An echo sound is heard when using the LinkBuds Fit earbuds

You may occasionally hear an echo sound when using the Noise-canceling function or Ambient sound mode of your earbuds. It is normal and doesn't indicate a malfunction. Below are specific situations where this echo may occur:

• Touching the microphone: When you touch the earbuds' microphone (A) or bring your finger close to it
  
• Covering your ear: When you place your hand over your ear while wearing the earbuds
  
• Adjusting in noisy environments: When you adjust the position of the earbuds in a noisy environment by pressing them firmly against your ears

Hint: When putting on or adjusting the position of the earbuds, hold them lightly to avoid touching the microphone and don't cover the earbuds with your hands or other objects. This can help reduce the echo sound.
