These single-ear headset microphones work great with many wireless transmitters, like Galaxy Audio's wireless microphone body packs. The Audio-Technica Gen 2 cH detachable cables can be wired to work with transmitters made by Galaxy Audio, Shure, Sennheiser, AKG, and Audio-Technica, as well as most other brands of wireless microphone systems. You can also use the Galaxy Audio ESM4 single-ear headset microphone with most PC sound cards (adapter not included).
