How to connect wired headphones to Xiaomi 13T: all ways + error solving

Why Xiaomi 13T doesn’t support the standard 3.5mm connector – and what to do about it

Xiaomi 13T is the next flagship of the brand, in which the manufacturer has abandoned the classic 3.5 mm audio jack. This decision is due to the desire to reduce the thickness of the case, improve water protection (IP53 standard) and the promotion of wireless technology. However, for many users, wired headphones remain a priority — whether due to sound quality, lack of delays or just habit.

The problem is, without an adapter or a special cable, you can't directly connect your 3.5mm headphones, but there are at least three ways to work -- from official accessories to workarounds -- and in this article, we'll look at each option with step-by-step instructions, compatibility nuances, and common bugs that spoil the sound.

⚠️ Important: if you use headphones with a microphone, keep in mind that not all adapters support voice transmission, for example, cheap adapters often only work on output, and calls will require a separate solution for voice transmission.

Method 1: Connect via official USB-C adapter → 3.5 mm

The most reliable and recommended Xiaomi method is the use of proprietary adapter USB-C to 3.5 mm (MDY-12-EC).It supports Hi-Res Audio, has a built-in DAC (digital-to-analog converter) and is compatible with all smartphone functions, including:

• 🎵 High-resolution music playback (up to 32 bits / 384 kHz)
• 🎤 Microphone operation (for calls and voice recordings)
• 🔊 Automatic recognition of connected headphones
• 🔋 Low power consumption (does not drain the battery)

How to connect:

1. Insert the adapter into the USB-C port of the smartphone.
2. Connect the headphones to the 3.5mm connector on the adapter.
3. Wait for the notification “Audio device connected”.
4. Open any audio app (such as Mi Music or Spotify) and check the sound.

• The sound is interrupted? Maybe the adapter is not sitting tight in the port. Try another cable or adapter.
• Make sure the headphones support the microphone. CTIA/OMTP-Standard (most modern models, yes).

Method 2: Direct USB-C connection (without adapter)

If your headphones are equipped with a USB-C connector (such as models from Sony, Audio-Technica or Xiaomi), they can be connected directly without adapters, which eliminates loss of sound quality and compatibility problems.

Advantages:

• 🔊 Digital audio transmission – without conversion to analog signal.
• 🚀 Low latency (important for games and videos).
• 🔋 Support for fast charging in parallel with listening (if headphones allow you to use it).

How to connect:

Simply insert the headphone plug into the USB-C port of the smartphone. MIUI automatically recognizes the device and prompts you to select a sound mode (for example, "USB audio" or "Hi-Res").

⚠️ Attention: Not all USB-C-Headphones compatible with Xiaomi 13T. For example, some models require support. USB Audio Class 2.0, which may not be in budget accessories!

💡

If the headphones aren’t recognized, try turning on the developer mode and activating the USB debugging option (sometimes this helps with device initialization).

Method 3: Wireless workaround (if no adapter)

If you don't have an adapter, and you only have 3.5mm headphones, you can use a Bluetooth transmitter. USB-C-port of the smartphone and transmits sound through the air to any 3.5 mm headphone with Bluetooth module.

Pros:

• 🎧 It works with all types of headphones (even old ones).
• 🔋 Not blocking the port. USB-C (You can charge your phone at the same time).

• 💰 Requires the purchase of a transmitter (from the ~1 500 ₽).

Recommended models of transmitters:

• 🥇 Creative BT-W5 (Supported by AptX LL low-latency).
• 🥈 Avantek APTX (budgetary version with good sound).
• 🥉 1Mii B06 Pro (Dual transmission to two devices).

Typical problems and their solutions

Even after connecting correctly, Xiaomi 13T users may experience problems.

1.There is only sound in one headphone

Reasons:

• 🔌 Fragile connection of the adapter or headphones.
