I WAS joking, but normally I don't use monitors on one-night jobs. I set up between the speakers and angle the left one toward the right and right one toward the left (reminds me of a Kingston Trio song).
I like hearing the mains if I don't have to be too loud. Also use the onboard speakers to monitor sometimes.
When I had X1 and G800 I did use the earbud types sometimes. They worked fine, but I'm certain they don't sound as good as the high-priced ones.
