How to connect Huawei headphones to the Xiaomi Redmi smartphone: full instructions with solutions to problems

Connecting Huawei headphones to Xiaomi Redmi smartphones is a challenge that many users face, especially when switching from one brand to another. Despite the fact that both manufacturers use standard wireless protocols (Bluetooth for wireless models and USB-C/3.5 mm for wired ones), nuances of software and branded chips can create difficulties. In this article, we will examine all possible ways of connecting, from basic pairing to solving common errors such as lack of sound, interruption of communication or microphone problems.

Compatibility is a particular concern: not all Huawei FreeBuds or Huawei Earbuds models work equally well with the Redmi Note 12 or Redmi 10. For example, headphones with Huawei Histen support may require additional settings to correctly play the sound on Xiaomi devices. Also consider alternative methods of connecting through third-party apps and circumventing restrictions MIUI.

If you've tried to plug in your headphones before, but you've encountered a "Device not found" or "Pair failed," you'll find proven solutions in this article, and for wired models, you'll find instructions for adapting the connectors and setting up the sound profile.

1. Huawei headphone compatibility with Xiaomi Redmi: what you need to know

Before you start connecting, it’s important to make sure your Huawei headphones are compatible with Xiaomi Redmi.Most current models support Bluetooth 5.0+ standard, but there are nuances:

• 🔹 Wireless headphones: Huawei FreeBuds 5/4/3, FreeLace, Earbuds 3 are compatible with any Redmi on MIUI 12 and later. However, features like Dual-Device Connection (simultaneously connecting to two devices) can work unstablely.
• 🔹 Wired headphones: Models with a USB-C connector (e.g., Huawei AM115) connect to the Redmi Note 11/12 without adapters. Headphones with 3.5 mm will require an adapter if your Redmi doesn't have an audio jack (as in Redmi 10A).
• 🔹 Branded codecs: Huawei headphones often use codecs AAC and SBC that are supported by Xiaomi, but if your model supports LDAC or aptX, they will have to be manually activated in the developer settings.

Compatibility issues are more common with older headphone models (such as the Huawei Honor AM61) or smartphones on older versions of MIUI (below 11), which may require firmware updates or third-party applications such as Bluetooth Auto Connect.

⚠️ Warning: Huawei headphones with support for Huawei Share (quick connection to Huawei devices) will not automatically detect on Xiaomi Redmi. They will have to be manually connected via the Bluetooth menu.

2. Connecting Huawei wireless headphones to Xiaomi Redmi over Bluetooth

3. Solving Bluetooth Connection Issues

Even with the right pairing, there can be errors, and let's look at the most common ones and how to fix them.

If none of these methods worked, try resetting your network settings to Xiaomi Redmi:

1. Go to Settings → System and device → Resetting.
2. Select "Reset Wi-Fi, Mobile Network and Bluetooth settings".
3. Confirm the action and restart the smartphone.

⚠️ Warning: Some Redmi models (e.g. Redmi 9A) may not support the aptX codec. In this case, sound will be transmitted via AAC, which is slightly degraded quality, but not critical for most users.

4. Connecting Huawei wired headphones to Xiaomi Redmi

Huawei wired headphones are easier to connect, but there are some nuances, especially if we are talking about models with USB-C or an outdated 3.5 mm connector.

For USB-C headphones (such as the Huawei AM115):

1. Connect the headphones to the USB-C port on Redmi.
2. If no sound, check the settings: Go to Settings → Sound → Output. Select "USB-audio" (if any).

If the headphones are not detectable, try using the OTG- adapter (sometimes it helps with unstable contact).

For headphones with a 3.5 mm connector:

• 🔌 If your Redmi has an audio jack (like the Redmi Note 10 Pro), just plug in the headphones.
• 🔌 If there is no connector (as in Redmi 10), use the USB-C → 3.5mm adapter. Note: not all adapters support the microphone!
• 🔊 If the sound is quiet or distorted, check the Equator settings in the Mi Music app or Google Play Music.

Important: Huawei Active Noise Canceling (ANC) headphones may not work properly through the USB-C adapter. In this case, noise reduction will be turned off, and sound can be transmitted with interference.

💡

If the wired headphones are connected but the microphone is not working, try cleaning the jack with a wooden toothpick, often the problem is poor contact.

5. Adjusting the sound for optimal reproduction

After successfully connecting Huawei headphones to Xiaomi Redmi, it is recommended to adjust the audio profile for better quality. MIUI has several useful options:

1.Selection of Bluetooth codec
