How to connect a wired headset to a Xiaomi phone: instructions for all models

Wired headphones are still a popular choice among Xiaomi users due to stable sound, no delays and unlimited work time. However, with the transition to cableless technology and the removal of the classic 3.5 mm connector, many are having difficulties with connection. In this article, we will discuss all possible ways to connect a wired headset to Redmi smartphones, POCO and Mi – from old models with audio jack to new flagships with USB-C or without any wired interfaces at all.

The feature of Xiaomi phones is the variety of connectors and firmware, which can affect compatibility. POCO The F-series requires additional settings to properly operate the microphone in the headset, and smartphones without a 3.5 mm port (for example, Xiaomi 13 Pro) need adapters. No sound in one headphone, a broken microphone or automatic switching to the speaker.

It is important to keep in mind that even with the right connection, the sound quality can depend on the version. MIUI And the codecs installed. At the end of the article, you'll find FAQ answering frequent questions and compatibility table of popular Xiaomi models with different types of headsets.

1. Check compatibility of the headset and phone Xiaomi

Before you plug in your headphones, make sure they are physically compatible with your smartphone. Xiaomi has three types of wired headset jacks:

• 🔌 3.5 mm (mini-jack) – classic audio jack, present in models until 2020 (Redmi Note 8 Pro, Mi) 9T) and some budget lines (POCO M3).
• 🔗 USB-C — Universal port used in modern flagships (Xiaomi 12, Redmi) K50) and many models without 3.5 mm.
• ⚡ Lightning (adapters only) is rare for Xiaomi, but some users are plugging in Apple headsets via adapters.

Also, pay attention to the type of headset plug:

• 🎧 CTIA/OMTP — The standard for microphone and button slinging. Most of today's headphones use CTIA, However, older models (such as Nokia) may be OMTP, Which will lead to a broken microphone.
• 🔊 Without a microphone – if your headset doesn’t have a built-in Mic, connectivity issues are unlikely, but functionality will be limited.

A critical feature for Xiaomi owners: models with MediaTek processors (for example, Redmi Note 11 on Helio) G88) They may not recognize headsets that are non-standardly slapped, even if the connector fits physically, and in such cases, only replacing headphones or using an external DAC will help.

2. Connect the headset to Xiaomi with a 3.5 mm connector

If your smartphone is equipped with a classic audio jack (for example, Redmi). 9A or POCO X3 NFC), Connection process as simple as possible:

1. Insert the headset plug into the 3.5mm connector before clicking. Make sure it is fully inserted – users often experience a “one-working headphone” problem precisely because of incomplete contact.
2. Wait for the "Headset Connected" notification to appear in the status bar. If the notification doesn't appear, try removing and inserting the plug again.
3. Open any audio app (such as Mi Music or YouTube) and check the sound.

If the sound is not available or is played only through the speaker:

• 🔇 Check the sound mode in the notification curtain – sometimes the phone automatically switches to Dynamic or Bluetooth".
• 🔧 Go to Settings. → Sound. → Sound quality and select Headset as output device.
• 🔄 Reboot your phone – it will reset temporary audio recognition errors.

If the person can't hear you, but the sound in the headphones is, chances are, the problem is the slinging (CTIA vs OMTP). Decisions:

• 🛠️ Use a adapter with a correct tilting (e.g. CTIA-to-OMTP).
• 📱 Update the firmware - in new versions MIUI 14+ Improved support for non-standard headsets.

3. Connecting the headset to Xiaomi via USB-C

Smartphones without 3.5 mm connector (Xiaomi) 11T, Redmi K40, POCO F4) require the use of a headset with USB-C Or an adapter. Here's the step-by-step instruction:

Option 1: Headphones with USB-C plug-in
