Connecting a Bluetooth headset to Android for calls: complete guide

Wireless headsets have long become an integral part of everyday life: they allow you to talk on the phone without holding it in your hands, listen to music wirelessly, and even control voice assistants. However, many users Android face difficulties when connecting a headset for the first time - the device does not find the headphones, the sound comes through the phone speaker, or the microphone does not work during a call. This article will help you understand all the nuances: from basic synchronization to fine-tuning for ideal sound.

We will consider not only the standard connection procedure through the menu Settings, but also alternative methods (for example, through Google Assistant or manufacturer utilities like Samsung Wearable or Sony Headphones Connect). We will pay special attention to common problems: why the headset connects as a “media device” but does not transmit voice during a call, how to reset Bluetooth settings on your phone, and what to do if the headphones turn off after 5 seconds. At the end you will find an FAQ with answers to frequently asked questions - from compatibility of budget headsets to features of working with Android 14.

1. Preparation: checking compatibility and charging devices

Before you start connecting, make sure that your headset and smartphone compatible are using Bluetooth protocols. Most modern headphones (including models from JBL, Sony WH-1000XM5, AirPods or Xiaomi Buds) support profiles HFP (for calls) and A2DP (for music), but older devices (for example, headsets before 2018) can only work with HSP - stripped version of the profile for voice.

To avoid problems:

• 🔋 Check the charge of the headset: most models require a minimum 20-30% charge for a stable connection. The indicator on the headphones usually flashes red when the battery level is low.
• 📱 Update the firmware on your smartphone: Settings → System → Software update check that the Android version is up to date. For example, Android 13+ improved support for LE Audio i LC3 new standards for wireless audio.
• 🔍 Make sure the headset is not connected to another device (laptop, tablet). Some models (for example, Bose QuietComfort) automatically reconnect to the last used gadget.

⚠️ Attention: If your smartphone was released before 2019 (for example, Samsung Galaxy S8 or Xiaomi Redmi Note 5), it may not support Bluetooth 5.0+. In this case, there may be problems connecting headsets that require low latency (for example, for games or videos).

To check the Bluetooth version on your phone:

1. Open Settings → About phone → About Software.
2. Find the line "Bluetooth version" (on some models - in the "Hardware information" section).

2. Standard connection through the Android settings menu

The most reliable way to connect a headset is through the system menu Bluetooth. The instructions are universal for all versions of Android (from Android 8 Oreo to Android 14), but the interface may differ slightly on smartphones of different brands (Samsung One UI, Xiaomi MIUI, Google Pixel etc.).

Step-by-step guide:

1. Enable pairing mode on the headset. Usually for this you need to hold down the power button on 3-5 seconds until the indicator starts flashing blue/white (open the case cover). For models with touch controls (for example, AirPods — open the cover of the case). For models with touch controls (such as Sony WF-1000XM4), you may need to hold the touchpad.
2. On your phone, open Settings → Connected devices → Bluetooth (or Settings → Bluetooth and network on Xiaomi).
3. Activate the slider Bluetooth (if it is turned off) and wait until the phone finds available devices.
4. B in the list of found devices, select the name of your headset (for example, "Galaxy Buds2 Pro" or "JBL Tune 510BT").
5. Confirm pairing on the phone and (if required) on the headset - some models require you to press a button to confirm.

After successful connection, a status will appear in the list of devices "Connected for media and calls" (or similar). If instead This is what you see "Connected only for media", which means that the profile HFP has not been activated - we will talk about this in the section on solving problems.

3. Alternative connection methods

If the standard method did not work or you want to use additional functions (for example, customizing gestures or an equalizer), try alternative connection options.

Method 1: Through the manufacturer's application

Many brands release proprietary utilities to configure their headsets:

• 🎧 Samsung Galaxy Buds → Galaxy Wearable (available in Google Play).
• 🎧 Sony WH/WF series → Sony Headphones Connect.
• 🎧 JBL, Harman Kardon → JBL Headphones or Harman Audio Control.
• 🎧 AirPods → although officially they are intended for iPhone, they can be connected to Android manually (but you will lose some functions, for example, automatic switching between devices).

Example of connection via Galaxy Wearable:

1. Install the application from Google Play.
2. Open it and follow the instructions on the screen - the app itself will find the headset in pairing mode.
3. After connecting, you can configure gestures, equalizer, turn on ANC (active noise reduction) or "For calls" mode.

Method 2: Via Google Assistant

If your phone supports Google Assistant (most devices do Android 6.0+), you can connect the headset by voice:

1. Activate the assistant by command "Okay, Google" or holding the button Home.
2. Say: "Connect Bluetooth headset".
3. The assistant will turn on Bluetooth and ask you to select a device from the list.

