The Shared DNA: Innovation Without Compromise
Before we dive into the specific tiers, it’s important to acknowledge what stays the same. We respect our users' need for quality at every level, which is why all systems in this family feature:
- Pristine Digital Audio: Lossless quality that brings the legendary Sennheiser sound into modern live workflows.
- The 134 dB Dynamic Range: We’ve effectively "blown past" the limitations of the past. You no longer need to worry about transmitter sensitivity; if the mic can hear it, the system can handle it.
- Bluetooth® Low Energy Sync: We've replaced finicky infrared with reliable Bluetooth pairing. It’s the modern "handshake" your setup deserves.
- Total Cross-Compatibility: We build systems to grow with you. Transmitters and receivers across the D, DX, and DP lines are interchangeable.
1. EW-D: The Surprisingly Approachable Workhorse
The EW-D is for the artist who values a minimalist approach without sacrificing a shred of quality. It’s our way of making professional digital wireless accessible to everyone.
- Who it’s for: Solo musicians, singer-songwriters, and small bands who need to get up and running in seconds.
- The Workflow: Controlled entirely via the Smart Assist App. We’ve moved the complexity into the app so you can focus on the stage.
- The Engineering: A single-channel receiver (EM) that fits perfectly into any standard rack. It’s the easiest system we’ve ever made to use.
2. EW-DX: Respectfully Self-Confident Scalability
When your environment grows, your system needs to grow with it. EW-DX is designed for the professional who needs maximum flexibility and the "X" factor in better scalability.
- Who it’s for: Touring acts, large-scale theaters, and campus-wide installations.
- The Power of Choice: From dual-channel receivers (EM 2) to the massive four-channel EM 4 Dante, we give you the tools to fill an entire rack unit efficiently.
- Network Integration: This is where our passion for tech shines. EW-DX is fully network-compatible, working seamlessly with Sennheiser Control Cockpit and Wireless Systems Manager (WSM).
- Professional Extras: Unique hardware like the TS Table Stand for goosenecks and the ability to charge your transmitters without ever removing the BA 70 batteries.
3. EW-DP: Portable Precision for Filmmakers
The "P" stands for Portable, but it also stands for "Problem-solved." We’ve shrunk our best tech into a miniature form factor designed for the rigors of production.
- Who it’s for: Content creators and filmmakers who need the Sennheiser sound on the move.
- Innovation in the Palm of Your Hand: The SKP Plug-on Transmitter is a standout. It turns any XLR mic into a wireless one and features an on-board Micro SD card recorder—because we know how much a backup matters when there are no re-takes.
- Smart Design: A tiny, stackable receiver that stays out of your way while you’re behind the lens.

The Mix and Match Philosophy
We don’t believe in locking you into a single path. Artists trust Sennheiser because our systems are modular and honest. You can use an EW-DX transmitter with your EW-D receiver today and upgrade your rack tomorrow. The system adapts to your needs, not the other way around.
Which Path Will You Take?
- Choose EW-D for the purest, simplest connection between your voice and your audience.
- Choose EW-DX when the network is your stage and you need the confidence of Dante and WSM control.
- Choose EW-DP when you’re telling stories on the move and every gram of weight counts.

Evolution Wireless Digital: Frequently Asked Questions
Q: How many Sennheiser EW-D units can you use simultaneously?
A: Thanks to our equidistant frequency grid, you can operate up to 90 channels of EW-D or EW-DX in the same environment. This eliminates the need for manual frequency coordination and ensures intermodulation-free performance even in crowded RF spaces.
Q: What is the main difference between Sennheiser EW-D and EW-DX?
A: While both offer identical 1.9ms latency and sound quality, the EW-DX is built for scale. It features dual-channel receivers, network-based control (WSM/Control Cockpit), and optional Dante integration, whereas EW-D is a single-channel system managed primarily via Bluetooth and the Smart Assist App.
Q: Does the Sennheiser EW-D system require a frequency chart for setup?
A: No. We’ve moved past traditional frequency charts. The EW-D utilizes a Fixed Frequency Grid where channels are placed at equal distances from one another. This "equidistant grid" prevents intermodulation automatically, allowing you to simply pick a slot and perform.
Q: Is there an IEM (In-Ear Monitor) version of the Evolution Wireless Digital?
A: Currently, the Evolution Wireless Digital family is focused on microphone transmission. However, Sennheiser does offer XSW IEM Set which has all the components you need to set up your personal monitoring in minutes.
Q: Can I use EW-D for wireless guitar?
A: Absolutely. With the CI 1 instrument cable, the EW-D provides a wide frequency response and 134 dB dynamic range that captures the full character of your guitar or bass without the "squashed" sound often associated with analog wireless compressors.
Q: What app do I use to control my Sennheiser EW-D system?
A: Use the Sennheiser Smart Assist App. It allows you to monitor battery life, name your channels, and perform automated setup for up to 16 channels directly from your mobile device via Bluetooth Low Energy.
Q: Does the EW-DP SKP plug-on transmitter provide phantom power?
A: Yes. The EW-DP SKP transmitter provides +48V phantom power, allowing you to turn any professional condenser microphone into a wireless digital tool. It also features a built-in MicroSD card recorder for an added layer of security.
Q: What is the battery life of the BA 70 rechargeable pack in these systems?
A: The BA 70 rechargeable lithium-ion battery provides up to 12 hours of operation. If you’re caught without a charge, the transmitters also support standard AA batteries, offering roughly 8 hours of runtime.
Q: Can I use an EW-DX transmitter with an EW-D receiver?
A: Yes. All transmitters in the Evolution Wireless Digital family are cross-compatible with the receivers. You can mix and match D, DX, and DP components to suit your evolving needs.
Q: How does EW-D handle interference compared to older analog systems?
A: Digital wireless is inherently more robust, but EW-D goes further with its equidistant frequency grid. By spacing channels intelligently, it avoids the "math problems" that cause interference in analog systems, even in cities with heavy TV station traffic.
