The ESM3 is a great choice for an economical headset. The ESM3's super lightweight design makes wearing the microphone more comfortable, even for long periods of time, without using excessive pressure to hold the microphone in place. The soft microphone stem allows for easy adjustment of the microphone's position as you wear the headset. These headset microphones work great with many wireless transmitters available. The ESM3 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 ESM3 microphone with most PC sound cards (adaptor not included).
