Andrea NC-185 VM USB listening to some audio or video . It seems that my microphone is listening to the output sound in my headphones

Hi , I bought andrea NC-185 VM USB, it really is a good headset to dictate to Dragon, almost 100% accurate

But theres an issue:

When I’m listening to some audio or video . It seems that my microphone is listening to the output sound in my headphones.

I use Dragon NaturallySpeaking and voicecomputer, when playing commands or speaking with Dragon, if I play a music on the headphones it ruins my work

How can I solve this issue?
