Connecting headphones to Xiaomi Redmi smartphones seems like a simple task — until you face unexpected problems. Some users can not find a jack for wired headphones, others spend hours trying to sync Bluetooth headphones with your phone, and still others are faced with the fact that the sound goes only to one earphone. In this article, we will analyze all possible ways of connection (including hidden MIUI functions), explain why Redmi may not see the headphones, and give a checklist for troubleshooting.
It’s important to understand that the way you connect depends on the type of headphones (wireless/wireless), the smartphone model (since the Redmi Note 10, the manufacturer has abandoned the 3.5 mm connector), and even the version of MIUI. For example, the MIUI 14+ firmware has changed the search algorithm for Bluetooth devices, and Redmi 12 has support for LE Audio, the new standard for wireless sound, and we have taken all these nuances into account to make the instruction work for any Redmi model released after 2020.

1. Connecting wired headphones to Xiaomi Redmi
Wired headphones are divided into two types: with a traditional 3.5 mm jack and with a USB-C (or Lightning for iPhone). In Xiaomi Redmi, the situation is complicated by the fact that since the Redmi Note 11 and Redmi 10 2022, the manufacturer completely abandoned the audio jack. If your model is older (for example, Redmi 9A or Note 9 Pro) – there is a connector. You can check this by technical specifications or just by examining the bottom of the smartphone.
Models without 3.5 mm will require a USB-C adapter (official from Xiaomi or third-party). Important: not all adapters support a microphone! For example, cheap Chinese adapters often transmit only sound, but not voice during calls. The official Xiaomi USB-C to 3.5mm adapter (MDY-12-EC) costs about 500 rubles and is guaranteed to work with a microphone.
- 🎧 For models with 3.5 mm connector (Redmi 9, Note) 9S, 8A etc.: just insert the plug into the socket. The sound should automatically switch to the headphones. If this does not happen, check the cleanness of the connector (often dust accumulates) or restart the phone.
- 🔗 For models with USB-C (Redmi Note 12, 11 Pro, 10 2022: Connect the adapter to the port, then insert the headphones. In some cases, you will need to confirm the permission to access the audio in the pop-up window.
- ⚠️ Mike problem? Try another adapter or check the app settings (for example, WhatsApp or Telegram may have the wrong sound source selected).

| Model Redmi | Presence of 3.5 mm | Adapter type | Microphone support |
|---|---|---|---|
| Redmi 9A/9C/9T | ✅ Yes. | Not required | ✅ Yes. |
| Redmi Note 10/10 Pro | ✅ Yes. | Not required | ✅ Yes. |
| Redmi Note 11/11 Pro | ❌ No. | USB-C → 3.5 mm | ⚠️ Depends on the adapter. |
| Redmi 12/12C | ❌ No. | USB-C → 3.5 mm | ✅ Yes (with official adapter) |

⚠️ Attention: If after connecting wired headphones sound comes simultaneously from the speaker and headphones - check the settings in Settings → Sound. → Sound output. Dynamic mode may be on. + Headphones (Dual Audio function in some firmware).
Connect Bluetooth headphones (including TWS)
Wireless headphones connect to Xiaomi Redmi via Bluetooth, but there are a few nuances here: First, MIUI implements Fast Pair (fast bundle) function, which works only with certified devices (for example, Xiaomi Buds or Redmi AirDots). Second, new firmware has support for LE Audio and LC3 codecs, which improves sound quality, but can cause compatibility problems with older headphones.
General connection scheme:
- Open Settings → Bluetooth and turn on the module.
- Transfer the headphones to pairing mode (usually you need to hold the power button for 3-5 seconds until the indicator blinks).
- In the list of available devices, select your headphones and confirm the connection.
For TWS-Headphones (for example, Redmi Buds 4 or Xiaomi Buds) 3T) process is slightly different:
- 🔄 Get both headphones out of the case - they should automatically turn on and enter pairing mode.
- 📱 The phone will be notified "New headphones found" (if supported by Fast Pair).
- 🎵 Once connected, check the sound in both headphones. If only one sounds, reset the headphone settings (usually by holding a button on the case). 10-15 seconds).

