Where is the microphone on Xiaomi devices: smartphones, headphones, speakers

You try to find a microphone on your Xiaomi device but don't know where it is located? This problem is familiar to many users - especially when you need to check the microphone's health, clean it or diagnose problems during calls. Depending on the model, the location of the microphones can be radically different, from classic holes on the bottom panel to hidden grilles under the screen or in the headphones.

In this article, we will explore all the possible options for the location of microphones on smartphones, wireless headphones, smart speakers and even Xiaomi fitness bracelets. You will learn how to visually identify the microphone, where to look for it on popular models (from Redmi Note 12 to Xiaomi 14 Ultra), and also get practical tips for checking and eliminating typical problems. If you encounter something that the interlocutor does not hear you, here you will find a solution!

Why it’s important to know where the microphone is on Xiaomi

The microphone is one of the most vulnerable elements in the smartphone, and it's in constant contact with the environment, and it's dust, moisture, mechanical damage, all of which can make it go downhill. Knowing where the microphone is, it can help you to:

• 🔍 Quickly diagnose a malfunction (for example, if the interlocutor complains of poor hearing).
• 🧹 Clean the microphone from dust or dirt without damaging other components.
• 🛠️ Properly disassemble the device for repair or replacement of microphone.
• 🎧 Optimally position your smartphone during calls or voice recording.

In addition, some Xiaomi models have multiple microphones (up to 4!), and each is responsible for its function: the main one for calls, an additional one for noise cancellation, a third for recording video. If you do not know where they are, you can accidentally close the most important microphone with your finger - and the sound quality will deteriorate dramatically.

⚠️ Note: On devices with a subscreen speaker (for example, Xiaomi Mix 4 or Redmi) K60 Pro) The microphone is often located next to the front camera, not to be confused with an infrared sensor or LED!

Where is the microphone on Xiaomi smartphones: general principles

Most Xiaomi smartphones have microphones in standard locations, but there are exceptions.

1. The bottom panel is the most common place, usually a small hole next to the connector. USB-C In some models, the microphone is hidden under a decorative grille.
2. Top panel – here often set the second microphone for noise reduction (for example, on Poco) F5 Or the Redmi Note 11 Pro).
3. Next to the front camera – typical for flagships with thin frames (for example, Xiaomi) 13T).
4. Under the back cover - on older models (for example, Redmi) 4X) The microphone could be placed next to the main camera.

To determine exactly where the microphone is on your model, use this table:

If your model is not in the table, use the universal search method:

Light a flashlight on the bottom/top panel – the microphone will be visible as a small hole with a metal mesh

Call another phone and point your finger at the body – when the sound is quieter, you’ve found the microphone.

See official documentation on the Xiaomi website (Section "Technical Specifications")

Use a magnifier to inspect small details (especially on flagships with hidden microphones)-->

How to check if the microphone works on Xiaomi

If you find a microphone but are not sure it will work, do a simple diagnostic.

• 📞 Test call: Call a friend or another phone and ask them to rate the sound quality. If the voice is interrupted or there is a noise, there is a problem.
• 🎤 Recorder: Record your voice on the built-in voice recorder (Recording sound in the application menu) and listen to the recording.
• 🤖 Service code: Enter ##4636##, select Phone Information and check microphone status.
• 🔧 Third-party apps: Install Microphone Test or Sound Meter from Google Play for detailed check.

If the microphone is not working, the reasons may be:

• 🚫 Pollution: Dust or dirt blocks the sound channel.
• 💧 Water intake (even after the "water-resistant" models of the Redmi Note 11 Pro type) 5G).
• 🔌 Software Failure: Error after Update MIUI.
• 🛠️ Mechanical damage: Fall or impact on the body.

⚠️ Attention: On active noise cancelling devices (e.g. Xiaomi 13 Ultra), turning off additional microphones in settings can degrade sound quality!

Where is the microphone on Xiaomi wireless headphones

Xiaomi headphones (AirDots, Buds, FlipBuds) have different microphones than smartphones, depending on the design of the headphones:

• 🎧 Inlays (TWS): The microphone is usually located on the headphone leg (e.g. Xiaomi AirDots 3 Pro or Buds 4.
• 🎧 Overhead/full size: The microphone is built into the cup case (e.g. Xiaomi FlipBuds Pro) or on a flexible cord.
• 🎧 Gaming headphones: An additional microphone can be corded with volume control (e.g. Xiaomi Hybrid Pro) HD).

