Why Xiaomi Earphones 2 is not working: a full analysis of the causes and solutions

Xiaomi Earphones 2 wireless headphones have gained popularity due to the balance of price, sound quality and convenience. But even the most reliable technology can fail: one of the headphones suddenly stops working, does not connect to the phone or makes distorted sounds. If you encounter this problem, do not rush to throw the headset away - in 80% of cases it can be restored yourself.

In this article, we’ll look at all the possible reasons why one Earphones 2 headphone might be silent or not working properly, from the usual battery drain to hardware breakdowns. You’ll learn how to diagnose a problem, what settings to check first, and when to really go to the service center. And for those who are willing to act on their own, we’ve prepared step-by-step instructions with photos and videos (links to official Xiaomi sources are given at the end of the article).

Spoiler: Half the time, it's not the earbud that's responsible, it's the wrong settings on your smartphone or firmware. Let's start with the simplest one.

1. Checking basic settings: what to do before repair

Before you take your headphones apart or carry them to the shop, make sure that the problem isn’t software settings, and here are four key steps to take first:

• 🔋 Charge the case and headphones. Put the case on charge for 30 minutes, even if the indicator shows charge. Sometimes the headphone contacts oxidize and the charging is unstable. After charging, remove both earphones and check if the indicator is on the idle one.
• 📱 Reset pairing: Remove Earphones 2 from the list of connected devices in your smartphone’s Bluetooth settings (Settings) → Bluetooth → Xiaomi Earphones 2 → Forget the device. Then put the headphones back in the case, close the lid and wait 10 seconds, they will automatically go into pairing mode.
• 🔄 Reboot your smartphone. Sometimes Bluetooth glitches are associated with temporary OS crashes. Restart your phone and try to reconnect.
• 🎧 Mono mode checks, some firmware MIUI Or third-party players can activate Mono mode, where the sound is only going to one earphone. Go to the audio settings and turn off this option.

If the headphone is still not working after this manipulation, move on to the next section. And if you're not sure if you did the pairing reset correctly, here's a video manual from Xiaomi:

Important! If the indicator on the broken earphone does not burn at all (even after charging), this may indicate a break in the contacts inside the case or a failure of the battery, in which case it will require disassembly.

2.Diagnostics of hardware problems: when the "iron" is to blame

If software methods have not worked, the problem is likely to be in the hardware. Xiaomi Earphones 2 wireless headphones have typical "weaknesses" that manifest after 1-2 years of use:

The most common fault is the wear and tear of the contacts in the case or on the headphones themselves, and over time, the spring contacts lose their elasticity, become oxidized or dusty, which causes one of the headphones to fail to charge and, as a result, to fail to turn on.

To check it out:

1. Take a magnifying glass and look at the contacts on the headphone and in the case, they should be clean, without green coating (oxidation) and black spots (burning).
2. Carefully clean the contacts with a cotton swab soaked in alcohol or liquid to clean the contacts (for example, Kontakt 60).
3. Try to slightly bend the spring contacts in the case with a needle - sometimes they sag and do not provide a tight fit.

💡

If there is no alcohol at hand, you can use a regular eraser for pencils - it removes oxides from metal contacts well.

If the earphone is running after cleaning, but the problem returns after a few days, then the contacts are worn out and need to be replaced. In service centers, this service costs from 500 to 1500 rubles, depending on the region.

3. Resetting headphone settings to factory

Xiaomi Earphones 2 features a hardware reset that returns all settings to factory settings, which helps in cases where the headphones are connected but are not working stable (for example, one earphone periodically turns off or the sound is distorted).

Resetting instructions:

1. Place both headphones in the case and close the lid.
2. Press and hold the button on the case for 20 seconds until the indicator starts flashing red and white alternately.
3. Open the case cover – the headphones should automatically go into pairing mode (the indicator flashes white).
4. Connect to them via Bluetooth on your smartphone.

If one earphone still doesn’t work after reset, try connecting it separately:

• Remove the non-working earphone from the case.
• Press and hold the touchpad on the headphone for 10 seconds until the indicator starts flashing white.
• Connect to it via Bluetooth as a separate device (in the list it can appear as LE-Earphones). 2-R or LE-Earphones. 2-L).

Make sure the case is charged more than 30 times%|Check that both headphones are in the case correctly (contact down)|Use the original charging cable|Do not interrupt the reset process until the indicator blinks.-->

Attention! After resetting, all user settings (such as control gestures) will be deleted and reset in the Mi Earphones app.

4. Battery problems: how to check and replace

The batteries in wireless headphones are designed for 300-500 charging cycles. After that, their capacity decreases by 30-50%, and the earphone may not turn on even after a long charge. Xiaomi Earphones 2 uses lithium polymer batteries with a capacity of lithium polymer. ~43mAh in each headphone.

Signs of a "dying" battery:

• 🔋 The headphone discharges quickly (lasts less than 1 hour).
• 🔌 Does not charge until the end (the indicator goes out a few minutes after connecting to the case).
• 🔥 Heated during charging or working.
• 🚫 It does not work despite the charge of the case.

Check the status of the battery can be using a multimeter:

1. Disassemble the headphone (instruction below).
2. Connect the multimeter probes to the battery contacts (plus and minus).
3. If the voltage is below 3.2V, the battery needs to be replaced.

