Earworn microphone, cardioid, black • Cardioid polar pattern • Lightweight, flexible ear loop • Suitable for spectacle wearers • Unobtrusive design in black or beige • Suitable for use with beltpack transmitters • Supplied with pop shield The PEM 10 has been designed for "hands free" applications with wireless systems and is ideal for sales and product seminars, workshops, entertainers, dancers, drummers, keyboard players etc. It is also suitable for musicals and theatre use or for guided tours through museums, galleries or factories when using a wireless system. Featuring a small yet rugged ear loop, the PEM 10 is also suitable for spectacle wearers. Due to its cardioid polar pattern the PEM 10 features a high gain before feedback and eliminates rear sound.
