The combination of affordable price and decent quality has made QCY wireless headphones one of the most popular accessories on the market. Owners of Xiaomi, Redmi and Poco smartphones often choose this brand due to stable operation and good integration with the MIUI or HyperOS operating system. The pairing process is usually not difficult, but there are nuances that can be confusing for a beginner.
Proper initial configuration ensures not only a stable connection, but also the correct operation of all control functions. In this article, we will discuss in detail the connection algorithm, work with a proprietary application and how to solve typical problems. You will learn to configure the equalizer, update the firmware and use all the features of your TWS-headphone.
Before you start pairing, make sure that both headphones are charged enough to perform the procedure. Low charge can lead to unstable operation of the Bluetooth module or interruption of the setup process. It is also recommended to temporarily turn off Wi-Fi, as in some cases, 2.4 GHz frequencies can cause interference, although modern Xiaomi smartphones are able to effectively separate them.
Primary pairing of devices via Bluetooth
The first step is to activate the pairing mode on the headphones themselves. Unlike wired models, QCY requires you to switch to search mode before first use or after resetting. For most models, such as the QCY T13, T17 or HT05, you need to remove both earbuds from the charging case.
If the device has not previously been paired with other gadgets, it will automatically go into the standby mode of connection, as signaled by a flashing indicator. In the case when the headphones were connected to another phone, it may require prolonged retention of touch areas. This usually takes about 5-7 seconds until the indicators start flashing white or blue at a high frequency.
On a Xiaomi smartphone, open the settings and go to the Bluetooth section. Make sure the activation slider is in the "On" position. The system will start scanning available devices in range. The "Available Devices" list should show the name of your model, for example, QCY T13 or QCY HT01.
☑️ Checking before connection
Click on the device name in the list on your smartphone screen. The system can request a pairing confirmation — click OK or Connect. Once you successfully connect, the status will be marked "Connected," along with the charge levels of the left and right earphones, and the audio profile will activate automatically, and you will hear the characteristic beep in the headphones.
⚠️ Note: If two identical device names appear in the Bluetooth list, choose one that doesn’t have any additional characters or suffixes, or try removing both and repeating the procedure again.
Using the QCY application for advanced customization
The basic connection allows you to listen to music, but to unlock the full potential of the headset, you need to install a branded QCY app. This software is available on Google Play and is often found in the GetApps store on Xiaomi smartphones.
Once installed, launch the app and allow access to location and Bluetooth. These permissions are critical because they are required in Android to scan and maintain peripherals. The main menu will display your headset with the current charge level. Click on the device icon to enter the settings menu.
In Settings, you will find options for reassigning touch buttons. You can set up single, double and triple touches for left and right earphone separately. Track switching, voice assistant activation, volume control, or low latency game mode are available.
Secret functions of the app
The equalizer section deserves special attention, where you can choose from one of the preset sound profiles or create your own by adjusting the frequencies. Game Mode, which reduces the latency of sound transmission, which is critical in shooters and rhythm games, can slightly increase power consumption for gamers.
Specifics of working with MIUI and HyperOS
The MIUI shells and Xiaomi’s new HyperOS have an aggressive power management system that can sometimes interrupt background applications, including the QCY app. To ensure that the battery widget always displays correctly and the settings are not reset, you need to configure the permissions correctly.
Go to Settings → Applications → All Apps. Find the QCY app on the list. Go to Activity Control (or Battery) and select No Limits, which will prevent the system from killing the application process to save energy.
| Setup parameter | Recommended value | Impact on work |
|---|---|---|
| Auto-start | Included. | The application is launched together with the system |
| Activity monitoring | No restrictions. | Prevents the Bluetooth service from being disabled |
| Permits | Everything (Location, Phone, Storage) | Required for battery widget and calls |
| Displaying on top of others | Permitted. | Allows the pop-up windows to work properly |
It's also worth checking the widget settings. On the Xiaomi desktop, you can add a Battery Charge widget or a special QCY widget if it's supported by the firmware version. This will allow you to see the charge level without opening the app every time. The widget updates in real time and shows the connection status.
Setting up sensory control and gestures
Sensory management is one of the key features of modern TWS-By default, the settings may not match your habits, so changing them through the app is a must. The interface is usually intuitive and divided into left (L) and right (R) channels.
The left earphone often has a voice assistant or mode switching function (e.g., noise reduction or transparent mode). The right earphone has a music playback function. The triple tap is usually reserved for an assistant call or switching between microphone modes.
You can turn off unnecessary gestures in the app, for example, if you accidentally hit your headphone when you're straightening your hair, double tapping can pause the track. By removing this setting, you avoid unnecessary interruptions. You can also set up a sensor delay setting to help cut off random touches.
⚠️ Warning: Changes to the control settings are only applied after you click on the "Save" or "Apply" button in the application. Do not close the application until you have completed synchronization with headphones.
Update to the firmware of QCY headphones
The manufacturer regularly releases software updates to fix bugs and improve connection stability. Notification of a new version can appear in the QCY app automatically when you connect. Ignoring these updates is not recommended, as they often contain patches for compatibility with new versions of Android.
The Firmware Update requires a stable Internet connection and a battery charge of at least 50%. During the upgrade, the headphones can make strange sounds or interrupt the connection - this is normal behavior.
To start the update, go to the device profile in the app and look for the Firmware Upgrade or Software Upgrade. If a new version is available, a download button will appear. After downloading, the firmware process will begin, the progress of which will be displayed as a percentage.
💡
Regular firmware updates are the most effective way to fix problems with audio and video desynchronization or sudden shutdowns.
Resolving Connection Problems
Even if all instructions are followed, there can be technical difficulties, most often users are faced with a situation where the phone sees the headphones but does not connect, or the sound comes from only one channel, often solved by simply resetting the settings to the factory.
For reset (Factory Reset) usually need to place the headphones in the case, leave the cover open and pinch the touch areas on both headphones at the same time on the case. 10-15 The indicators should flash several times to signal a reset, then remove the device from the Bluetooth list on the phone and do the pairing again.
If the audio is interrupted or of poor quality, check if the Traffic Saving mode is activated in the Bluetooth codec settings. Also, the problem may be Wi-Fi overload. Try to switch the router to 5 GHz, freeing up the 2.4 GHz band for a Bluetooth connection.
💡
If one earphone is not charging in the case, wipe the contacts on the headphone and in the case with a dry cotton swab.Oxidation or dust often interfere with charging.
