4. Close the case, wait 30 seconds and reconnect.

If after rebooting the right earphone works, the problem was in firmware conflict. If not, proceed to check the connection.

3. Connection problems: Bluetooth and compatibility One of the most common reasons why is a malfunction of the smartphone or protocol incompatibility. For example, headphones

One of the most common reasons why the right earphone does not connect to - malfunctions Bluetooth module smartphone or protocol incompatibility. For example, headphones Samsung Galaxy Buds may conflict with smartphones running MediaTek, and AirPods via an adapter - with devices running older versions of Android.

What to check:

• 📱 Bluetooth version on a smartphone (must be at least 4.2 for most TWS headphones). You can view it in Settings → About phone → Bluetooth version.
• 🔄 Connection mode — some headphones require connecting the left one first and then the right one (for example, JBL Tune 125TWS).
• 🚫 Conflict with other devices — turn off all other Bluetooth gadgets (fitness bracelets, smart watches).

Headphone model	Minimum Bluetooth version	Typical problems
Xiaomi AirDots	4.2	The right earphone turns off when the case's charge is low
Samsung Galaxy Buds+	5.0	Conflict with Android firmware 10 and lower
JBL Free X	4.1	Problems with sound balance after updating the firmware
Apple AirPods (via adapter)	4.0	Audio delays and turning off the right earphone

1. Press and hold the touchpad on the RIGHT earphone for 7 seconds.
2. Repeat for the LEFT earphone.
3. Reconnect them.

After resetting, the headphones may require a firmware update. Check for updates in the official brand application (for example, for Samsung or for Xiaomi). Resetting the settings helps in 60% of cases when the right earphone does not work due to a software glitch. If the problem remains after the reset, the reason is most likely hardware. Galaxy Wearable for Samsung or Mi Home for Xiaomi).

6. Software conflicts: firmware, applications, viruses

Sometimes the right earphone stops working due to conflicts in the Android firmware or third-party applications. For example:

• 🤖 Android update bluetooth settings (relevant for smartphones on Android 12+).
• 🎵 Players with custom sound settings (for example, Poweramp or ViPER4Android) can block one of the channels.
• 🦠 Viruses or optimizers (type Clean Master) close background Bluetooth processes.

What to do:

1. Start your smartphone in safe mode (hold the power off button → "Safe Mode"). If the headphones work fine in it, the problem is in one of the installed applications.
2. Uninstall recently installed apps, especially those that requested access to Bluetooth or Microphone.
3. Update the headphone firmware through the official brand application.

If a conflict occurs after updating Android, try roll back to the previous version (if possible) or wait for a patch from the manufacturer. On forums they often post custom firmware for headphones that solve compatibility problems.

7. Hardware faults: when you need specialist help

If all software methods have been tried, but the right earphone still does not work, the reason is most likely Hardware. Here are the most common breakdowns:

Symptom	Probable cause	Repair cost (≈)
