However, even with such a technique, users often face problems of pairing, communication breaks or poor sound quality. In this article, we will analyze not only the basic connection process, but also the nuances of settings that will help avoid typical errors.
You'll learn how to activate the right search mode on your headphones, what Bluetooth settings in MIUI affect connection stability, and what to do if your phone doesn't see the device. We'll focus on solutions for cases where the headphones are connected, but the sound is only in one channel or with a delay.

Preparing for connection: compatibility and charging check
Before you start pairing, make sure your headphones and phone are ready to go. Many problems arise from trivial reasons: a dead battery of headphones or outdated smartphone firmware.
Check the charge level of the headphones first. Most models (e.g. Xiaomi Buds 3 Pro or JBL Tune 125TWS) have indicators that flash red when low charge. If the headphones are discharged, plug them into the charge case for 10-15 minutes. For models with a wired connection (e.g. Sony WI-C200), use a USB-C or Micro-USB cable.
Next, update your firmware on Redmi Note 10 Pro. Go to Settings → About Phone → System Update and install the latest patches. This is important, as older versions of MIUI (below 12.5) had bugs that supported the LC3 protocol (used in Bluetooth 5.2+ headphones).
- 🔋 Headphone charge: at least 30% for stable connection.
- 📱 Version. MIUI: 12.5 or later (check in Settings) → The phone).
- 🎧 Compatibility: Headphones should support Bluetooth 4.0+ (Most models after 2018).
- 🔄 Reset: If the headphones have previously connected to another device, reset (usually hold the power button 10-15 seconds).

Solving Typical Connection Problems
Even after successful pairing, Redmi Note 10 Pro users face a number of challenges, and let's look at the most common ones and how to fix them.
| Problem. | Possible cause | Decision |
|---|---|---|
| Phone can't see headphones | Headphones are not in pairing mode or discharged | Charge the headphones, activate the search mode (see the instructions above) |
| The sound is interrupted or "breaks" | Interference from other devices or outdated codec | Disable other Bluetooth devices, select the AAC or SBC codec in the developer settings |
| The sound is only in one headphone. | Failure of synchronization between headphones | Place both headphones in the case, pull out and reconnect |
| Lag (Sound Delay) When Watching Video | Uses a high latency SBC codec | Enable Low Latency mode in your headphone settings or select the aptX LL codec (if supported) |
| Headphones are constantly switched off | Weak Bluetooth signal or conflict with other connections | Remove all unnecessary devices from the Bluetooth list, reboot your phone |
⚠️ Attention: If after connecting the headphones, the sound in the speaker of the phone is lost, check the audio output settings. MIUI Sometimes the priority of the device is lost. To fix, swipe the notification panel. → tap on the headphone icon → Select "Phone speaker».
Xiaomi/Redmi models (like Redmi Buds 4 Pro) have Dual Device Connection, which allows you to connect headphones to your phone and laptop at the same time. However, on the Redmi Note 10 Pro, it is unstable due to the limitations of the Snapdragon 732G chipset. If you need this feature, turn it off in the headphone settings via the Mi Earphones app.
Sound optimization: codec selection and MIUI settings
Bluetooth audio quality depends not only on the headphones, but also on the audio codec you choose. By default, MIUI uses SBC, a universal, but not the highest quality codec, and if your headphones support AAC, aptX or LDAC, you can manually activate them.
1. Enable the Developer Mode:
Settings → About Phone → MIUI version (click 7 times in a row)2. Select the optimal codec:
- 🎵 AAC: Best balance of quality and stability (supported by AirPods, Sony, JBL).
- 🎵 aptX/aptX HD: High quality, but may cause delays on some firmware.
- 🎵 LDAC: maximum quality (up to 990 kbps), but requires powerful headphones and can "break" sound at a weak signal.
- 🎵 SBC: universal, but with significant quality losses.
To change the codec:
- Open Settings → Additional → Developer settings.
- Find the Bluetooth Codec and select the desired option.
- Reconnect the headphones.
For fine tuning of sound, use the built-in Equator in MIUI:
Settings → Sound and vibration → Equalizer. You can choose presets (Bases, Rock, Jazz) or create your own profile. Note that the equalizer only works with AAC and SBC codecs.
💡
If the sound gets worse after you change the codec, go back to SBC and check if the headphones are in Noise Reduction or Transparency mode, which can conflict with the codec and cause distortion.
How to Reset Bluetooth Settings on Redmi Note 10 Pro
If the headphones are connected with errors (for example, the sound is only in one channel or the connection is constantly interrupted), resetting Bluetooth will help, which will delete all the saved devices and return the settings to the factory.
1. Open Settings → Connections and Sharing → Bluetooth.
2. Click on the three dots in the top right corner and select Clear cache.
3. Return to the main Bluetooth menu and click Reset Settings (or Forget All Devices).
4. Reboot the phone.
After reset, you will have to re-connect all devices, but this often solves problems with the “glutty” connection. If the reset did not help, try updating the headphone firmware (for Xiaomi models, this is done through the Mi Earphones app).
⚠️ Attention: On some firmware MIUI (In this case, a complete reset of the network will help: Settings → Connections and sharing → Network reset. It will delete all stored Wi-Fi networks and passwords!
Useful chips: headphone management through MIUI
The Redmi Note 10 Pro offers a few hidden features for working with wireless headphones that many people don’t know about.
