Unfortunately since it’s an active feature it requires power, meaning any wired headset will require a battery or other power source.

A wired headset plus my mixer gives me an opportunity to tinker and upgrade my setup as I wish, and is all USB powered to boot.

I have some rough plans to make a simple audio interface with built in sidetone for use as a portable setup, but haven’t had the time to turn it into a real product. Someday!
