Only then plug them into the phone.

Check on another device.

If the sync isn't restored, the Bluetooth module in the right earpiece may have been damaged, and only repairs will help.

5. Wireless headphone repair: cable break and contact soldering

If you have Xiaomi wired headphones (such as Mi Earphones Basic or Mi Hybrid Pro), the problem most often lies in:

• 🔌 Cable break (especially at the plug or headphone connector).
• 🔊 Damage to the speaker (after falling or getting moisture).
• 🔧 oxidation of contacts in the connector 3.5 mm or USB-C.

How to find the cliff:

1. Connect your headphones to your phone and turn on the music.
2. Carefully bend the cable from the plug to the earpiece, listening to the changes in sound.
3. If the sound appears / disappears when bending - in this place a cliff.

Temporary repairs (if the break at the plug):

1. Cut the plug and clean the wires (usually there are 3-4 veins: red, green, blue / copper and braid).
2. Turn the corresponding wires of the new plug (L - left channel, R - right, GND — land).
3. Insulate with a shrink tube or tape.

If there's a cliff inside the earphone:

You'll need a soldering iron.

• 🔧 Stolen iron (power 20-30 W).
• 🧵 Solder and flux.
• 🔍 Loupe or magnifying glass.
• 🧲 Tweezers.

Algorithm:

1. Carefully disassemble the headphone body (usually it is glued or snapped).
2. Find the place of the cliff (most often it is soldering speaker to the board).
3. Clear the contacts and sell the wires again.
4. Check the chain with a multimeter.
5. Collect the case using glue or bilateral scotch.

💡

If you've never soldered, you should go to the workshop. The wrong soldering can completely disable the headphones.

6. Replacement of speaker or board: when repair is imminent

If after all the manipulations, the right headphone Xiaomi still does not work, most likely the problem is:

• 🔊 Damaged dynamics (membrane torn, coil burned).
• 📱 Faulty board (burned amplifier, Bluetooth module).
• 🔋 Bloated battery (relevant to the TWS-model).

How to diagnose:

• If the headphone is connected, but there is no sound - the problem is in the speaker or amplifier.
• If the headphone is not turned on, the problem is in the battery or the power charge.
• If the headphone is warmed - a short circuit on the board.

Cost of repair in the service:

Where to buy spare parts:

• 🛒 AliExpress – speakers, boards, batteries (delivery 2-4 weeks).
• 🏬 Local radio parts stores – if needed urgently.
• 🔧 Donor headphones – can be found on Avito or in service centers.

💡

Before buying parts, check the exact headphone model. For example, the speakers from Redmi AirDots 2 will not be suitable for Mi True Wireless 2, even if they look similar.

Self-replacement dynamics:

1. Disassemble the headphone case (carefully so as not to damage the board!).
2. Unfurl the old speaker.
3. Seal new, observing the polarity (+ and –).
4. Check the sound before assembly.
5. Collect the body using glue B-7000 (plastic-free).

💡

If you're not sure about your soldering skills, you'd better trust the repairs to the professionals. A mistake can short circuit and cause the headphones to break completely.

7. When it is easier to buy new ones: the economic feasibility of repairs

Sometimes it costs more to repair Xiaomi headphones than to buy new ones. To make an informed decision, consider:

• 💰 Cost of repair vs price of new headphones.
• ⏳ Renovation time (if you need headphones urgently).
• 🔄 Warranty (repair is usually given 1-3 months, for new - 1 year).

Comparative table:

When repairs are justified:

• 🎧 Headphones are more than 3,000 ₽.
• 🔧 Problem with battery or plug (cheap repairs).
• 💖 You are tied to a model (e.g., comfortable fitting).

When is the best time to buy new ones:

• 💸 Repair costs more than 50% of the price of new headphones.
• ⏳ Headphones more than 2-3 years (risk of repeated breakdowns).
• 🔊 Problem in dynamics or board (expensive repairs).