If Redmi can't see headphones, try:
- Turn off and turn on Bluetooth on your phone again.
- Reboot the headphones (remove from the case, hold the 10 sec button).
- Clear Bluetooth cache: Settings → Applications → Application management → Three dots (menu) → Show system → Bluetooth → Clear cache.
- Update the firmware of the headphones (if there is such software, for example, for Xiaomi Buds through the Mi Earphones app).

3. Sound settings in MIUI: optimization for headphones
Even if the headphones are connected correctly, the sound can be quiet, distorted or unstable. MIUI has hidden settings that will help improve the quality of playback, for example, the Mi Sound Enhancer feature automatically adjusts the equalizer to the type of headphones, and LDAC (Bluetoothcooking Codec) allows you to transmit sound in high resolution.

For gaming headphones (such as Redmi Gaming Headset), it is useful to enable low latency mode:
- Put the headphones on.
- Open Settings → Special features → Settings for developers (if the partition is hidden, tap 7 times on the MIUI version in About Phone).
- Find the option Absolute Bluetooth Latency and select Low.
💡
If you hear noise or cracking at high volume, try turning off the Mi Sound Enhancer and lowering the volume level in the audio settings by up to 80%. Some Redmi models have distortions at 100% volume.

| Noise/cracking | Interference from Wi-Fi or 4G | Switch to SBC codec or turn off mobile data |
4 Headphones connected but not working: diagnosing problems
If the headphones are connected, but there is no sound or it is distorted, follow this algorithm:
- Check physical connection: For wired headphones, try another cable or adapter. For Bluetooth, make sure the headphones are charged (the indicator should burn green).
- Diagnostics of software settings: Open Settings → Sound → Output and make sure that the headphones are selected. Check whether Do Not Disturb or Quiet mode is on.
Resetting:
- For Bluetooth: Remove the device from the list and reconnect.
- For wired: clear the connector of dust and reboot the phone.
If the problem persists, use this table to clarify the diagnosis:
| Symptoms. | Wired headphones | Bluetooth headphones |
|---|---|---|
| No sound at all. | Check the connector for damage, try another cable | Make sure the headphones are not connected to another device |
| It's sounding, but it's quiet. | Clean the dust connector, check the volume settings | Turn on Absolute Volume in the Developer Settings |
| The sound is interrupted. | Problem with cable or connector | Wi-Fi/4G Interference, Try SBC Codec |
| The sound is only in one headphone. | Check the cable for fractures. | Reset the headphone settings (hold the 10 sec button) |

Some Xiaomi Redmi models have unique nuances when working with headphones, we have collected the most frequent questions about specific devices:
- 📱 Redmi Note 10/10 Pro: These models are 3.5 mm connector, but when connected USB-C Solution: Turn off the audio processing. MIUI sound-tuning.
For gaming smartphones (Redmi K50 Gaming, Black Shark) there are additional audio settings:
- 🎮 Game Sound Mode: Activated in Settings → Special facilities → Settings for games. Improves spatial sound in shooters.
- 🔇 Disabling echo: In microphone settings (Settings) → Sound. → Microphone settings) turn on the option Noise suppression.
6. Alternative ways to connect headphones
If the standard methods do not work, alternative solutions can be used:
- 🔊 USB-C Headphones: Some models (e.g. Xiaomi Type-C Earphones) connect directly to the port without an adapter.They support digital sound and are often better quality than 3.5mm.
For audiophiles, an external DAC (digital-analog converter) is interesting. For example, Xiaomi USB-C Digital Audio Adapter (MDY-13-EC) supports a resolution of up to 32-bit/384kHz and connects to a USB-C port.
