The Ulanzi AM18 U-Mic 2-Person wireless microphone system features two clip-on transmitters with built-in omnidirectional microphones and a dual-channel receiver with 3.5mm TRS and USB-C connectivity. You can attach the transmitters to your lapel and record your next vlog or two-person interview. Both components can communicate from a distance of up to 100 m via a 2.4 GHz frequency.
