Echo in calling with liberty 3 pro

People on the other side of the call says that there is echo of my voice. Do you guys experience it? How to fix the issue?

How good is the seal?

Is it in normal mode? (Not ANC nor ambient)

I don’t personally experienced this using my L3P’s during calls, but I also don’t use them a lot for calls. I have tested them though and the feedback I received was that they sounded as good as if I was just using my phone.

Seal is good. It’s in normal mode. The echo is very minimal though. But I think it is not normal to have echo.
