Why do my Galaxy Buds3/Buds3 Pro make a screeching sound when I touch them?

Your Galaxy Buds3 or Buds3 Pro may produce screeching or howling noises when you touch or cover the sub-microphone, especially when Active Noise Cancellation (ANC), Adaptive Sound, or Ambient Sound modes are enabled. This occurs because the microphone detects unintended sound input, causing audio feedback.

1. Why does this issue happen?

Galaxy Buds3 and Buds3 Pro use external microphones to monitor surrounding noise for ANC, Adaptive Sound, and Ambient Sound modes. When you touch or cover the sub-microphone (located on the outer edge of the earbud), it picks up muffled or amplified sounds, leading to feedback loops that manifest as screeching or beeping noises.

- Active Noise Cancellation (ANC) relies on external microphones to analyze ambient noise and generate counter-frequencies.

- Adaptive Sound adjusts audio output based on real-time environmental analysis using these microphones.

- Ambient Sound mode uses the same microphones to let you hear surrounding sounds, making them more sensitive to physical contact.

2. How to prevent screeching sounds

  1. Ensure the sub-microphone area remains uncovered when handling your earbuds.
  2. Avoid pressing or covering the outer edge of the earbuds while wearing or adjusting them.
  3. Turn off ANC, Adaptive Sound, or Ambient Sound temporarily if the issue persists during handling.
  4. Check for debris or moisture near the microphone that could interfere with sound detection.

3. Additional things to check

- Update your Galaxy Buds3/Buds3 Pro firmware via the Samsung Wearable app to ensure optimal microphone functionality.

- Clean the earbuds gently with a soft, dry cloth to remove dust or residue around the microphone area.

- Test the earbuds in different environments to rule out interference from loud background noises.
