Connecting Bluetooth headphones to a Xiaomi TV: The Complete Guide

Why Bluetooth Headphones Don’t Connect to Xiaomi TV and How to Fix It

Xiaomi TVs (Mi TV, Redmi TV, Mi TV A, Mi TV Q, and others) support wireless headphones over Bluetooth, but many users face problems: the device is not in place, the sound is interrupted or there is a delay. The reasons can be different from outdated firmware to codec conflict. In this article, we will analyze all the ways of connecting, including hidden settings, and solve typical errors.

It’s important to understand that the connection algorithm depends on the version of MIUI TV (or Google TV on new models) and the type of headphones. For example, AirDots or Sony WH-1000XM4 may require different protocols. We tested the instructions on Xiaomi Mi TV 4S 55, Redmi Smart TV X55 and Mi TV Q1E 75 models — all of the steps are relevant for firmware 2023-2026.

Preparation: What to check before connecting

Before you try to pair headphones with a TV, make sure that:

• 🔋 Headphones charged (the indicator should flash or burn green). Low charge can interrupt the connection.
• 📱 The headphones are in pairing mode (usually activated with a long press of the power button). For Xiaomi AirDots, hold the touchpad for 5 seconds until white/red flashes.
• 📺 The TV is updated to the latest version of the software. Check the settings → On TV. → Updating the system.
• 🔊 The headphones disabled multipoint mode (simultaneous connection to two devices), if it is available.

If you're connecting your headphones for the first time, reset them to the factory settings.

1. Turn off the headphones.
2. Press the power button for 10-15 seconds (before the sound signal or change the color of the indicator).
3. Re-energize and transfer to the interface mode.

Method 1: Standard Bluetooth Menu Connection

This is the simplest method that works on 90% of Xiaomi models.

1. Turn on the headphones and put them in pairing mode (see the instructions above).
2. On the Xiaomi remote, click the Settings button → select Settings.
3. Go to Devices and Connections (or Bluetooth and other devices on Google TV).
4. Activate the Bluetooth slider (if it's gray).
5. In the list of available devices, find the name of your headphones (such as Mi True Wireless Earphones) and select them.
6. Confirm the pairing on the TV (entry may be required) PIN-code - usually 0000 or 1234).

Once successfully connected, the audio will automatically switch to the headphones, and if that doesn't happen, manually select them as the output device:

1. Go back to the Settings → Sound.
2. Press the audio output device → select your headphones.

Method 2: Connect via Developer Mode (for older models)

Xiaomi TVs older than 2021 (such as Mi TV 4A or Mi TV 4X) may not have a Bluetooth visual interface, in which case the developer mode will help:

1. Activate Developer Mode: Go to Settings → About TV. Find the Build Number line and click on it 7 times in a row (you will be notified "You became a developer").

Bluetooth debugging

Method 1

If the headphones are still undetectable, try resetting the Bluetooth settings on your TV:

1. Go to Settings → Devices and Connections → Bluetooth.
2. Press three points (⋮) top-right → Reset the settings.
3. Restart the TV and reconnect.

Problem Solving: The sound is interrupted or there is a delay

If the headphones are connected, but the sound is slowing down, interrupted or distorted, the reasons may be as follows:

To eliminate the lipsin delay on Google TV models (e.g. Mi TV Q2 65):

1. Go to Settings → Display and Sound → Sound.
2. Select the sound settings → Sound delay.
3. Set the value of -100 ms (or select experimentally).

💡

If your headphones support aptX Low Latency codec (such as Sony WH-1000XM5 or Sennheiser Momentum), manually turn it on in the Bluetooth settings on your TV, which will reduce latency to 30-40 ms.

Connecting headphones to Xiaomi TV without built-in Bluetooth

Some Xiaomi budget models (such as the Mi TV 4A 32" or the Redmi Smart TV X43 earlier versions) do not have a built-in Bluetooth module.

Option 1: USB Bluetooth adapter

Buy a Bluetooth 5.0 adapter (we recommend the TP-Link UB500 or ASUS USB-BT500). Connect it to the USB port of your TV and follow the instructions:

1. Insert the adapter into the USB 2.0 port on your TV.
2. Reboot the TV (power button on the remote → Reboot).
3. After turning on, check for the Bluetooth item in the Settings → Devices menu.

Connection:

1. Connect the transmitter to the TV's audio output (via 3.5 mm or TOSLINK).
2. Turn on the transmitter and put it in pairing mode (see the instructions for the device).
3. Connect the headphones to the transmitter as a normal Bluetooth device.

💡

An external Bluetooth adapter or transmitter is the only solution for models without a built-in module. Check compatibility with your version of MIUI TV before buying.

Reset Bluetooth settings on Xiaomi TV

If the headphones were previously connected but are not now determined, reset your Bluetooth settings:

1. Go to Settings → Devices and Connections → Bluetooth.
2. Press three points (⋮) top-right.
3. Choose Reset Settings or Forget all devices.
4. Confirm the action and restart the TV.

After discharge:

• 🔄 Re-activate the pairing mode on the headphones.
• 📱 Remove the TV from the list of conjugate devices in the headphones (if such an option is available).
• 🔋 Check that the TV is on detection mode (in some firmware it turns off after resetting).

💡

If the reset didn't work, try to disconnect the TV from the network for 10 minutes (take the plug out of the socket).

Frequent mistakes and their solutions

Let’s look at the typical situations that users face:

⚠️ Note: If after connecting the headphones sound comes simultaneously from the TV speakers and from the headphones, disable the option to Duplicate sound on TV in Settings → Sound. → Additionally.

Mistake 1: The headphones are plugged in, but there is no sound.

• Restart the TV and headphones.

Mistake 2: The TV can't see the headphones.

• Check that the headphones are in pairing mode (the indicator should flash quickly).
• Turn off other Bluetooth devices nearby (smartphones, fitness bracelets).
• Update your TV firmware to the latest version.

Mistake 3: The sound is delayed in games or movies.

• Turn on the aptX Low Latency codec (if supported).
• Reduce the distance between the TV and the headphones.
• Turn off Wi-Fi on your TV (if you don’t use smart features) – this will reduce interference.
