How to connect QCY headphones to Xiaomi phone: instructions for all models

QCY wireless headphones have long proven to be an affordable and high-quality alternative to branded accessories. However, when you first connect to Xiaomi smartphones (especially models on MIUI 14/15), users often face problems: the device is not located, the sound is interrupted or only one earphone is working. In this article, we will analyze all possible ways of pairing, including hidden MIUI settings, which the manufacturer does not advertise.

The QCY headphones (like the popular QCY T13 or HT05) feature Realtek or Jieli chips, which sometimes conflict with Xiaomi firmware’s energy-saving optimizations. Not only will we show you basic connectivity steps, but we’ll also show you how to get around common bugs (like the 0x3E pairing error code) and customize the sound to the highest quality. If you’ve tried to connect and nothing has come of it, don’t rush your headphones back to the store. 90% of cases, the problem is solved in 5 minutes.

First, decide what your model is. QCY version MIUI It's critical, for example, for the QCY T2 chip-wise AC693N You need a single algorithm to connect to QCY T1C on Realtek 8763B — You can find the firmware version of the smartphone in Settings. → The phone. → Version. MIUI. Then we'll start setting up.

1. Preparing QCY headphones for the first connection

Before pairing with a Xiaomi phone, QCY headphones need to be switched to a pairing mode. This process differs from one model to another – below the instructions for the most popular options.

For most models (QCY T13, HT05, T2), the algorithm is as follows:

1. Get both earphones out of the case (if it's one). TWS-model).
2. Press the touch button (or mechanical key) on both headphones simultaneously for 5-7 seconds until the indicators start flashing red and white (or blue – depending on the model).
3. Place the headphones next to the phone (no further than 10 cm).

Physical button models (QCY T1, QCY T1C) may need to triple tap the power button to activate the pairing mode. If the light flashes on only one earphone, the second one is discharged or out of sync with the first one, in which case:

Reset both headphones to factory settings (clip the buttons 10-15 seconds before resetting)|Put the headphones in the case for 30 seconds, then pull out|Check the charge of the case (the indicator should burn green)|Try to connect the headphones alternately (first right, then left)-->

Important: If the headphones have already been connected to another device (for example, a laptop or tablet), they must be forced to “forget” on the old gadget, otherwise Xiaomi may not see them. On Android, this is done in Settings → Connected devices → QCY Headphones → Forget.

2. Step-by-step connection to the Xiaomi phone

When the headphones are in search mode, move to pairing with a smartphone. The instructions are relevant for all Xiaomi models (from Redmi Note 10 to Xiaomi 14 Ultra) on MIUI 12-15:

Step 1. Open Settings → Bluetooth on your phone and activate the switch. Wait for a device called QCY-T13, QCY-HT05 or the like to appear on the list (depending on the model).

Step 2. Tap the headphones on the list. If you have a request for code confirmation (usually 0000 or 1234), type it. Some QCY models don't require code.

Step 3: Wait for the "Connected" message. If the process is stuck in the "Connected" stage for more than 30 seconds, interrupt the attempt and repeat the steps.

Xiaomi phones with dual Bluetooth (e.g. Xiaomi 13 Pro) may have the option of selecting a sound profile: "High-quality sound (AAC/aptX)" or "Low latency (for games)". For music, choose the first option, for games - the second.

If the headphones are connected, but the sound is only in one of them, check:

• 🔋 The level of charge of both headphones (in the case should be a light indicator).
• 🎧 Settings of sound balance in Settings → Sound. → Streo balance (slider should be in the middle).
• 🔄 Try to turn off and reconnect the headphones.

💡

On some QCY models (e.g. T13), you need to press the left earphone touchpad 4 times quickly to reset the mono connection.

3. Solving typical connection problems

Even after successful pairing, Xiaomi users are faced with bugs. Let’s consider the most common and ways to fix them.

Problem 1: Phone can't see QCY headphones

Causes and solutions:

• 📱 Bluetooth is turned off in power saving: go to Settings → Battery → Energy saving regime → Settings → Bluetooth and make sure the switch is active.
• 🔄 Conflict with other devices: disable all other Bluetooth gadgets (fitness bracelets, speakers) and repeat the search.
• 🛠️ Failure of the firmware headphones: reset QCY before factory settings (press the buttons for 15 seconds before flashing red).