To find the microphone on Xiaomi headphones, follow the following steps:

1. Examine the earpiece leg (where it is inserted into the ear) – often the microphone is hidden under a rubber seal.
2. Check the case next to the buttons – usually a small hole with a metal mesh.
3. If headphones with noise cancellation (for example, Xiaomi Buds) 3T Pro, microphones can be on both sides (for better voice capture).

If the sound quality is poor, try:

• 🧼 Carefully clean the microphone with a soft brush or compressed air.
• 🔄 Reconnect your headphones to your phone (sometimes resetting your Bluetooth connection helps).
• 📱 Update the firmware headphones through the Mi Home app or Xiaomi Wear.

Microphones on smart Xiaomi devices: speakers, bracelets, watches

In addition to smartphones and headphones, microphones are installed on other Xiaomi devices:

🔊 Xiaomi Mi Smart Speaker, Redmi SonikBass)

In speakers, microphones are used for voice control (like calling Alice or Google Assistant), usually available at:

• 📍 On the top panel (near the control buttons).
• 📍 Under the decorative grille on the front.

If the speaker stops responding to voice commands, check to see if the microphone is covered by foreign objects (such as dust or a sticker).

⌚ Fitness bracelets and smart watches (Mi Band 8, Xiaomi Watch 2 Pro)

Most Xiaomi bracelets don’t have a microphone — they don’t support calls. However, smartwatches (e.g. Xiaomi Watch) S3) microphone built-in:

• 📞 Bluetooth calls.
• 🎤 Voice Message Input.
• 🔍 Activation of the voice assistant.

On the clock, the microphone is usually on the side or bottom of the case, next to the speaker.

⚠️ Attention: On the Mi Band 7/8 There is no microphone – these devices are not designed for calls. If you need a conversation feature, choose models from the Xiaomi Watch or Redmi Watch line.

What to do if the microphone on Xiaomi does not work: step-by-step instructions

If you find a microphone but it doesn’t work, follow this algorithm.

Check the physical cleanliness of the microphone (whether there is dirt or moisture)

Restart the device (sometimes helps with software failures)

Update. MIUI Up to the latest version (in the settings About the phone) → Updating the system)

Reset network settings (Settings) → SIM-maps and mobile networks → Resetting settings)

Check the microphone in safe mode (excluding the influence of third-party applications)

Contact the service center if the problem is hardware-->

If the microphone is contaminated, clean it with:

• 🧹 Soft brush (for example, for drawing).
• 💨 Canister with compressed air (do not blow with your mouth - moisture can get inside!).
• 🩹 Cotton swab soaked in alcohol (only for external cleaning!).

Never use sharp objects (needles, toothpicks) to clean the microphone – this almost always results in damage to the membrane!

If the microphone stops working after falling or getting moisture:

1. Turn off the device immediately and remove it. SIM-card/battery (if possible).
2. Place your smartphone in a dry place (such as a silica gel bag) for 24 to 48 hours.
3. Do not turn on the device until you make sure it is completely dry.

💡

If the microphone is only bad in a particular app (like WhatsApp or Telegram), try clearing that app's cache in the settings (Settings) → Annexes → [Name of name] → Warehouse → Clear the cache).

Hidden microphones on Xiaomi: little-known facts

Not everyone knows, but some Xiaomi devices have hidden microphones that are not mentioned in the official specifications.

• 📱 On Xiaomi Mix Fold 2/3 an additional microphone is located under the hinge of the folding screen - it is needed to improve the sound when talking in a folded state.
• 🎮 Black Shark 5 Pro has a separate microphone for streaming, which is activated only in game mode.
• 📸 On Xiaomi 13 Ultra, one of the microphones is used exclusively for recording video in Log profile mode.

Also, on some models, microphones can be dynamically switched depending on the scenarios:

• 📞 During the call, all available microphones for noise reduction are activated.
• 🎥 When shooting video, a microphone on the back can be used to better capture sound.
• 🎵 In karaoke mode (in some regional firmware), the microphone is tuned to amplify voice.

If you suspect that the hidden microphone is not working, check it through the engineering menu:
