General
The lightweight Shure WH20 is a headset microphone that delivers high-quality vocal reproduction. This microphone is adjustable to virtually anyone's head, and is great for people who want freedom of movement while using their voice, like fitness instructors, musicians and presenters, for example, who often need both hands to play an instrument or demonstrate exercises. The headband is fully adjustable for a universal fit; additionally, it comes with a windshield and a clip to attach the mic to your clothing.
Cardioid pickup pattern
The WH20's microphone has a cardioid pickup character, which means ambient noises made by air-conditioning, instruments and speakers won't be picked up, and feedback is kept to a minimum. A specially-adapted frequency range has a low-frequency roll-off which compensates for the proximity effect, which can happen when singing directly into the microphone, causing a change in the frequency response and therefore emphasising lower frequencies. You'll be getting top-quality sound, in any situation!