Problem 2: Connection is interrupted with 0x3E error

This error is typical for MIUI 14+ and is related to Bluetooth protocol conflict.

1. Update your phone firmware to the latest version (in Settings → About Phone → System Update).
2. Turn off the “Dual Bluetooth Connection” function in Settings → Connections → Bluetooth → More.
3. Install the Bluetooth Auto Connect app from Google Play – it forcibly reconnects devices.

Problem 3: The sound is interrupted or delayed

Blame: Bluetooth codecs or background processes.

• 🎵 Turn on the settings. → Bluetooth → Sound quality → Priority Stability (reduces latency but reduces quality).
• 🚫 Close all apps that use the microphone (such as WhatsApp or Zoom).
• 🔄 Reconnect the headphones by manually selecting the codec SBC (The most stable, but not the best quality).

4.Sound optimization for QCY headphones on Xiaomi

By default, MIUI uses audio settings that are not optimized for QCY. To unlock the potential of the headphones, follow these steps:

1. Selection of Bluetooth codec:

Go to Settings → Bluetooth → Settings (cog next to QCY) → Sound quality. Options available:

• 🎧 SBC — universal but mediocre quality.
• 🎵 AAC — Best Music Balance (Recommended for Apple Music or Spotify).
• 🎮 aptX/aptX LL — for games and movies (low delay).

Equalizer setting:

In Settings → Sound → Equalizer, select the preset Basic Boost or Pop Music for QCY T13/HT05. For classics, "Clean Sound" will work. If there is no equalizer, install the Wavelet app from Google Play.

3. Disconnecting the post-processing of sound:

MIUI It uses the "Bass Enhancement" effect and "3D-"Sound" that spoils the sound QCY. Turn them off in Settings. → Sound. → Sound effects.

💡

For LDAC-enabled QCY models (e.g. QCY T18), manually select this codec in Bluetooth settings – it gives better quality, but can cause communication breakdowns over 5 meters.

5. Hidden MIUI settings for stable connection

Xiaomi hides some Bluetooth options that could improve QCY performance.

Activation of the developer mode:

Go to Settings. → About the phone and 7 times tap on the "Version" MIUI". Return to the main settings – the item “For developers” will appear".

2. Optimization of Bluetooth:

In Settings → For developers, find:

• “Bluetooth bandwidth” – select “High”.
• Bluetooth Codec – Set AAC or aptX (if supported).
• "Bluetooth debugging" - turn on (helps with communication breaks).

3. disabling automatic switching of devices:

MIUI 14+ has a "Auto-Connect to Last Device" feature that may interfere. Turn it off in Settings → Bluetooth → Additional → Auto-Connection.

💡

If your headphones stopped connecting after the MIUI update, reset your network settings: Settings → System → Settings Reset → Reset your Wi-Fi, mobile network and Bluetooth settings. This will remove all the saved devices, but solve the compatibility problem.

6. Alternative ways of connecting

If standard pairing doesn’t work, try these methods:

1. Connection via QCY application:

Download the official QCY app from Google Play. It allows you to:

• 🔄 Update firmware QCY (relevant T13 new).

Manual addition of the device:

If QCY do not appear in the list, click "Add device" in Settings → Bluetooth and select "Other." Type in. MAC-Headphone address (printed on a box or case).

3.Use of the “Developers” mode:

Turn on the Bluetooth HCI log in the developer settings, and this creates a connection error log file that can be analyzed through applications like Bluetooth Scanner.

7.Firmware update for QCY headphones

If your QCY is bugged (self-disabled, bad-sounding), you may need a firmware update. For most models, this is done through the official QCY app:

1. Put the headphones on the phone.
2. Open the QCY app and go to the "Update".
3. If a new version is available, click “Update” and wait until it is completed (don’t turn off the headphones!).

For models without support OTA-updates (e.g. updates, QCY T1) firmware can be installed manually through the PC using the utility QCY Note: Unofficial firmware can ruin headphones – only use files from the official website QCY.

After the update, reset the headphones to the factory settings (press the buttons for 15 seconds) and connect again.
