About Headworn Microphones at Sound Productions

Small but mighty, headworn microphones are designed specifically for versatility, portability, and for delivering accurate sound without distracting your audience.

Versatility is a cornerstone of every headworn microphone, making the possible applications limitless. They’re ideal for public speaking environments including lecture halls, classrooms, business conferences, live broadcasts, and houses of worship. Singers and actors can enjoy freedom of movement on the stage. Instructors in active environments (think fitness trainers or presenters at how-to seminars) can clearly convey information while keeping their hands free for demonstrations. Because most headworn mics are designed with the mics placed at the end of repositionable cables, you can adjust the mic placement to exactly capture the sound you want.
