How to Fix Microphone Echo on Windows & Mac

Microphone echo makes calls difficult. Here is how to eliminate it.

Why Echo Happens

Echo occurs when your microphone picks up sound from your speakers, which is then transmitted back to callers — who hear their own voice with a short delay.

Fix 1: Use Headphones

The single most effective fix. When audio goes directly to your ears, the microphone cannot pick it up.

Fix 2: Reduce Speaker Volume

Lower volume = less acoustic feedback into the microphone.

Fix 3: Enable Noise Cancellation

Windows:

• Right-click speaker → Sound → Recording → your mic → Properties → Enhancements
• Check Acoustic Echo Cancellation

Zoom: Settings → Audio → Suppress Background Noise → High

Teams: Settings → Devices → Noise suppression → High

Meet: Settings → Audio → Noise cancellation → ON

Fix 4: Disable Microphone Monitoring

1. Right-click speaker → Sound → Recording → your mic → Properties
2. Click Listen tab
3. Uncheck Listen to this device

Fix 5: Increase Microphone-to-Mouth Distance

Moving the mic closer to your mouth (and further from speakers) reduces feedback pickup.

Fix 6: Disable the Built-in Microphone

If you have both a USB mic and a built-in mic active, disable the built-in one in Device Manager.
