Focus less on the wireless and more on the audio. Sennheiser EW-DX simplifies your professional workflow by utilizing refined technologies and decades of research to deliver a digital UHF system that can be scaled with ease. Multiple hardware and software options create networkable solutions for nearly any stage, while equidistant channel spacing, auto scan, and Bluetooth® Low Energy sync automatically coordinate and set frequencies with the push of a button. Monitor your devices from a distance—even from your pocket—with tools like Wireless Systems Manager and Smart Assist app. The future of wireless is here.

Truly simplified workflow

EW-DX takes the complexities out of wireless audio by employing sophisticated tools that streamline the setup and monitoring process. With the press of a button, Auto Scan automatically assigns channels using an equidistant tuning grid that allows you to pack more channels more reliably, without problematic intermodulation interference. Take control of the system from your mobile device via the Sennheiser Smart Assist app or utilize advanced software options like Wireless Systems Manager (WSM) for a detailed system view in complex, networked environments.