To replace the battery in Earphones 2 will need:

• New battery (article: BAT-43mAh-3.7V, You can find it on AliExpress or in service centers).
• Plastic mediator or guitar mediator for disassembly.
• A soldering iron with a thin sting and solder.
• Clay. B-7000 shell-build.

⚠️ Attention! When disassembling headphones Xiaomi easily damage the plume speaker or Bluetooth antenna. If you have never soldered microelectronics, better contact the service. the average cost of replacing the battery in the workshop is 800-1200 rubles.

5.Disorders with the speaker: why there is no sound, and the earphone connects

If the earphone connects to the phone, the light goes on, but there's no sound -- the problem is probably the dynamics or the circuitry.

• 🔊 In Earphones 2, the plume is very thin and can break if you disassemble or fall sloppy.
• 🎛️ The contacts on the board oxidize. Over time, the contacts that the speaker is soldering to become oxidized, and the signal does not pass.
• 🔇 Membrane damage speaker. If the earphone falls or is exposed to moisture, the membrane may deform.
• 📡 There's a malfunction in the amp. There's an amplifier chip on the headphone board that could fail.

Diagnosing the problem with the speaker can be as follows:

1. Connect your headphone to your phone and run a sound test (for example, through the Mi Earphones app or any online frequency generator).
2. If there is no sound at all, try to slightly press the headphone body from the speaker side - sometimes this temporarily restores contact.
3. Disassemble the earphone and check the integrity of the speaker plume. If the plume is torn, it can be replaced (article: FPC-Earphones2).

If the speaker is physically damaged, it can be replaced. The cost of a new speaker for the Earphones 2 is about 300-500 rubles. The main thing is to choose an original part or a quality analogue (for example, from GoerTek, which supplies speakers for Xiaomi).

6. Bluetooth module problems: the headphone connects and disconnects

If one Xiaomi Earphones 2 headphone periodically turns off or the sound is interrupted, the problem can be hidden in the Bluetooth module. This is one of the most difficult malfunctions, since it can be associated with both hardware (antenna, chip) and software (firmware, phone settings).

Common causes of unstable Bluetooth:

• 📶 Interference from other devices: If 2.4GHz Wi-Fi routers, microwaves or other Bluetooth devices are running nearby, communication may break.
• 📱 Old versions of firmware. Some versions. MIUI (especially up to 12.5) were bugs with Bluetooth 5.0 support.
• 🔧 Codec incompatibility: Earphones 2 headphones support codec AAC, But some phones are trying to use them. SBC, which leads to stuttering.
• 🔌 Bad antenna contact. In the headphone, the Bluetooth antenna is soldered to the board, and when you fall, contact can be disrupted.

What can be done:

1. Update your smartphone firmware to the latest version (in Settings → About Phone → System Update).
2. In Bluetooth settings (Settings) → Bluetooth → The gear next to Earphones 2 → Additionally), select the codec AAC manually.
3. Try connecting your headphones to another device (like a tablet or laptop), and if the problem persists, it's a malfunction in your headphone.
4. If the headphone turns off when you're moving (like walking), the problem may be the antenna cliff, in which case only repairs to the service will help.

⚠️ If you notice that the earphone has started to shut down after a fall or impact, do not try to repair the antenna yourself - this requires professional soldering equipment. SMD-The average cost of repairing a Bluetooth module in the service is 1500-2500 rubles.

7.Moisture and physical damage: what to do after falling or getting water

Xiaomi Earphones 2 doesn’t have official water protection (IP-If the earphone stops working after contact with water or impact, act quickly:

When moisture is ingested:

1. Remove the earphone from the case immediately and do not turn it on.
2. Wet with a napkin the visible moisture on the body.
3. Place the headphone in a silica gel container (boxes made from shoes) for 24 to 48 hours.
4. Do not use a dryer or other heat sources – this can damage the board.

After the fall:

• Check the case for cracks. If there are any, take the earphone apart and make sure the board is free of chipped elements.
• Check if the speaker has shifted – sometimes after the impact it moves away from the body, and the sound becomes quieter or disappears.
• If the headphone is not turned on, check the battery and contacts on the board (see section 4).

If the headphone starts to work unstable after falling or getting moisture (for example, spontaneously turns off or distorts the sound), this may indicate corrosion of contacts or microcracks on the board. In such cases, home repair rarely helps - professional diagnosis is required.

💡

If the headphone has been in water, do not connect it to charging until completely dry! This can cause a short circuit and permanently disable the board.

8.When to contact the service: repair cost and warranty

If you’ve tried all the techniques in this article, but one Xiaomi Earphones 2 headphone never worked, it’s time to contact the service center.

Before you carry the headphones for repair, check:

• 📅 Warranty period: Official warranty on Earphones 2 - 12 months from the date of purchase.If the headphones are warranty, repairs will be free (provided that the breakdown is not your fault).
• 🛠️ Official service. Xiaomi has a map of service centers on its website - choose only authorized workshops.
• 💰 If the repair costs more than 50% of the price of new headphones (about 3000-4000 rubles), it makes sense to consider buying a new model, for example, Xiaomi Buds 4.

Tip: If you decide to buy new headphones, keep the old ones – many services accept them in the payment for repairs of other devices or for spare parts.
