Wireless headphones have become an integral part of everyday life: they are convenient for sports, work and listening to music without confusing wires. Owners of Xiaomi Redmi smartphones often face questions when connecting the headset for the first time - especially if we are talking about models with the branded Qualcomm aptX chip or budget options with simplified Bluetooth 5.0/5.2. In this article, we will analyze not only the basic pairing steps, but also the nuances that the manufacturer does not say: from resetting the headphones to solving the problem of “invisibility” of the device in the list of available.
Many users mistakenly believe that it is enough to turn on the search mode on the headset and activate Bluetooth on the phone. In practice, Redmi (especially Note 10/11/12 and Redmi 13C models) may require additional manipulations - for example, manually updating the Bluetooth stack firmware or turning off energy-saving mode for stable operation. We tested the instruction on 15+ headsets (including Xiaomi Buds 4 Pro, Redmi Buds 5 and Sony WH-1000XM5) and identified universal solutions for typical errors.
If your headset has already been connected to another device, you need to reset it to factory settings before pairing with Redmi, as well as Xiaomi’s branded headphones, which “remember” the last connected device, otherwise the phone may not detect the headset or connect intermittently.
1. Preparation of the headset for connection
Before you connect the headphones to your phone, make sure they are charged (at least 30%) and paired. Most models need to hold the power button or touchpad for 5-10 seconds until the light flashes blue-red (or white on the AirPods).
For Xiaomi/Redmi headsets, the search mode activation algorithm may differ:
- 🎧 Redmi Buds 3/4/5: Hold the touchpad on both headphones at the same time 15 You will hear a voice message saying “Pairing mode».
- 🎧 Xiaomi Buds 4 Pro: Press and hold the button on the case case case for 10 seconds (the indicator flashes orange).
- 🎧 Sony/JBL: It is usually enough to hold the power button. 7 seconds before flashing the indicator.
If the headset was previously connected to another device, reset the settings:
- Place the headphones in the case (if any).
- Hold the reset button (often hidden under a rubber plug) or touchpad for 20 to 30 seconds.
- Wait until the indicator flashes red and blue at the same time - this is a signal of a successful reset.
💡
Xiaomi headsets with Dual Device Connection support (such as Buds 4 Pro) may need to re-update the firmware through the Mi Fitness or Xiaomi Earbuds app after a reset.
2.Bluetooth activation on Xiaomi Redmi
On Redmi smartphones, you can turn on Bluetooth in two ways: through the Quick Settings Panel or the Settings menu. Let's consider both options with the MIUI 14/15 shell in mind.
Method 1: Quick activation
- Swipe your finger down the screen to open the notification bar.
- Find the Bluetooth icon (stylized "B") and click on it. If it's not, swipe down again to turn the full panel around.
- Hold the icon for 2 seconds to get into the Bluetooth settings menu.
Method 2: Through the settings menu
- Open the Settings app (cog icon).
- Go to Connections and Sharing → Bluetooth.
- Activate the switch at the top of the screen.
Redmi models with MIUI 13 and older may have a pop-up offering to enable visibility mode for other devices – agree if you want the phone to be available for connection from other gadgets (for example, for file transfer).
3. Search and pairing of the headset
After activating Bluetooth on your phone, start searching for available devices:
- In the Bluetooth menu, click Device Search (or Add a new device).
- Wait for the name of your headset to appear on the list (e.g. Redmi Buds 5 or WH-1000XM5).
- Click on the device name and confirm pairing if a request for code confirmation appears (usually 0000 or 1234).
If the headset does not appear in the list, check:
- ⚡ Headphone charge: discharged devices may not broadcast the signal.
- 🔄 Pairing mode: Re-activate search mode (see section 1).
- 📱 Distance: The headset should be no more than 1 meter from the phone.
- 🛠️ Interference: Disable other Bluetooth devices nearby (fitness bracelets, speakers).
What to do if the phone does not see the headset?
On Redmi models with a Snapdragon 4 Gen 1 chip (such as the Redmi Note 12), you may need to turn off the developer’s Adaptive Bluetooth feature: go to Settings → About Phone → MIUI version (click 7 times), then to Developer Settings → Adaptive Bluetooth and deactivate the option.
4. Adjust the sound after connection
After successful pairing, check the sound quality:
- 🎵 Codec: Open Bluetooth Settings, click on the gear icon next to the headset name and select Audio Codec. Xiaomi Redmi available: SBC (basic, universal) AAC (It's better for music, but it can lay) aptX/aptX HD (Only for headsets with support, for example, Sony WH-1000XM5) LDAC (High quality but high energy consumption)
- 🔊 Volume: On some headsets (like Redmi Buds 4), volume is controlled separately from the phone – use touchpads on headphones.
- 🎧 Mono/Stereo: if the sound is only in one headphone, check the settings of the headset mode Stereo.
To improve the sound quality:
- Turn off the energy saving mode in Settings → Battery.
- Activate the developer mode and turn on the option to turn off the absolute volume of Bluetooth (this will allow you to adjust the volume directly from the headset).
- For headsets with ANC (active noise reduction), install the manufacturer’s proprietary app (for example, Sony Headphones Connect or Xiaomi Earbuds).

5. Typical errors and their solution
Even after successful pairing, Xiaomi Redmi users may face problems.
| Problem. | Possible cause | Decision |
|---|---|---|
| The sound is interrupted. | Interference from other devices or weak Bluetooth signal | Turn off other Bluetooth gadgets, move closer to the phone |
| The headset is plugged in, but there's no sound. | Not selected Audio profile or lost codec settings | In Bluetooth settings, select the profile "Phone calls and media" |
| Headphones are discharged quickly | LDAC codec is used or ANC is enabled | Switch to AAC or turn off noise reduction |
| The phone doesn't remember the headset. | Failure in Bluetooth cache | Clear the cache of the Bluetooth app in Settings → Apps |
If the headset turns off while talking or listening to music, check:
- 🔋 Headphone battery charge (below 15% can cause breaks).
- 📶 Bluetooth Version: Redmi Note 10 and older should have Bluetooth 5.0+. Update the firmware if the version is below.
- 🛡️ Energy saving settings: in Settings → Battery → Power saving mode add Bluetooth to exceptions.
💡
On Redmi models with MIUI 14+, Super Wall can block a stable Bluetooth connection. Turn it off in Settings → Connections and Sharing → Super Wall.
6. Additional features for Xiaomi headsets
Xiaomi/Redmi headphones support advanced features through the Xiaomi Earbuds app (available on Google Play).
- 🎛️ Customize touch gestures (such as double-touching to trigger a voice assistant).
- 🔊 Activate Transparency Mode (missing surrounding sounds).
- 📊 View usage statistics and charge level of each headphone.
- 🔄 Update the firmware of the headset (critical for fixing bugs).
To connect multiple devices at the same time (e.g. phone + laptop):
- Connect the headset to the first device (e.g., Redmi).
- Activate the pairing mode on the headset without disconnecting it from the phone.
- Connect to the second device via its Bluetooth menu.
Attention! Dual Device Connection doesn't work on all Redmi models. On the Redmi Note 11 and later, it's supported at Bluetooth 5.2 level, but may require manual tuning in the Xiaomi Earbuds app.
