How to connect QCY headphones to Xiaomi phone via Bluetooth: full instruction

Why don’t the QCY headphones connect to Xiaomi the first time?

QCY wireless headphones (particularly the popular QCY T1C, QCY T13, QCY HT05 or QCY TWS) often become a headache for Xiaomi, Redmi and POCO smartphone owners due to pairing issues. Unlike the original Mi/Airdots accessories, which connect to the Xiaomi ecosystem automatically, third-party brand headphones require manual tuning - and here comes the complexity.

The main reasons for failure: outdated versions of Bluetooth (for example, QCY T1C runs on Bluetooth 5.0, and budget models Redmi can use 4.2), conflicting sound profiles (A2DP vs HFP), or bugs in the firmware MIUI. In this article, we will analyze the step-by-step connection taking into account all the nuances, and also solve typical problems - from the lack of sound to permanent connection breaks.

Important: If your QCY headphones have already been paired with another device (for example, a laptop or tablet), they must first be reset to factory settings - otherwise Xiaomi may not see them in the list of available devices.

1. Preparing QCY headphones for connection

Before pairing with a Xiaomi phone, make sure the QCY headphones are ready to connect.Most models (like the QCY T13 or QCY HT07) automatically go into search mode when first turned on, but after reconnecting, may require manual activation.

To put the headphones in pairing mode:

• 🔋 Charge headphones to at least 30% (the indicator on the case should burn white or blue – red means low charge).
• 🎧 Get both headphones out of the case - some models (e.g, QCY T1C) Bluetooth not activated if one earphone remains in the case.
• 🔄 Hold the power button for 5-7 seconds until the indicators start flashing alternately red and blue (search mode). QCY TWS You may need to hold the touch panel.

If the lights don't flash, try resetting your headphones to factory settings (instructions in the next section) and check if the button case is blocking, a common problem with the QCY HT05.

2.Reset QCY headphones to factory settings

If the QCY headphones have previously been connected to another device or are not working smoothly, they must be reset.

After reset, the QCY headphones will automatically go into pairing mode. If this does not happen, repeat the procedure or check the battery power - at a level below 10%, the reset may not work.

⚠️ Note: After reset, all previous connections will be deleted, including call history and equalizer settings (if supported). QCY T13 firmware also resets updates – they will have to be installed again through the official application.

3. Step-by-step: Connecting QCY to Xiaomi via Bluetooth

Now, the manual is universal for all Xiaomi, Redmi and POCO smartphones based on MIUI 12-14 or HyperOS, but there may be nuances depending on the firmware version.

Act on the algorithm:

1. Open Bluetooth settings on your phone: Go to Settings → Connections and Sharing → Bluetooth. Activate the Bluetooth slider (should turn blue).
2. Start a device search: Click Device Search (or Add a new device) and the name of your headphones will appear on the list of devices you find (e.g., QCY-T13-L or LE-QCY-HT05).
3. Connect your headphones: tap the device name in the list. Confirm pairing if you request (some Xiaomi models require you to enter the device name). PIN-code - usually 0000 or 1234).

If the headphones don’t appear on the list, try:

• 🔄 Reboot the phone’s Bluetooth module (turn off/on Bluetooth or restart your smartphone).
• 📱 Update MIUI Up to the latest version (old firmware has bugs with Bluetooth 5.0).
• 🎵 Disable other audio devices (columns, smartwatches) that may conflict.

💡

If your Xiaomi doesn’t see QCY, try connecting the headphones to another phone (like Android 10+) and then returning them to pairing mode.

4.Problem fix: Headphones plugged in, but no sound

Frequently, QCYs are successfully paired with Xiaomi, but the sound only goes through the phone's speaker or is interrupted.

For QCY T13 and later, check the settings in the QCY App (available on Google Play).

• 🎛️ Set up an equalizer (Bas profiles, Clear Sound", "3D-effect").
• 🔊 Adjust the noise reduction level (if supported).
• 🔋 View the level of charge of each headphone.

⚠️ Note: On Xiaomi smartphones with MediaTek processors (for example, Redmi Note 11 or MediaTek) POCO M4 Pro) may experience increased sound delay when using the codec AAC. In this case, you must choose SBC developer-setting.

5. Connection Optimization: How to Reduce Bluetooth Breaks

If the QCY headphones are permanently disconnected from Xiaomi, the problem may lie in the power saving settings or interference.

1. Turn off battery optimization for Bluetooth:

• Go to Settings → Applications → Application Management → System Applications.
• Find Bluetooth and turn off Battery Optimization.

2. Set the connection priority:

• In Bluetooth settings, tap on the icon ⚙️ near QCY.
• Select Priority Connection (if available).

Reduce interference:

• 📶 Turn off Wi-Fi at 5GHz – it can conflict with Bluetooth 5.0.
• 📱 Don’t keep your phone in your pocket next to your headphones – Xiaomi’s case can shield the signal.
• 🔋 If the problem occurs when the phone is low (below 20%), connect the charger — MIUI Automatically reduces Bluetooth power to save energy.

6. Features of connection for different models Xiaomi

MIUI firmware and the Qualcomm Snapdragon vs MediaTek hardware platform affect the stability of Bluetooth.

📱 Xiaomi 13/14 series (Snapdragon 8 Gen 2/3):

• Support Bluetooth 5.3 with AAC, aptX Adaptive, LDAC codecs.
• For QCY T13, it is recommended to choose aptX (less lag in games).
• Connection problems are solved by updating MIUI to the latest version.

📱 Redmi Note 12/11 series (Snapdragon 4 Gen 1 / MediaTek Helio G99):

• MediaTek may not have LDAC – use AAC.
• Frequent communication breaks are solved by disabling Double Bluetooth audio in the audio settings.

📱 POCO F5/X5 series:

• HyperOS has LE Audio activated by default – turn it off for stable QCY operation.
• For models with an IR Blaster (Infrared Port), you may need to turn it off in Settings → Connections → Infrared Port (interferes with Bluetooth at 2.4 GHz).

💡

On Xiaomi smartphones with MediaTek processors (such as the Redmi 10C or POCO M5), QCY headphones can only connect in mono mode (one earpiece). To activate the stereo, upgrade to MIUI 14+ or use the Bluetooth Auto Connect app.

7. Alternative ways to connect (if Bluetooth does not work)

If standard pairing fails, try workarounds:

🔌 Method 1: Use of the Bluetooth Auto Connect application

• Download the app from Google Play.
• Add QCY to the list of trusted devices.
• Activate the option of Forced Connection.

📱 Method 2: Connecting through Developer Mode

• Activate Developer Mode (7 taps according to MIUI version).
• Go to Settings → Additional → Developer settings.
• Turn on Bluetooth debugging and always enable detection.
• Try reconnecting.

🔄 Method 3: Reset network settings on Xiaomi

• Go to Settings → System → Resetting of settings → Resetting of network settings.
• After rebooting, repeat the pairing.

⚠️ Warning: Resetting network settings will delete all saved Wi-Fi passwords and data VPN. Before the procedure, write down important logins.
