Recorded voice / interview on my end gives a reverberating or resounding effect.

Can can anyone help me with my echoing / resounding / reverberating sound issues? 

I have already tried everything in the audio settings , for example by changing the setting of echo reduction to high. 

There a bunch of other windows specific audio settings in zoom, which I do not understand. 

I am using a pretty professional USB-mic by Marantz via Desktop. 

Any help appreciated. 

Thanks.
