The Microphone is very small with its High-Gain. It is also extremely sensitive and will be able to pick-up even the slightest of whispers. The Microphone can be placed on a wrist or under a collar. To attach it, tape the Microphone firmly around your wrist or under your collar but avoid taping over the top cap of the Microphone, as this will cover it up and reduce its performance.
Avoid the Microphone rubbing against clothing when you move, as this will cause unwanted noise to the person listening to you. Wear light clothing for best voice detection and do not place mobile phone, or any similar RF devices too close to the Microphone, as it can cause buzzing or interference.
