Modern Xiaomi smartphones have powerful multimedia capabilities, but even the highest-quality built-in speakers can not always convey the full depth and volume of a piece of music in the same way as a home audio system. Connecting a smartphone to a large screen or soundbar is not just a way to play tracks louder, but also the ability to turn a regular video viewing or party into a full-fledged show with surround sound. Users often underestimate the potential of a phone-TV bundle, limiting themselves to watching video, although the functionality allows you to broadcast clean audio stream with minimal delays.
There are many scenarios where you want to bring sound to external speakers, from watching high-quality movies to organizing background music at a house party. Wireless data technology allows you to do this without unnecessary wires, preserving the aesthetics of the interior and usability. In this article, we will discuss in detail all available methods, from built-in MIUI functions to specialized applications that will help you customize the perfect audio system.
It is important to understand that the quality of the final audio transmission depends not only on the model of your Xiaomi, but also on the capabilities of the TV itself and the communication protocol used. Some methods provide lossless transmission, while others can compress the audio stream for stability of the connection.
Use of the built-in Translation (Cast) function
The easiest and fastest way to bring audio (together with or separately) to the big screen is to use the native broadcast function, which is built into the MIUI or HyperOS shell. This method is based on Miracast technology, which allows you to transmit video and audio over Wi-Fi Direct without having to connect to the same router network, although having a shared network often improves stability.
Once activated, the phone will start looking for available devices within range. If your TV supports Miracast technology (often called Screen Mirroring or Wireless Display on the TV menu), it will appear in the list. When connected, the smartphone screen is completely duplicated on the TV, and any sound played on the phone automatically switches to external speakers, a universal solution that works with any application, whether it is streaming services or local players.
⚠️ Note: When using the method of broadcasting, the screen of the smartphone will be active and can heat up, as well as consume battery power faster, since there is an active encoding of the video stream even when listening to music.
But there are limitations to this method: because video streaming is transmitted, the sound quality can be limited by the broadcast codec rather than the audio file. Also, if you decide to lock the phone screen, the broadcast is often interrupted, which is inconvenient for long-term listening to albums. However, for a quick connection to a Smart TV system, this solution remains one of the most popular.
💡
For stable broadcast without jerking sound, try to be in the same room with the router and TV to minimize interference with the Wi-Fi signal.
Chromecast Technology and Google Home App
A more advanced and energy-efficient way is to use Google Chromecast (built-in) technology, which is embedded in many modern TVs and consoles. Unlike screen mirroring, the phone acts only as a remote control, sending a link to the content or playback command to the TV, and decoding and output of sound is taken over by the TV itself, which saves battery power and uses the phone for other tasks.
To implement this method, make sure that both devices are connected to the same Wi-Fi network. If your TV does not have a built-in Chromecast, you can purchase an external dongle adapter.
The advantage of this approach is that it supports high-quality audio codecs and the ability to control playback from any device on the network. You can play music on your phone, then transfer control to the TV and safely leave while the music is playing. The system automatically adjusts the buffering, ensuring smooth sound even in unstable Internet.
Connection via Bluetooth TV adapter
If your TV is equipped with a Bluetooth module but does not support smart streaming features, you can use it as a regular wireless speaker.This method is ideal for transmitting sound from any application, including those that protect content from copying (DRM) and block screen recording or broadcasting through Miracast.
The pairing process is standard: on the TV, you need to go to the audio or connection settings section, select Add Device and activate Visibility Mode. On a Xiaomi smartphone, turn on Bluetooth in the curtain or through Settings → Bluetooth, find your TV model in the list of available devices and click to pair.
- 🎧 High compatibility: Works with almost any modern TV with Bluetooth.
- 🔋 Low power consumption: Bluetooth Low Energy protocol (BLE) saves battery life.
- 📱 Wi-Fi Independence: No router or internet connection required.
- 🔊 Limited quality: Bluetooth bandwidth may not unlock the potential of Lossless formats.
It's worth noting that when you connect via Bluetooth, you can have a slight desynchronization of sound and image if you're watching video, but for pure music listening, it's not critical. Also, the range is limited, usually no more than 10 meters without obstacles.
