Modern Xiaomi Mi TVs offer excellent image quality, but the built-in acoustics don’t always meet the demands of users, especially when watching movies late at night. Using a wireless headset allows you to immerse yourself in the world of cinema without disturbing the household with extraneous noise. The process of synchronizing devices has become much easier with the advent of the Android TV operating system and the PatchWall proprietary shell.
In this article, we'll look at all the interfaces, look at the possible problems with latency, and offer solutions for different TV models. You'll learn how to properly activate the detection mode on the headset and find it in the menu of the TV. This is a basic but critical feature for comfortable use of multimedia equipment.
Preparation of equipment and activation of the coupling mode
Before you start looking for devices on the TV menu, you need to put your headphones in a special connection standby mode. Most models, such as AirDots, JBL or Sony, require a power button or a special pairing button for 5-7 seconds. The indicator should start flashing quickly, usually in blue or red-blue, which signals readiness to work.
Make sure that the Xiaomi TV is on and you are on the home screen.The distance between the devices should not exceed 1-2 meters during the primary connection, as the signal can be unstable if there are obstacles. Also check the battery level on the headphones, as the discharged gadget may not appear in the list of available devices.
⚠️ Warning: If the headphone light flashes slowly or is on a straight light, the pairing mode is not activated. Repeat the button clamping procedure until the blinking becomes frequent.
Some users find that the headphones automatically connect to a smartphone that is nearby. To avoid conflicts, temporarily turn off Bluetooth on your phone or tablet, which ensures that the headset will look for the TV, and not another familiar device.
Step-by-step connection instruction via Android TV settings
Xiaomi TVs may have different interfaces depending on the firmware version, but the algorithm remains the same. You need to get into the system settings menu, where all external peripherals are controlled. Navigation is done using a remote control.
Follow this algorithm of actions for successful synchronization:
- 📺 Press the “Settings” button (cogs) on the remote or select it in the upper right corner of the main screen.
- 🔊 Go to the Settings section → Sound or Settings → Remote and accessories.
- 🔍 Select "Add Accessory" or "Add Device».
- 🎧 Wait for your headset name to appear in the list and select it to connect.
Once you select the device, you may see a request for confirmation of pairing. Use the navigation buttons on the remote to agree to the terms. Successful connection is usually accompanied by a characteristic audible beep in the headphones and a text notification on the TV screen.
☑️ Checklist of connection
In rare cases, the system may request PIN-The standard combinations for most devices are 0000 or 1234. If the headset requires a unique code, consult the instructions of the audio device manufacturer.
Customization of sound in the PatchWall interface
Xiaomi TVs often run PatchWall, which has its own navigation specifics. In this interface, the audio settings can be hidden in the user profile or in the quick menu. To access them, click and hold the menu button on the remote.
In the window that opens, select the gear icon to go to the full system settings, and here it's important to make sure that the output is switched to the external device, and sometimes the TV continues to output sound through the speakers, even if the headset is connected.
The Developer's Secret Menu
Check if Auto Switch is activated, and if it is enabled, the TV will automatically muffle when you connect the headset, a handy feature that prevents sound from coming from two sources at the same time.
Compatibility table of profiles and codecs
Sound quality and latency are directly dependent on the codecs supported. Xiaomi TVs support a wide range of protocols, but not all headphones can work at their maximum quality. Below is a table of basic characteristics.
| Codec | Sound quality | Delay (Latency) | Compatibility |
|---|---|---|---|
| SBC | Basic | High (200-300 ms) | All devices. |
| AAC | Good. | Medium (100-150 ms) | Apple, Android |
| aptX | High. | Low (40-80 ms) | Qualcomm chips |
| aptX Low Latency | Excellent. | Minimum (<40 ms) | Special. Headsets. |
If your headset supports aptX Low Latency, but the TV doesn’t activate this mode, the sound may be out of sync with the image, so it’s worth checking the settings of the specific app you’re watching the content through, as some players have their own audio engines.
💡
For games and dynamic movies, try to use headphones with support for aptX Low Latency to avoid the effect of “echoing” when shots or door slams.
Note that when you connect multiple devices at the same time (such as a gamepad and headphones), the channel bandwidth may decrease, which will lead to automatic switching to the SBC codec.
Solving problems with sound desynchronization
One of the most common problems with wireless headsets is the lag, where actors' lips move and voices are heard later, and this is due to the time it takes to encode and transmit audio through the air.
To minimize this effect, try the following: First, make sure there are no working microwave ovens or powerful Wi-Fi routers nearby that can cause interference in the 2.4 GHz band. Second, check for updates for the Xiaomi TV.
⚠️ Note: Do not use old-style Bluetooth transmitters (versions 3.0 and below), they introduce a critical latency that cannot be compensated by software.
In some cases, cleaning the cache of the app you are viewing helps. Go to Settings → Apps, find the video service you want (like YouTube or Kinopoisk) and select Clear Cache. This will not delete your data, but can correct decoding errors.
Disconnection and management of connected devices
The connected headset is controlled via the same menu where the pairing was made, and you can turn the device off at any time without turning it off physically, or remove it from the TV's memory if you plan to sell the gadget.
To turn off the sound, you just need to turn off the headphones themselves, the TV will automatically switch to the built-in speakers. If this does not happen, check the settings in the section Sound → Output. There should be a choice of "TV Dynamics" or "Automatic".
If you want to connect the headset to another device, such as a smartphone, remove it from the list of paired devices on the TV, which will prevent automatic reconnection when the phone is in range.
Use of an external Bluetooth adapter
Owners of old Xiaomi Mi models TV, Those that do not have a built-in Bluetooth module can use an external Bluetooth module. USB-Adapter. However, not every whistle is going to work. A TV needs to have drivers for a specific adapter chipset.
It is recommended to use the original Xiaomi adapters or certified models that explicitly state support for Android TV. Insert the adapter in the USB 2.0 port, after which a new option “Bluetooth” should appear in the settings menu.
Consider that using an external adapter can increase the load on the TV processor, which in rare cases leads to slowing down the interface, in which case it is better to free up RAM by closing unused applications.
💡
The built-in Bluetooth module is always more stable and energy efficient than the external ones. USB-Adapters, so when choosing a TV, pay attention to the presence of this feature in the specification.
Once the adapter is installed, the search and connection procedure is completely the same as the standard algorithm for embedded modules, and the main thing is to make sure that the adapter is inserted into a port that is not occupied by other energy-intensive devices, such as external hard drives.
