1. Checking the basic settings: why the headphone is “silent” because of the software

Before you disassemble the device or carry it to the service, eliminate software failures. In 30% of cases, the problem lies in the settings of the smartphone, the firmware of the headphones or Bluetooth connection conflict.

Start with the simplest:

• 📱 Check the sound balance. On Android: go to Settings. → Sound. → Left/right speaker balance. On iOS: Settings → Universal access → Audiovisual content → The stereo balance, the slider should be right in the middle.
• 🔄 Reset the headphones. For wireless models, put both earphones in the case, close the lid, wait 10 seconds and pull them out. For wired ones, turn off and plug the plug again.
• 🔗 Reset the pairing. Remove the headphones from the list of Bluetooth devices on the phone (Settings) → Bluetooth → ⚙️ headphone-name → Remove it, then reconnect it.
• 📲 For models with support for updates (for example, Xiaomi FlipBuds Pro), check the relevance of the software through the Mi Home app or Xiaomi Wear.

If you don't recover the sound after this manipulation, move on to the next section, and pay particular attention to the balance of sound, which is the most common cause of "one-way" malfunction that users often forget.

2. Diagnostics of wireless headphones: battery, synchronization, interference

Xiaomi’s wireless headphones (especially budget models like Redmi AirDots) often suffer from power and synchronization problems.

A. Discharge of one of the headphones

• 🔋 Pay attention to the charge indicators in the case, and if one earphone is discharged more than the other, it can automatically turn off to save energy.
• ⚡ Connect the case to charge for 30 minutes, even if the indicator shows a charge.

B. Loss of synchronization between headphones

If the headphones connect to the phone, but only one sound is on, they cut the connection to each other to reconnect.

1. Put both headphones in the case and close the lid.
2. Pull them out and hold the button on the case (or touchpad on the headphones) for 10-15 seconds until the red/white indicator flashes.
3. Wait 1-2 minutes – the headphones should automatically sync (orange or green lights flash).

External interference

Xiaomi headphones run at 2.4 GHz, which can conflict with other devices (routers, microwaves, wireless mice).

• 📶 Step 1-2 meters away from the router or other Bluetooth devices.
• 🔄 Switching your headphones to Game Mode (if any) via the Mi Home app reduces latency and improves stability.

💡

If the headphones start to "glutch" after updating the phone's firmware, try rolling back the Bluetooth stack version. On Android, you can do this through Settings. → System system → Resetting settings → Reset network settings (does not delete data, but resets all associated devices).

Problems with wired headphones: connector, cord, contacts

In-Ear Headphones and Hybrid Pro HD) The causes of one-way sound are usually mechanical. Start the diagnosis at the most vulnerable point, the 3.5 mm connector or the jack. USB-C.

How to check the connector:

1. Take a different set of headphones and plug it into the same device, and if the sound is going well, your headphones are the problem.
2. Connect your headphones to another gadget (like a laptop), and if it doesn't work, it's the cord or speaker.
3. Light a flashlight into the headphone jack, and if you see bent or oxidized contacts, they should be cleaned (see below).

Contact cleanup:

Oxidation or dirt on contacts is a common cause of bad sound.

• 🧴 Cotton swab soaked in alcohol solution (at least 70%).
• 🔍 A magnifying glass or magnifying glass to see small details.
• 🧲 Dry soft fabric for final wipe.

Gently wipe all the metal parts of the connector and plug. Do not use needles or sharp objects - this will damage the coating!

Cord check for cliff:

The most vulnerable spot is the area near the plug and the speakers.

1. Connect the headphones to the device and turn on the music.
2. Carefully bend the cord in different places, starting from the connector. If the sound appears/disappears, there's a cliff.
3. For temporary repairs, you can isolate the problem area with tape (but this is not for long).

Hardware malfunctions: speaker, membrane, chips

If all the previous steps didn't work, the problem is probably hardware, and in this section, we'll look at what might have broken inside the earphone and whether it can be repaired by itself.

A. Damage to the speaker or membrane

Signs:

• 🔊 The sound is there, but it wheezes, distorts, or is very quiet.
• 💥 The headphone stopped working after falling or getting moisture.

In this case, the speaker membrane could break or unstuck. Self-repair is possible, but requires care:

1. Disassemble the headphone body (usually it is glued or snapped).
2. Check the membrane for tears. If it's intact but has moved away, glue it carefully with a special glue for speakers (not superglue!).
3. If the membrane is torn, the speaker must be replaced.

B. Failure of the chip or contacts

In wireless headphones, they often burn out:

• 🔋 Power controller (if the headphone is not charged and not turned on).
• 📡 Bluetooth module (if the headphone is not connected to the phone).
• 🎛️ Amplifier (if there is a sound, but very quiet).

If you're not an electronics expert, you'd better put the headphones in service, and the cost of repairs is usually 30 to 50 percent of the price of new headphones.

B. Moisture intrusion

Even if the headphones are positioned as waterproof (IPX4/IPX5), Prolonged exposure to water or sweat can cause contact corrosion:

• 💧 The headphone stopped working after rain, exercise or shower.
• 🔌 On the contacts visible white or green coating (oxidation).

What to do:

1. Disassemble the headphone and dry all the details with a hairdryer in cold mode or in rice (at least 24 hours).
2. Clean the contacts with alcohol or a special liquid to remove oxides.
3. If after drying the headphone did not work - a replacement fee is required.

💡

Waterproofing (IPX4/IPX5) It protects against splashes, not from being completely immersed in water. If Xiaomi headphones “sink”, they should be immediately turned off, dried and not turned on at least a day.
