Sennheiser Ew-D Me3 Set (470,2 - 526 Mhz)

Evolution Wireless Digital: the "Evolution" spirit in a digital version

With Evolution Wireless Digital, Sennheiser advances its "Evolution" range approach toward a modular digital platform designed to meet modern RF constraints: rapid deployment, stability, and more intuitive management. This series incorporates principles previously reserved for the brand's high-end digital solutions (notably the use of a constant-interval tuning grid) to reduce coordination complexity and make installation more accessible, even when multiple systems are used simultaneously.

Who is it for and what are the use cases?

The Sennheiser EW-D ME3 SET is designed for artists and presenters who need a reliable and comfortable wireless headset microphone: singers, sports coaches, dance instructors, speakers, hosts, places of worship, corporate events, or stage performances. The headset microphone frees the hands and ensures constant vocal presence while offering a cardioid directivity useful for better controlling the sound environment (stage monitors, room sound reinforcement, ambient noise).

A system designed for reliability, speed, and control

Digital UHF transmission: clean sound and enhanced stability

The digital wireless technology of the EW-D series aims to eliminate typical artifacts (residual noise, interference) and maintain a stable signal. The UHF transmission helps improve range, reliability, and system scalability, whether for a simple mono-channel setup or in contexts where multiple links must coexist.

Smart configuration and mobile control

Bluetooth Low Energy, combined with the Sennheiser Smart Assist app, provides a smoother workflow: automated configuration, remote control, and mobile access to settings without navigating complex menus. A real time saver during soundchecks, tours, or quick-install events.

Scalability and frequency management

Within the Q1-6 (470.2 - 526 MHz) range, the system offers a 56 MHz bandwidth allowing up to 90 channels. It is also possible to select up to 2,240 frequencies, with the capacity to support up to 24 wireless systems per frequency range. The constant-interval grid aims to reduce RF coordination constraints and limit intermodulation issues, enabling a more confident approach during multi-system deployments.

ME 3 headset microphone: stable voice, articulation, and control

The Sennheiser ME 3 is a cardioid condenser (electret) headset microphone designed for close vocal pickup. Its headset form factor maintains a constant distance to the mouth, which is practical for keeping a consistent level, improving intelligibility, and securing the performance when moving on stage.

Battery life suited to performances

The transmitter can operate with a lithium-ion battery offering up to 12 hours of runtime, or with AA batteries for up to 8 hours. This flexibility is useful on tour, at events, or in fixed installations, depending on your power habits and logistical constraints.
