Modern smartphones, such as Honor 9X, are equipped with advanced wireless communication modules that allow you to enjoy high-quality sound without unnecessary wires. However, the first pairing process often raises questions among users, especially if you have previously used devices with outdated versions Bluetooth or other operating systems. Correctly setting up the data transmission channel is critical not only for listening to music, but also for stable operation of the microphone during calls.
In this article we will analyze in detail the algorithm of actions necessary to successfully synchronize your gadget with any compatible headset. You will learn how to activate the search mode on different types of devices, what settings are hidden in the engineering menu and how to avoid common mistakes that lead to connection breaks. The key factor for a successful connection is to simultaneously activate the pairing mode on the headphones and scanning on the phone within the first 30 seconds. Let's move on to the practical implementation.
Preparing devices for pairing
Before you start searching for devices in your phone settings, you need to make sure that your headset is in the correct state. Many users make the mistake of simply turning on their headphones, which is not enough for their smartphone to detect them. The device should enter a special visibility mode, which is often activated by holding the power button or a dedicated pairing key.
Check the battery level on both devices. Low battery power in the headphones may cause them to be unable to support the signal strength needed to establish a connection, or the process will be interrupted during the authentication phase. Make sure that the module Honor 9X is turned on on your smartphone Bluetooth, but do not start the search yet if the headset is not yet ready.
There are several ways to put the headphones into discovery mode, depending on their design and manufacturer. Most often, you need to hold down the power button for 5-7 seconds until the indicator starts flashing in two colors (usually red and blue) or quickly flashing in one color. This is a signal that the device is broadcasting its identifier over the air.
If the headphone indicator flashes slowly or is constantly on, it means that pairing mode is not activated. Try turning them off and repeating the procedure, holding the button longer.
Step-by-step guide for connecting through settings
After preparing the headset, you can begin setting up the smartphone itself. The interface of the EMUIshell installed on Honor 9Xis intuitive, but has its own peculiarities in the menu layout. Follow the algorithm below to be sure to find and connect your device.
First, unlock your phone screen and go to the main application menu. Find the Settings icon and open it. In the list of parameters that opens, you will need a section responsible for wireless connections. In some firmware versions it may be called simply “Bluetooth”, in others it may be part of the “Device Connections” group.
Activate the switch Bluetoothif it is disabled. The system will automatically begin scanning available devices within range. Once you see your headset's name in the Available Devices list, click on it. The phone will ask for confirmation for pairing, and after a few seconds the status will change to “Connected.”
☑️ Honor 9X connection algorithm
Sometimes the system may ask you to enter a PIN code to confirm the security of the connection. Standard combinations for most devices are 0000 or 1234, however, modern models often do without this step, using a secure protocol SSP (Secure Simple Pairing). If a code is requested and you do not know it, refer to the headphone manufacturer's instructions.
Setting the profile and sound quality
After a successful connection, it is important to make sure that the phone is using the correct data transfer profile. For music, the profile A2DP (Advanced Audio Distribution Profile) is used, providing high quality stereo sound. For calls, the profile HFP (Hands-Free Profile) is used. If the sound is monaural or of poor quality, the wrong mode may be selected.
In the settings of the connected device on Honor 9X you can manually manage access rights. Click the gear icon or arrow next to the name of the connected headphones. Here you will see toggles for Sound and Calls. Make sure both items are active if you plan to use the headset universally.
Sound quality also depends on the codec used. The smartphone supports various compression algorithms, such as SBC, AAC and sometimes more advanced aptX or LDAC, if the headphone hardware allows it. By default, the system selects the most compatible option, but if you wish, you can experiment with the settings in the developer menu.
How to enable advanced codecs?
To access the selection of codecs, you must activate “Developer Mode”. Go to “About Phone” and quickly tap 7 times on “Build Number”. Then, in the System → Developer Options menu, find the Bluetooth Audio section and select your preferred codec.
It is worth noting that using high-definition codecs may slightly increase audio latency when watching videos or playing games. If you notice desynchronization of audio and video, try switching to the standard codec SBC in the same developer settings.
Multiple device management and history
Smartphone Honor 9X allows you to save information about previously connected devices. This is convenient if you use several pairs of headphones: for home, for sports and for work. You don't need to go through the full pairing procedure every time; Just turn on Bluetooth on both devices and they will connect automatically.
In the Bluetooth menu you will see a list of “Paired devices”. Here you can manage priorities and delete old entries. If your phone tries to connect to headphones that are currently turned off or are far away, this can slow down the search for new devices. It is recommended to remove from the list gadgets that you no longer use.
