Sennheiser EW-D ME3 Wireless Headset System

The Sennheiser 508711 is a wireless headset system created for people who move while they speak. Presenters, educators, fitness instructors, and stage performers can walk, turn, or demonstrate without worrying about a microphone cable, yet still deliver voice that stays clear and consistent.

The system centers on a sturdy bodypack transmitter that clips to a belt or pocket. It pairs with the discreet ME 3 headset microphone, which uses a cardioid pattern to focus on the wearer’s voice and reduce surrounding noise. This makes spoken words easy to understand in classrooms, conference rooms, and live venues.

Setup is straightforward. Open the EW-D Smart Assist App on a phone, touch to pair, and the receiver locks onto a clean frequency. From there, you can adjust levels, mute the mic, or check remaining battery life without stepping backstage.

Operating between 520 MHz and 576 MHz, the system avoids most common sources of interference in event spaces. A 20 Hz to 20 kHz audio response captures the full spectrum of speech and subtle vocal inflections, so every presentation or performance sounds natural.

The included AA batteries run up to 12 hours, long enough for day-long conferences or multiple fitness classes. Both the transmitter and the rack-mountable receiver use metal housings that hold up to daily travel and repeated setup.

Everything needed to get on the air arrives in the box: the receiver, bodypack transmitter, ME 3 headset mic, batteries, mounting hardware, and cables. Power it up, pair through the app, and you are ready to deliver professional audio in minutes.
