Connecting wireless headphones to Xiaomi Redmi Note 5: full instruction with troubleshooting tips

Xiaomi Redmi Note 5 is still a popular choice among users who appreciate reliability and functionality at an affordable price, but owners of this smartphone often face questions when trying to connect to it wireless headphones — especially if we are talking about models with Bluetooth 5.0 support or proprietary chips like Qualcomm aptX. In this article, we will examine not only the basic pairing process, but also the nuances of working with different versions of MIUI, as well as typical errors that interfere with stable connection.

It’s important to consider that Redmi Note 5 is equipped with a Bluetooth 4.2 module, which imposes certain restrictions on data transfer speed and compatibility with new devices. For example, headphones with support for LC3 (as in Bluetooth 5.2) will work, but without the benefits of the new codec. We tested the connection with popular models — Xiaomi AirDots, Sony WH-1000XM4, JBL Tune 510BT — and identified key points that will help to avoid problems.

1. Preparation of the smartphone and headphones for connection

Before you start pairing, make sure both devices are ready to connect. The Redmi Note 5 should have Bluetooth enabled and the headphones in search mode (usually activated by holding the power button for a long time). If you connect the headphones for the first time, they will automatically go into pairing mode after being removed from the case (for example, for the first time). TWS-models or inclusions.

Pay particular attention to the following points:

• 🔋 Headphone battery charge: if the charge level is below 20%, the connection may be interrupted. Charge the device to at least 50%.
• 📱 Version. MIUI: on old assemblies (below) MIUI 10) may not have profiles for modern headphones. Update the software through Settings → The phone. → Updating the system.
• 🔄 Reset previous connections: If the headphones were already paired with another device, delete them from memory via Bluetooth Settings → Devices → Forget it.

Redmi Note 5 with firmware below MIUI 11 may not support AAC codec, which worsens the sound quality when listening to music through Spotify or Apple Music, in which case we recommend using headphones with support for SBC or update the software.

2. Step-by-step connection instruction

The pairing process takes less than a minute, if you follow a clear algorithm, and we break it down into stages based on the features of MIUI:

1. Activate Bluetooth on your smartphone: swipe down the screen to open the notification bar, and click on the Bluetooth icon (or go to Settings → Connections → Bluetooth).
2. Put the headphones in search mode: For TWS-headphones (e.g. Xiaomi AirDots): take them out of the case and hold the touchpad on both headphones for 5 seconds until the indicator starts flashing red and blue. WH-CH710N): Hold the power button for 7-10 seconds until you hear a voice message saying “Bluetooth pairing».

After successful connection in the status bar will appear icon headphones, and in the Bluetooth settings the device will be marked as “Connected”.

3. Customize Bluetooth sound and profiles

By default, the Redmi Note 5 uses an A2DP profile to transmit audio, but for voice calls it can automatically switch to HFP (Hands-Free Profile), which reduces the sound quality.

1. Go to Settings → Sound → Bluetooth sound quality.
2. Select a priority codec: 🎵 SBC — universal, but with mediocre quality. 🎧 AAC — Best for music (not available on all firmware). 🔊 aptX – Optimal for Qualcomm chips (requires headphone support).

Automatic switching to HFP

To check your current codec, use the Bluetooth Codec Info app (available on Google Play). If your smartphone is persistently using HFP while making calls, that's fine -- that's how the protocol works.

💡

If the sound in the headphones is interrupted, try turning off the “Absolute Volume” function in Settings → System → For developers (if the partition is unlocked).

Typical problems and their solutions

Even after successful pairing, Redmi Note 5 users may face a number of problems, and we've collected the most common ways to fix them:

If Xiaomi headphones (like AirDots Pro) refuse to connect, try resetting them to factory settings: place both headphones in a case, then hold the button on the case for 15 seconds until the indicator starts flashing red.

5. Optimization of wireless headphones

To maximize your experience, use these tips:

• 🔄 Update the firmware of headphones: many manufacturers (for example, Sony or Sony) JBL) They release updates to improve compatibility. Check them through branded applications (Sony Headphones Connect, JBL Portable).
• 📴 Turn off battery savings for Bluetooth: go to Settings → Battery → Saving charge → Apps and add Bluetooth to exceptions.
• 🎛️ Set up the equalizer: use the built-in equalizer in MIUI (Settings → Sound. → Equalizer) or install Wavelet from Google Play to fine-tune the sound to specific headphones.

If you use active noise cancellation (ANC) headphones, note that the Redmi Note 5 may not support this feature due to the limitations of Bluetooth 4.2. In this case, noise cancellation will work, but with less efficiency than on new smartphones.

💡

For stable operation of wireless headphones with Redmi Note 5, it is recommended to keep them at a distance of no more than 5 meters from the smartphone and avoid physical obstacles (walls, furniture) between devices.

6. Alternative ways of connecting

If Bluetooth refuses to work consistently, consider alternatives:

• 🎧 Bluetooth 5.0 adapter: connects to a 3.5 mm connector and provides support for modern codecs — 1Mii B06 Pro or Avantek APTX.
• 🔌 USB-C audio adapter: if the headphones support wired connection via USB-Type C (e.g. Sony) WH-1000XM4), adapter USB-C → 3.5 mm.
• 📶 Low latency apps: To view video, install SoundAssistant (from Samsung, works on Xiaomi) to sync sound with picture.

Keep in mind that adapters can consume extra battery power and the sound quality through 3.5mm will be higher than Bluetooth, but you will lose mobility.

7. Compatible with popular headphone models

We tested the connection of several popular models to the Redmi Note 5 and made a compatibility table:

For AirPods owners, it’s important to note that they’re optimized for the Apple ecosystem, so on Android, some features (like automatic switching between devices) won’t work.

8. Security and confidentiality

When connecting wireless devices, don't ignore security issues.

• 🔒 Turn off Bluetooth when not in use: This will reduce the risk of connecting third-party devices and save battery life.
• 👤 Check the list of associated devices: remove unknown gadgets through Settings → Bluetooth → Devices.
• 🛡️ Update: Vulnerabilities in Older Versions MIUI They can allow attackers to connect to your smartphone.

⚠️ Note: If you connect headphones in a public place (such as a cafe or airport), avoid using features like “available on some models.

It’s also worth turning off the “All Device Visibility” option in Bluetooth settings after the connection is complete, which will make your smartphone less visible to scan.

💡

Check the permissions of apps that request access to Bluetooth regularly, and some programs (such as fitness trackers) may use it to collect your location data.