Broadcasting over DLNA and Local Area Network
For owners of extensive music libraries stored in the memory of the phone or on the phone SD-The technology will be a great solution. DLNA. It allows you to transfer media over a local network to a compatible TV, and unlike a screen broadcast, only the file itself is transmitted here, which guarantees maximum sound quality without the compression inherent in streaming methods.
To implement this scenario, you will need a DLNA-enabled file manager (such as the one built into Xiaomi’s Explorer or third-party solutions like BubbleUPnP) and a TV connected to the same Wi-Fi network. In Explorer, select a music file, click “More” or menu button, and select “Translate” or “Play on.”
☑️ Checking readiness DLNA
Once you select a device on the list, the TV will download and play the track itself. The main advantage of DLNA is the ability to turn off the smartphone screen or fold the application, and playback will not be interrupted. This makes the method ideal for creating a background atmosphere at long-term events.
⚠️ Attention: When in use DLNA Make sure your router does not block the exchange of data between devices on the local network (function) AP Isolation must be disabled).
Comparison of connection methods: Characteristics table
To make it easier for you to decide on the best way to connect, we have prepared a summary table comparing the main characteristics of the methods considered, each of which has its own strengths and weaknesses, which can be decisive depending on your situation and sound quality requirements.
| Method | Sound quality | Battery consumption | Dependence on Wi-Fi | Management convenience |
|---|---|---|---|---|
| Miracast (Translation) | Medium/High | High-pitched | Not necessarily. | Medium (screen active) |
| Chromecast | High. | Low. | I'll be sure. | High. |
| Bluetooth | Medium (compressed) | Low. | Not required | High. |
| DLNA | Maximum (Lossless) | Low. | I'll be sure. | High. |
As you can see from the table, for audiophile listening, DLNA remains the perfect option, while for everyday use and streaming from the cloud, Chromecast is better suited. Bluetooth remains the “golden mean” for fast audio transfer without setting up networks.
💡
The choice of method depends on the priority: DLNA for quality, Chromecast for convenience, Bluetooth for versatility.
Use of AUX and USB-C cable to 3.5 mm
Despite the development of wireless technology, the good old wired method remains the most reliable and high-quality in terms of delays and bitrate.If your Xiaomi is deprived of a 3.5 mm connector, you will need an adapter. USB-C to 3.5 mm (DAC-adapter USB-C 3.5mm Jack This method allows you to connect the phone directly to the TV's linear input (AUX In) or to the external acoustic system.
The main advantage of this connection is that there is no signal compression and complete independence from interference from Wi-Fi or Bluetooth. Sound is transmitted digitally to the adapter, where it is converted to analog, bypassing all wireless codecs, which is especially important for tracks in FLAC or DSD format.
There are downsides, however: tethering your phone to your TV limits mobility. You can't go far to answer a call or take something from the kitchen without interrupting the music. In addition, some budget adapters can make extraneous noises or "background" into the audio signal, so it's recommended to use certified accessories.

Customization of equalizer and sound effects MIUI
Once you’ve successfully connected your phone to your TV, it makes sense to adjust the output sound for the best result. MIUI’s shell offers built-in audio enhancement tools that can compensate for the shortcomings of the TV’s speakers or, conversely, adapt the signal to powerful acoustics.
Go to Settings → Sound and Vibration → Sound Effects. Here you will find a graphic equalizer that allows you to adjust the frequencies manually, or ready-made presets (Pop, Rock, Jazz). For home theater, Volume Sound or Virtual Dolby Atmos mode is often useful if it is supported by your model.
- 🎚️ Graphic equalizer: manual frequency tuning for bass and high frequencies balance.
- 🎬 Virtual volume: creating the effect of spatial sound on the stereo.
- 🔊 Mi Sound: personalization of speaker profile (headphones do not affect TV).
- ⚖️ Balance: adjusting the ratio of left and right channel.
Don't overuse bass amplification, as the TV's speakers may start wheezing and wireless connections may be interrupted by increased bitrate flow, and the best solution is to adjust the average frequencies slightly for better vocal readability.
