An echo sound is heard when wearing the LinkBuds Fit earbuds

When using the earbuds' Noise Canceling function or Ambient Sound mode, an echo sound may be heard in the following situations. This is normal and not a malfunction.

• When you touch the earbuds' microphone (A) or bring your finger close to it
  
• When you cover your ear with your hand over the earbuds
  
• 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 do not cover the earbuds with your hands or other objects. This can help reduce the echo sound.