⚠️ Attention: Voice connection may not work if the headset has already been paired with another device and has not come out of standby mode. In this case, first reset its settings (usually by holding the power button for 10+ seconds).

Method 3: Via NFC (for supported devices)

Some headsets (for example, Sony WH-1000XM4 or Bose QuietComfort 45) support NFC —near-range wireless communication technology. To connect:

1. Turn on NFC on your phone (Settings → Connected devices → NFC).
2. Touch the back of the phone to the special mark on the headset (usually marked logo NFC).
3. Confirm pairing on the smartphone screen.

4. Setting up the headset for calls

Even after successful connection, the headset may not transmit voice during a call. This happens if:

• 🔇 The correct one is not selected in the phone settings. Bluetooth profile (must be HFP or HSP, and not just A2DP).
• 🎤 The headset microphone is muted manually or blocked by the application (for example, WhatsApp or Zoom can ignore external microphones).
• 📞 The phone has the "Speaker" or "Phone microphone only" mode activated.

How to set up the headset for conversations:

1. During a call, tap icons Audio (usually in the top bar of the call screen) and select Bluetooth headset.
2. Check the microphone settings:

   Settings → System → Sound → Sound input → Microphone

   Make sure that the headset microphone is selected (for example, "Sony WH-1000XM5 Mic").

3. For some models (for example, Galaxy Buds) there is a separate "Call mode" switch in the proprietary application - turn it on.

Problem	Possible reason	Solution
Sound comes through the phone, not the headset	Profile not selected HFP or the headset is connected only as a “media device”	In the Bluetooth settings, click on the name of the headset → "Use for calls"
The interlocutor cannot hear you	The headset microphone is muted or blocked	Check the microphone settings in Settings → Sound → Audio input
The headset turns off during a call	Weak Bluetooth signal or conflict with other devices	Disconnect other Bluetooth devices, restart the phone

5. Solving common problems

Even after proper connection, problems may occur. Let's consider the most common of them and how to fix them.

Problem 1: The headset is connected, but the sound comes through the phone

This occurs if:

• An audio device is not selected in the call settings.
• The headset is connected only using the profile A2DP (for music), and not HFP (for calls).
• The mode is activated on the phone "In dynamics."

Solution:

1. During a call, click on the icon Audio (usually at the top of the screen) and select Bluetooth headset.
2. In the Bluetooth settings, click on the name of the headset → enable the option "Use for calls" (on some phones — "Connect as a telephone headset").
3. Restart the phone and headset.

Problem 2: The interlocutor does not hear your voice

Reasons:

• The headset microphone is disabled in the settings.
• The wrong Bluetooth profile is used.
• The headset is physically damaged (for example, the microphone is dirty).

Solution:

1. Check your microphone settings:

   Settings → System → Sound → Audio Input → Microphone

   Select your headset microphone (for example "JBL Tune 510BT Mic").

2. Disconnect and reconnect the headset.
3. Try using it with another device (for example, a laptop) to check the functionality of the microphone.

Problem 3: The headset keeps disconnecting

Possible reasons:

• Weak Bluetooth signal (for example, if the phone is in your pocket and you are far from it).
• Conflict with other Bluetooth devices (for example, a smart watch or speaker).
• Android energy-saving settings turn off Bluetooth in the background.

Solution:

1. Disable other Bluetooth devices.
2. Add the headset to the "Battery optimization exceptions" list:

   Settings → Battery → Battery optimization → All apps → Find Bluetooth → Disable optimization

3. Update the headset firmware (via the manufacturer's proprietary application).

What to do if the headset is not detected by the phone?

1. Make sure the headset is in pairing mode (the indicator is flashing blue/white).

2. Restart Bluetooth on your phone: turn it off and on again in the settings.

3. Reset the network settings on your phone:

Settings → System → Reset → Reset Wi-Fi, mobile network and Bluetooth settings.

4. Check the headset with another device - if it does not connect there, the problem is in the headphones (may need replacement).

6. Optimizing sound for calls

To improve the sound quality during calls, you can configure several parameters:

Setting the Bluetooth codec

Android supports several audio codecs for Bluetooth, which affect sound quality and latency:

• SBC — basic codec, works on all devices, but with mediocre quality.
• AAC —better for music, but may cause delays during calls.
• aptX —high quality, but not supported by all headsets.
• LDAC —best quality for music, but not optimized for voice.

Recommended for calls use SBC or aptX (if the headset supports). To change the codec:

1. Open Settings → Connected devices → Bluetooth.
2. Click on the gear icon next to the headset name.
3. Select Audio codec and change to the appropriate one.

