The Sennheiser EW-D ME3 SET is a digital UHF wireless headset microphone system featuring the ME 3 cardioid headset mic, delivering pristine 24-bit audio, ultra-low latency and fast Bluetooth setup—ideal for presenters, performers, educators and houses of worship.

The Sennheiser EW-D ME3 SET (R4-9) combines legendary Sennheiser sound quality with modern digital wireless technology in a system that is both powerful and easy to use. Operating in the UHF band (552–607 MHz), this system delivers reliable performance, extended range up to 100 m (330 ft), and exceptional audio clarity thanks to 24-bit digital transmission and an ultra-wide 134 dB dynamic range.

Designed for hands-free speech and presentation, the included ME 3 cardioid headset microphone offers focused vocal pickup with reduced background noise and feedback. The lightweight EW-D SK bodypack transmitter pairs effortlessly with the half-rack EW-D EM receiver using Bluetooth Low Energy, allowing fast setup and control directly from your phone via the Smart Assist App.

With an equidistant tuning grid across 2240 frequencies and support for up to 90 simultaneous channels, the EW-D system eliminates complex frequency coordination—even in congested RF environments. Intelligent Switching Diversity ensures stable RF performance, while the ultra-low 1.9 ms latency makes it equally suitable for live performance and spoken-word applications. Built for professionals but simple enough for first-time users, the EW-D ME3 SET is a future-ready wireless solution for modern production environments.
