How do they ensure that during a remote TV interview you can’t hear the interviewer speak through the speakers of the interviewed one?

Question

Even when they talk over each other, we still only hear the interviewer and the guest talk. We don’t hear the speakers. (As argument against noise cancelling)

I know they could wear something like airpods, but I didn’t see anything in their ears so how is it possible without?

For example look up the Piers Morgan interview with Kanye West, thats an example of what I’m curious about.

oh man that is wild how it works. they use fancy tech to split the audio signals so only the mic picks up right stuff. its like magic or somthing. and yeah no earpods makes it cooler to watch. i bet they got some secret convo going on tho when they cut to ads or smth.
