A Vibromic
Vibromic is the nickname given to the pea-sized microphones often used in live events such as orchestral performances and music gigs. Due to their small size, the biggest problems during performances is both countering their hypersensitivity and removing the 'tinny' sound they often produce.
They are usually covered in pop shields, which can include larger handles and signal boosters, though most of the harmonic boosting can be covered with external technology.