Enable noise reduction

Many headsets (for example, Sony WH-1000XM5 or Bose QuietComfort) have an active noise reduction (ANC), which improves the perception of the interlocutor’s voice in a noisy environment. To enable it:

• In the proprietary headset application (for example, Sony Headphones Connect) find the section Noise Cancellation.
• Select mode "For calls" or "Adaptive ANC".
• On some models (Galaxy Buds), noise reduction is turned on automatically when call.

Setting the equalizer for voice

If the voice of the interlocutor sounds too quiet or, conversely, loud, you can adjust the sound settings:

1. Open Settings → Sound → Equalizer (on some phones you need to install an equalizer application, for example, Wavelet).
2. Select a preset "Voice" or manually increase the frequencies 1-3 kHz (responsible for speech intelligibility).
3. Make sure that the mode is not activated in the headset settings "Bass boost" —it can drown out the voice.

7. confidentiality

Bluetooth connection, like any wireless technology, has vulnerabilities. Although the risk of conversation interception is minimal (modern headsets use encryption AES-128), it is worth following a few rules:

How to protect the connection

• 🔒 Turn off Bluetooth when do not use a headset - this will prevent unauthorized connection.
• 📱 Regularly check the list of paired devices and remove unknown ones:

  Settings → Connected devices → Bluetooth → Tap on the device → Delete

• 🔄 Update your headset firmware - manufacturers regularly release security patches.

What to do if the headset is connected to someone else's device

If you notice that your headset is connected to an unknown phone:

1. Immediately disconnect it from other people's devices (via the Bluetooth settings on your phone).
2. Reset headset settings to factory settings (usually by holding the power button for 10-15 seconds).
3. Enable the function "Only trusted devices" (if it is in the headset settings).

⚠️ Attention: Some headsets (for example, AirPods) automatically connect to devices on the iCloudnetwork if they were previously paired with iPhone. To avoid this, disable the "Automatic switching" function in the Bluetooth settings on iPhone (if you have it).

8. FAQ: Answers to frequently asked questions

Can AirPods be connected to Android and will they work normally for calls?

Yes, AirPods (including AirPods Pro 2 and AirPods Max) can be connected to Android manually via Bluetooth menu. However:

• Will not work automatic switching between devices and Spatial sound.
• The quality of the microphone may be worse than on iPhone, due to lack of optimization.
• To check the charge level, you will need a third-party application (for example, AirBattery).

To connect: turn on pairing mode on AirPods (hold the button on the back of the case), then find them in the Bluetooth menu on Android.

Why does the headset connect as a “media device”, but does not transmit voice during a call?

This happens if the profile is not activated HFP (for calls). Solutions:

1. In the Bluetooth settings, click on the name of the headset → enable the option "Use for calls".
2. During a call, click on the icon Audio and manually select the headset.
3. Restart your phone and headset.
4. If the problem persists, reset the Bluetooth settings on your phone:

   Settings → System → Reset → Reset Wi-Fi, mobile network and Bluetooth

How to reset Bluetooth settings on your phone if the headset does not connect?

Resetting Bluetooth settings deletes all saved devices and returns the settings to factory settings. Instructions:

1. Open Settings → System → Reset.
2. Select "Reset Wi-Fi, mobile network and Bluetooth settings".
3. Confirm the action (You may need to enter a PIN code or pattern).

After resetting, reconnect the headset.

Can one headset be used on two phones at the same time?

It depends on the headset model:

• 🔹 Multipoint support: Headsets with function multipoint (for example, Sony WH-1000XM4, JBL Live 660NC) can connect to two devices simultaneously. In this case, the call will be sent to the device that is actively in use.
• 🔹 Without multipoint: Most budget headsets (for example, Redmi Buds 3) can remember several devices, but connect to only one. To switch, you need to manually disconnect the headset from the first phone.

To check multipoint support, study the characteristics of your model on the manufacturer's website.

Why is noise or crackling heard in the headset during a call?

Interference can occur for several reasons:

• 📶 Weak Bluetooth signal: Make sure that there are no obstacles (walls, metal objects) between the phone and the headset. The maximum distance for stable communication is 10 meters.
• 🔋 Low charge of the headset: When the charge level is below 15%, distortion may appear.
• 🎛️ Inappropriate codec: Try changing the Bluetooth codec to SBC (in the headset settings).
• 📱 Conflict with other devices: Disable other Bluetooth devices (for example, a smart watch or speaker).

If interference remains, try connecting the headset to another phone - if the problem persists, the Bluetooth module in the headphones may be faulty.
