Wired handheld microphones connect to audio equipment through a cable, which simplifies system design and frequency planning but limits mobility and requires cable routing. Wireless handheld microphones use a transmitter and receiver to support movement around a room or stage, while installation must account for receiver placement, channel or frequency setup, power, and RF coverage.

A cardioid pickup pattern is well suited for reducing feedback and isolating a speaker’s voice because it focuses on sound from the front while reducing pickup from the sides and rear. This pattern works well for handheld microphones used in presentations, training rooms, houses of worship, and live performances.

Check that the microphone’s output type and connector match the available input on your mixer or amplifier, such as a balanced XLR input, and confirm whether a condenser microphone requires phantom power. For a wireless handheld microphone, verify that the transmitter and receiver use the same wireless system, frequency band, and compatible channel or pairing method, then confirm that the receiver’s output matches the audio input.

Look for a handheld microphone with a cardioid pickup pattern, smooth vocal reproduction, and a grille designed to reduce plosives and sibilance. An internal shock mount or anti-shock design can help reduce handling noise, while wireless models with true diversity reception, frequency scanning, or selectable power settings support reliable operation.