To switch between devices without completely disconnecting, just click on the desired device in the list of paired ones. The system will terminate the current connection and establish a new one. However, simultaneous sound transmission to two pairs of headphones (Dual Audio function) on this model may be limited by firmware versions and transmitter power.
| Device type | Connection priority | Signal stability | Power consumption |
|---|---|---|---|
| Over-ear headphones | High | Excellent | Average |
| In-channel (TWS) | Average | Good | Low |
| Automotive system | Low | Depends on the car | High |
| Smart watches | High | Stable | Minimum |
Automatic reconnection only works if the headphones were previously paired and are within range. New devices always require manual initiation.
Typical problems and solutions
Even if all instructions are followed, users may encounter difficulties. The most common problem is that the phone sees the device but cannot complete pairing, giving a timeout error. This is often due to the fact that the headphones are already connected to another gadget, for example, to a tablet or laptop, located nearby.
Another common situation is intermittent sound or constant disconnections. This may be caused by radio interference from Wi-Fi routers, microwave ovens, or other signal sources in the 2.4 GHz range. Try to move away from the source of interference or temporarily turn off Wi-Fi on your phone for diagnostics.
- 📶 Weak signal: Make sure that there are no thick walls or metal barriers between the phone and the headphones that shield the signal.
- 🔋 Battery drain: A critically low charge in the headphones can lead to a decrease in transmitter power and communication failures.
- 🔄 Bluetooth cache: Clearing the Bluetooth service cache in application settings can resolve software conflicts.
- 📱 Reboot: A simple reboot of both devices often eliminates temporary failures in the stack protocols.
If none of the methods helps, the problem may lie in incompatibility of protocol versions. Outdated headphone models may not work well with new energy saving standards implemented in Android 10 and higher, on which it is based Honor 9X.
Advanced settings and developer mode
For advanced users who want to get the most out of the audio system, it is possible to fine-tune Bluetooth settings. Access to these functions is hidden in a special section “For Developers”. You can activate it by clicking seven times in a row on the build number in the “About phone” section.
In the menu that opens, find the section dedicated to network settings. Here you can change the maximum data packet length (AVRCP), which affects the transmission speed of track metadata (album covers, titles). There is also an option to disable the absolute volume level, which is useful if the volume on the phone and headphones is out of sync.
⚠️ Attention: Changing settings in developer mode may lead to unstable system operation or increased battery consumption. Revert to default values if you notice performance degradation.
Particular attention should be paid to the Ping Timeout setting. Increasing this setting may help in situations where the connection drops when the phone wakes from sleep mode. However, too large values may result in the phone not detecting the headphone disconnection in time.
If the sound has become quieter after updating the firmware, try disabling the “Disable absolute volume level” option in the developer menu and reboot the phone.
Features of working with different versions of Android
Smartphone Honor 9X was initially supplied with one version of the operating system, but could receive updates during operation. The interface and operating logic of the Bluetooth stack may differ slightly depending on the installed version EMUI or the transition to services without Google (in later models, although the 9X is usually equipped with GMS).
In earlier versions of the firmware, the settings menu could be more simplified, without detailed information about the battery charge of the connected headphones in the notification shade. In updated versions, this feature appears automatically with support from the headset. If the charge indicator is not displayed, try updating the phone software.
It is also worth considering that power saving policies work differently in different versions of Android. Aggressively closing background processes can cause music to stop when the screen is locked. To avoid this, add your music player to the list of protected applications in the battery settings.
⚠️ Attention: The settings interface may vary depending on the firmware version and regional modification of the device. If you do not find the item described, use the settings search by entering the keyword “Bluetooth.”
Regular software updates provide not only new features, but also fixes for vulnerabilities in wireless security protocols. It is recommended to check for updates at least once a month through the menu System → Software update.
Frequently asked questions (FAQ)
Why does the phone not see the headphones, although they are turned on?
Most likely, the headphones are not set to pairing. Simply turning on the power does not make the device visible to newer phones. Press and hold the power button or dedicated connection button until the indicator blinks. Also make sure that they are not connected to another device nearby.
Is it possible to connect two pairs of headphones at the same time to Honor 9X?
Technically, the Bluetooth module supports multiple connections, but the stock firmware EMUI most often allows you to output sound to only one playback device at a time. The second pair can be connected for the call profile, but not for music, if the Dual Audio function is not explicitly stated in the specifications.
How to reset Bluetooth settings on your phone?
Go to Settings → System → Reset. Select "Reset network settings" or "Reset Wi-Fi, mobile networks and Bluetooth settings." This will delete all saved devices and return network settings to factory defaults without affecting personal data.
Why does the sound in headphones lag behind the video?
This phenomenon is called latency. This is typical for high quality codecs or when there is strong interference. Try switching the codec to SBC in the developer menu or bringing the phone closer to the headphones. Some video players have a function for manually adjusting the audio delay.
Does the case affect the quality of communication?
Yes, thick cases, especially those containing metal inserts or magnets, can shield the signal from the antenna located in the smartphone body. If you notice problems with communication only in the case, try removing it and checking the stability of the connection.
