Description

The Sennheiser SL Handheld DW-4-US is a professional wireless handheld microphone system built for high-stakes speech applications such as corporate presentations, lectures, and panel discussions. It delivers exceptional clarity through a true condenser microphone capsule (MME 865) with a supercardioid pickup pattern, offering excellent rejection of ambient noise and feedback for focused voice capture.

Operating in the 1920–1930 MHz frequency range, this mic system includes automatic frequency and interference management for a seamless, reliable wireless experience. With bidirectional communication, all settings can be controlled remotely through the receiver, removing the need for on-device adjustments. The onboard LC display provides real-time data such as battery status, signal strength, and pairing info, while a convenient mute slider ensures quick access during live presentations.
