Connecting headphones to a Xiaomi smartphone is only half the battle. To get really high-quality sound, you need to set them up properly in the system. MIUI. Many users do not even suspect that the settings are hidden functions to optimize the sound for a specific model of headphones โ whether it is wired Mi Earphones or wireless Redmi Buds 4 Pro. Without the right configuration, you risk dim bass, distorted high frequencies, or unstable Bluetooth connectivity.
In this article, we will analyze all the hidden options of Settings. โ Sound and vibration, including rarely mentioned options like Adaptive Sound and Equalizer for headphones:
- ๐ Automatically determine the model of connected headphones and apply the optimal profile
- ๐ง Set up an equalizer for genres of music (from classics to hip-hop)
- ๐ Optimize battery consumption when using Bluetooth headphones
- ๐ Fix common problems (stuttering, communication breaks, low volume)
We pay special attention to the hidden regime "LDAC" Hi-Res Audio, which is activated only when manually set up and allows you to transmit sound in a quality close to the studio. 13/14 and POCO F5 Pro, but disabled by default.
1. MIUI Automatically determines the headphone model
Modern Xiaomi smartphones on the basis MIUI 12+ They can recognize connected headphones and use pre-configured profiles, and this function works for wired models (via 3.5 mm or Type-C) and wireless models via Bluetooth:
When the first connection is made, the system analyzes:
- ๐ Impedance of headphones (resistance measured in Omahas)
- ๐ Frequency characteristics (low/medium/high frequency balance)
- ๐ Type of connection (analog, digital or wireless)
- ๐ท Model (if headphones from Xiaomi โ data taken from the database) MIUI)
For example, when connecting Mi In-Ear Headphones Pro HD The system automatically activates the profile with amplified low frequencies, and for Redmi Buds 4 Active, it optimizes the audio delay for games. MIUI your headphones:
- Connect the headphones to the smartphone
- Go to Settings. โ Sound and vibration โ Headphones
- Look at the line Headphone Type โ there should be a model or category (for example, โIntrachannel with a microphoneโ)
โ ๏ธ Attention: If MIUI Incorrectly identified the model (e.g., showed "Unknown headphones"), manually select the nearest profile in the menu Headphone type. Profile mismatch can cause sound distortion at high volume.
๐ก
For headphones with impedance above 32 ohms (e.g. Beyerdynamic) DT 770 Pro) manually select the profile "High-Home Headphones" - this will prevent distortion at high volume.
2. Manual change of headphone profile in MIUI
Automatic definition doesn't work perfectly, especially with third-party headphones, MIUI It allows you to manually select a profile from pre-configured options:
Open the Settings. โ Sound and vibration โ Headphones โ Type of headphones and choose one of the options:
| Profile | Which headphones are suitable for? | Features of sound |
|---|---|---|
| Intrachannel | Mi Earphones Basic, Redmi Buds 3 Lite TWS | High frequency amplification, clear middle |
| Invoices | Mi Headphones, Sony WH-CH520 | Low/medium frequency balance, wide sound |
| High-domed | Headphones with impedance 64+ Ohm. HD 560S) | Suppression of distortion at high volume |
| For games. | Any headphones when used with games | Reduced delay, increased steps/shots |
| Castomy | For experienced users | Manual equalizer setting |
If your model is not listed, choose the closest option to the type, for example, AirPods Pro will suit the profile "Intrachannel", and for the most common type of model, you can choose the most similar option. JBL Tune 510BT โ "Invoices".
After selecting a profile, check the sound on a track with a wide dynamic range (e.g., "Bohemian Rhapsody" by Queen).
- ๐ Sexual clarity (not to be โsinkedโ in the instruments)
- ๐ต Bass (should be deep, but not "bullying")
- ๐ถ High frequency (do not cut the ear)
Test a bass track (e.g. electronic music)
Listen to the vocals (songs with a clear voice)
Check the high frequencies (violin, plates)
Compare the volume with another profile

- ๐ค Pop - Emphasized vocals and high frequencies
- ๐ง Basses โ Enhanced Low Frequency (for hip-hop and electronic music)
- ๐ผ Custom - manual setting of 10 stripes
For manual adjustment:
- Choose Preset Custom
- Move the sliders to adjust the frequencies: 60 Hz - subbass (depth) 230 Hz - lower middle (warmth of sound) 910 Hz - upper middle (vocals) 3.6 kHz - presence (clearness of instruments) 14 kHz - air (high overtones)
โ ๏ธ Attention: Excessive bass reinforcement (60โ230 Hz) on low-impedance headphones (<20 Oms can cause distortions. Optimal level for most models: +3...+6 dB.

4. Optimization of Bluetooth headphones: codec and bitrate
When using wireless headphones, the sound quality depends not only on the headphones themselves, but also on the selected Bluetooth codec. MIUI Supports the following codecs (from worst to best):
- ๐ SBC โ Basic codec, low quality (128-328 kbit / s)
- ๐ต AAC โ Best for music (up to 256 kbps) but depends on implementation
- ๐ง aptX โ low latency, good quality (352 kbps)
- ๐ LDAC โ Hi-Res Audio up to 990 kbps (available on flagships)
To select the codec:
- Connect your headphones to Bluetooth
- Open Settings โ Connected devices
- Click on the name of your headphones โ Sound settings
- Select Sound Quality and select a priority codec
For activation LDAC (available 12/13/14, POCO F4/F5):
- Enable the Developer Mode (Settings) โ The phone. โ Version. MIUI โ press 7 times)
- Back to Settings โ Additionally. โ For developers
- Find the Bluetooth Codec and select LDAC
- Install Beatrate. LDAC 990 kbit/s (Quality) or 660 kbit/s (Balance)
| Codec | Bitreit | Delay. | Suitable for |
|---|---|---|---|
| SBC | 128โ328 kbit/s | ~100-200 ms | Conversations, podcasts |
| AAC | up to 256 kbps | ~80-150 ms | Music (Apple Music, YouTube) |
