HDi Acoustic Presenter and Audience Microphones
The HDi Acoustic Presenter Microphone is small enough to fit in a shirt pocket and lightweight enough to be comfortably worn on the included lanyard.
It also includes Page-up/Page-down buttons on the side to make it easier for a presenter to roam the presentation without needing to carry along a “clicker.”
And The HDi Acoustic Audience Microphone fits comfortably on a hand and has a non-slip coating on the sides and back.
