Sometimes it May Be Audio Problem That Feels Like Not Connecting:

Volume Settings for Each Earbud:

Some devices offer individual volume settings for each earbud. Depending on your preferences, you can mute or decrease the volume of a specific earbud. If one earbud is not producing sound, adjust the volume accordingly.

Fixing Audio Imbalance:

  • Navigate to your device’s audio settings.
  • Access the accessibility menu to find options for adjusting audio balance.
  • Modify the volume levels between the right and left earbuds to restore sound balance.
  • If supported, utilize a companion smartphone app for fine-tuning audio balance.

Stereo/Mono Audio Settings:

Despite Bluetooth earbuds being sold in pairs, they can be used individually. Modern models automatically detect the number of earbuds in use and switch between stereo and mono sound modes.

Some devices offer manual switching between stereo and mono modes.

To enable sound on both earbuds:

  • Access your device’s audio settings.
  • Choose the Accessibility option.
  • Tap on Sound Balance.
  • Toggle the switch next to mono to disable it or select stereo mode.
