  2. Explore these options:
    • Pause amplification: Tap Pause Pause.
    • Change the sound settings: On the Sound tab, try changing the Boost and Fine tuning controls to find the setup that works best for you. 
    • Adjust ears separately: On the Sound tab, turn on Adjust ears separately to apply settings to the right and left audio independently. For Bluetooth headphones, this setting only applies to on-device audio, not to sound from your surroundings.
    • Reduce unwanted sounds: On the Noise tab, change the noise reduction level.

Troubleshoot issues with Bluetooth headphones

With Bluetooth headphones, sound might be delayed or lower quality. To improve the sound quality and reduce the delay, try these steps:

  1. In Sound Amplifier, go to the Source tab. In the Microphone menu, select Device mic.  
  2. Bring your headphones closer to your phone, and avoid placing objects between the headphones and your phone.  

Some brands of Bluetooth headphones might have lower quality audio and latency. If the steps above don't improve your sound quality, try switching to wired headphones.
