Overview

The Samson R21S is a handheld dynamic microphone built for vocalists, presenters, and performers who need reliable sound capture without a complicated setup. Its cardioid polar pattern focuses pickup on the sound source directly in front of the microphone while attenuating noise from the sides and rear — a critical feature for live stages, rehearsal spaces, and presentation halls where ambient sound can be a problem. The shock-mounted element inside the capsule adds another layer of noise reduction by dampening the vibrations that come from handling the mic or moving it on a stand.

Practical design choices make the R21S easy to work with in real-world settings. The integrated on/off switch lets performers mute quickly between songs or during breaks without relying on a mixing board. The low-impedance, high-gain output ensures the signal reaching your mixer or PA system is strong and clean, reducing the need to crank preamp levels. With no phantom power required and a standard XLR connection, the R21S plugs into virtually any audio setup. Its 80Hz to 12kHz frequency response is shaped for vocal clarity, rolling off the low-end rumble and focusing on the midrange frequencies where speech and singing live.
