Modern smartphone users are increasingly abandoning wires in favor of freedom of movement, and owners of brand devices Samsung are no exception. Correctly setting up your audio device allows you to unleash the full potential of your gadget, providing clear sound and a stable connection without lag. The pairing process may seem simple, but there are many nuances that affect the quality of listening to music and comfort during calls.
In this article we will analyze in detail the algorithm of actions for owners of Android interface One UI, consider hidden developer settings to improve the sound and answer frequently asked questions that arise when using the headset. You will learn how to make advanced codecs work and what to do if the phone does not see the headphones.
Initial pairing and detection mode
Before you start setting up, you need to switch your Bluetooth headphones to visibility mode. Most modern models activate this mode automatically when first turned on, but manual intervention is often required to reconnect to a new device. This is usually done by long-holding the power button or a special pairing button until the indicator starts blinking blue or red-blue.
On a Samsung smartphone, the process is as follows: open the quick settings panel by swiping from top to bottom and make sure that the icon Bluetooth is highlighted active color. For more detailed control, go to the main settings menu via the gear icon. Find the section Connections and select Bluetooth.
In the list of available devices that opens, your audio equipment should appear in the "Available devices" block. Click on the model name to begin the pairing procedure. If the system prompts PIN code, enter the standard combination 0000 or 1234, although modern security protocols often bypass this step by using confirmation of the encryption key in the background.
⚠️ Note: If you have previously connected these headphones to another phone, they may automatically try to connect to it, ignoring your Samsung. In this case, temporarily disable Bluetooth on your old device or delete the headphone profile from its memory.
☑️ Checklist for successful connection
Managing audio codecs and sound quality
Standard Android settings often limit the sound quality of the codec SBCwhich provides only basic sound. Owners of Samsung phones can access more advanced compression algorithms, such as aptX, LDAC or SSC (Samsung Scalable Codec), but this requires activation of the developer menu.
To access these settings, go to the About phone section in the main settings. Find the item Software information and quickly click 7 times on the line Build number. After a message appears stating that you have become a developer, return to the main settings menu - a new section will appear at the very bottom of the list Developer options.
Inside this menu, scroll down the list to the "Network" or "Multimedia" block. Find the item Bluetooth audio codec. By clicking on it, you will see a list of available formats. Choosing a higher quality codec, such as LDACcan significantly improve high frequency detail, but note that this increases battery drain and may require a stable signal without interference.
Why does the codec reset to SBC?
If the connection unstable or the distance to the phone is long, the system will automatically switch to the basic SBC codec to prevent audio dropouts. This is the standard behavior of the Bluetooth protocol.
| Codec | Bitrate (kbit/s) | Quality | Compatibility |
|---|---|---|---|
| SBC | 328 | Basic | All device |
| aptX | 352 | Good | Android, Qualcomm |
| LDAC | 990 | Hi-Res | Android 8.0+ |
| SSC | 512 | Optimal | Samsung Galaxy Buds |
Setting up gestures and touch controls
Control playback and calls directly from the headphones significantly improves usability. On Samsung smartphones, this function is integrated deeply into the system, especially if you use original brand accessories, such as Galaxy Buds. For third-party models, settings may be limited to standard Android actions.
Go to menu Settings → Connections → Bluetooth. Click on the gear icon next to the connected device. Here you will find the item Touches and holds or Gestures. The interface One UI allows you to flexibly reassign actions: single tap, double, triple or long press.
You can adjust the left and right bowls independently of each other. For example, it is convenient to assign volume control (swipe up and down) to the left side, and switching tracks to the right side. This eliminates the need to take the phone out of your pocket every time.
- 🎵 Double tap: Pause or play a track
- 🔊 Swipe up/down: Adjust the volume level
- 📞 Long press: Activate the voice assistant or noise reduction
If standard gestures do not work for third-party headphones, try installing the official application of the headset manufacturer from the Google Play Store - finer control settings are often available there.
Dual device function and multi-connection
The Samsung ecosystem offers the unique ability to simultaneously connect one pair of headphones to two different signal sources. This feature, known as Dual Audio (in the context of dual-pair output) or simply multi-connection (for one pair to two phones), is extremely useful in everyday life.
