Perfect for Vocals and Speech!
Versatile digital wireless system for singers, speakers, and instrumentalists. It offers seamless pairing and clear management of all products via the EW-D Smart Assist app.
The proven Sennheiser capsule e 835 on the lightweight handheld transmitter with integrated mute switch delivers live sound with the latest technology.
Setting New Standards
Evolution Wireless Digital breaks current limits with a wider dynamic range than any other system currently available. In daily use, the system automatically finds the best transmission frequency within seconds and simultaneously allows up to 90 additional channels thanks to the 56 MHz switching bandwidth. It’s easy to see: this wireless system is in a class of its own.
Equidistant Spacing – Easier Than It Sounds
Evolution Wireless Digital features an equidistant frequency grid, previously only found in Sennheiser’s flagship systems like Digital 6000 and Digital 9000. High-quality components with exceptional linearity eliminate intermodulation between EW-D transmitters, allowing frequency allocation every 600 kHz side by side. This simplifies coordination for both beginners and pros alike. Additionally, it contributes to the system’s scalability and high channel limit.
The Sound Engineer in Your Pocket
With the Sennheiser Smart Assist app and the power of Bluetooth Low Energy, control literally lies in your hand. Conveniently from your Android or iOS device, enjoy the benefits of fast automatic setup, mobile access to all system settings, and remote monitoring.
Saves Time and Energy, Enabling Stress-Free Work!

Questions about product
Question by Zack on 24.07.2022
Hi Sir/Madam,
This U1/5 frequency band looks much narrower than other available bands like R1-6, so there won’t be as many channels. Will the chance of locating an available frequency be lower?
Thanks a lot!!