To activate the ability to connect to two sources (if your headphones support this technology in hardware), you do not need to look for special switches in the Bluetooth menu. It is enough to simply complete the pairing procedure with a second device without deleting the profile from the first. Modern chips in headphones themselves control the priority of the incoming signal. However, if you want to broadcast sound from one Samsung phone directly to wireless headphones to listen to a movie with a friend, use the function in the Bluetooth quick access panel or in the media output settings. Select the option
However, if you want to stream audio from one Samsung phone directly to two different pairs wireless headphones, to listen to a movie with a friend, use the Additional options in the Bluetooth Quick Access Toolbar or Media Output Settings. Select an option Connect a second audio device and pair the second headset.
⚠️ Attention: Audio output function to Two pairs of headphones may not work correctly with third-party models that are not certified for the Samsung ecosystem. In such cases, audio desynchronization is possible.
Optimizing the operation of the microphone and calls
The quality of voice transmission during a call directly depends on the microphone settings and noise reduction algorithms. The Samsung interface often has an activated function Absolute volume levelthat synchronizes the volume of the phone and headset. Sometimes this leads to the fact that the interlocutor hears you too quietly or, conversely, with distortion.
If you encounter problems with calls, check the settings in the section Developer optionsthat we mentioned earlier. Find item Disable absolute volume level. Try changing its state (turn it on or off) and restart Bluetooth. This action often solves the problem of a quiet microphone.
It is also worth paying attention to the application Sound and vibration. In some models, a setting is available Separate application sound, which allows you to direct the sound of the call to the phone speaker, and leave the music in the headphones, or vice versa. This is useful if you are waiting for an important call while listening to a podcast.
Settings → Sound and vibration → Separate application sound → OnFor owners Galaxy Buds Pro or newer models have a feature that automatically switches between active noise cancellation and transparency mode when starting a call. Make sure that this option is activated in the application Galaxy Wearableso as not to miss the words of the interlocutor due to isolation from the outside world.
Solving common connection problems
Despite the stability of Android, users sometimes encounter a situation where the phone sees the headphones, but does not connect, or the connection is constantly broken. The first step should always be clearing the Bluetooth services cache, not just restarting the phone.
Go to Settings → Applications. Click on the three dots in the upper corner and select Show system applications. Find it in the list Bluetooth (do not confuse it with Bluetooth settings). Go to the section Memory and click the button Clear cache. If this does not help, try pressing Delete data, but remember that this will reset all saved device pairs.
Another common cause of failures is a conflict between Wi-Fi and Bluetooth frequencies, since they operate in the 2.4 GHz band. If you are using a home Wi-Fi network at this frequency and are near the router, try switching your phone to mobile data or a 5 GHz network to check the stability of the connection.
- 🔄 Reboot both devices: both the phone and the headphones
- 🗑️ Remove the device from the list of paired ones and connect again
- 📶 Move away from sources of strong radio interference (microwaves, routers)
In 90% of cases, the problem of an unstable connection is solved by completely rebinding the device after clearing the cache of the Bluetooth system service.
Why don’t the headphones charge in the case of a Samsung phone?
The function of wirelessly charging headphones from a phone (Wireless PowerShare) may not work if a thick case is installed on the back cover of the smartphone. Remove the case and make sure the center of the case is aligned with the center of the back of the phone. Also make sure that the phone's charge level is at least 30%.
How to disable voice prompts in English?
Voice notifications about the charge level or connection status are often built into the firmware of the headphones themselves, not the phone. Try resetting the headphones to factory settings (usually by holding the buttons on the case for 10 seconds) or check the settings in the headset manufacturer's proprietary application.
Is it possible to connect more than two devices at the same time?
The standard Bluetooth protocol and the One UI interface support active audio transmission to a maximum of two devices at the same time. Connecting a third device is only possible after disconnecting one of the current ones, with the exception of specific scenarios with smart watches that work as a repeater.
What to do if there is sound, but it is very quiet?
Check whether the "Mono Audio" mode is enabled in Accessibility, as it may reduce the overall volume. Also make sure that the media volume limiter is not activated in the developer settings, and check the physical cleanliness of the headphone speaker grids.
