Rigorously engineered to meet the needs of demanding professionals working in business and educational settings, houses of worship, or on stage, the Sennheiser EW-DX 835-S SET is a dual-channel digital UHF wireless system with an impressive feature set designed to simplify your workflow while delivering uncompromising audio quality. This configuration includes a dual-channel, 1/2-rack receiver and two handheld transmitter/mics with mute switch and MMD 835 cardioid capsules.
With a remarkable 134 dB dynamic range on the transmitters, the mics can handle just about any input level you throw at them. The wide 80 MHz tuning range, intelligent switching diversity, auto-scan, equidistant tuning grid, and Link Density mode work to provide rock-solid wireless performance and massive channel counts, even in challenging RF environments. Bluetooth capabilities allow you to remotely sync components and change settings from your phone using the Smart Assist app, while Sennheiser's Control Cockpit and Wireless Systems Manager software provide computer-based control for more extensive networked setups. The EW-DX is backward-compatible with EW-D components.
Rock-Solid Wireless Audio with Professional Digital Sound & More Mic Channels
- The UHF transmission greatly enhances range (up to 330') and the wide 80 MHz bandwidth gives you the ability to find a clean channel from 3200 available frequencies.
- Intelligent Switching Diversity compares incoming signals on two independent antennas and receiver circuits to ensure optimal wireless quality. The receiver switches between antennas only during header data as to never affect the audio information.
- The equidistant tuning grid removes the need for frequency coordination and allows you to add additional transmitters and receivers for up to 134 mic channels simultaneously.
- For complex systems requiring even more mics, engage the Link Density mode for up to 269 channels on the same system.
2 Handheld Transmitters with Mute Switches, MMD 835 Capsules, and e-Ink Displays
- The two rugged, all-metal handheld transmitters are equipped with lockable mute buttons along with function buttons that allow you to control all the transmitters' settings directly from the mic.
- The MMD 835 dynamic capsules feature a cardioid polar pattern that helps minimize background noise and feedback.
- The e-Ink display helps you quickly name and identify the transmitter and allows you to see parameters, even when the unit is powered off.
- Each transmitter will operate on its included BA70 rechargeable battery for up to 12 hours. Two AA batteries will power the transmitter for up to 8 hours. Charging contacts allow for in-device battery charging with the CHG 70N (available separately).
- The interchangeable capsule design allows you to use a variety of optional dynamic and condenser mic capsules, with pickup patterns ranging from wide omnidirectional to narrow supercardioid—capsules include the MMD 845, MME 865, MMD 935, MMD 945, MMD 42, MM 435, ME 9004, MD 5235, ME 5004, and Neumann KK204 to name a few.
- Input trim controls allow you to adapt individual transmitters for group performances.
Add Functionality with Additional Transmitters, Mics, and Accessories
In addition to the handheld transmitter/mics included with this system, Sennheiser offers a number of separately additional transmitter and mic options for the EW-DX system as your needs evolve.
- The EW-DX SK bodypack transmitter is available with either a locking 3.5mm input or a 3-pin LEMO connector to accommodate a lavalier mic, headset mic, or guitar cable.
- For conferences and meetings, the EW-DX TS is a tabletop transmitter that provides a stable base for gooseneck microphones and is available with 3-pin or 5-pin XLR inputs.
To maximize the reliability of the system, consider upgrading the included antennas.
- The rear-mounted, 1/4-wave detachable antennas can be upgraded to longer, 1/2-wave dipole antennas (available separately) for added range and reliability; users can also choose an ADA UHF Active Antenna or the AWM Wallmount Antenna as well.
- For setups with multiple receivers, the EW-D ASA Splitter allows you to split and distribute a dual-antenna signal across 4 receivers for clearer reception without the intermodulation problems that can occur when multiple antennas are used.
Dual-Channel Receiver with OLED Screen & Bluetooth
- The all-metal, 1/2-rack, dual-channel EW-DX EM 2 receiver offers intuitive front-panel controls and a high-contrast OLED with meters for RF, battery status of the associated transmitter, and audio output that make setup a breeze.
- Bluetooth capabilities allow you easily sync transmitters at a distance of up to 120' away and control the receiver remotely from your smartphone using the Smart Assist app.
- The RJ45 port allows for PoE (Power over Ethernet) as well as networked control via Sennheiser's Wireless Systems Manager and Cockpit Control software.
- Balanced XLR outputs as well as unbalanced 1/4" outputs provide plenty of connection options for PA systems and recording equipment. A front headphone jack with volume control is also provided, along with an external PSU if you're not using PoE.
- A rackmounting kit is included.

When in a pinch, even Monaco couldn’t tell the difference.
Size: XX-Large, Color: Navy
Here’s the revised review with the updated final paragraph:
---
**When in a pinch, even Monaco couldn’t tell the difference**
There I was, stranded in the Swiss Alps, of all places, when an urgent call came through—a last-minute invite to a charity gala in Monaco. You can imagine my predicament. No tuxedo, no time to fly back to Dutchess County to retrieve the one I had custom-tailored in Sardinia by Fabrizio, the island’s finest (and only) tailor. Fabrizio’s tuxedo, you see, wasn’t just any suit. I had it made after a rather *unique* incident involving a chess tournament, a peculiar art heist, and the world’s finest pecorino cheese. But I digress.
With no time to return to Dutchess County—or even Sardinia—there I was, frantically searching for something that wouldn’t make me look like an underdressed disaster among the crème de la crème. Amazon to the rescue. I stumbled upon this navy blue tuxedo with a black shawl collar and, in a state of mild desperation, ordered it around midnight.
It arrived before I even woke up the next morning. Amazon’s overnight delivery, an absolute lifesaver. I put it on, and, to my surprise, the fit was near perfection—almost as if Fabrizio himself had secretly slipped his measurements to the manufacturer. The deep navy color was striking, and the black shawl collar gave just the right amount of contrast. It looked like a tuxedo far more expensive than the one I’d ordered in a slight state of panic.
At the event, the tuxedo didn’t just blend in—it stood out. More than a few people took notice, including a former diplomat who, with raised eyebrows, asked if I’d had it custom-made in Milan. I simply smiled and let the mystery linger. The tux held its own through hours of mingling, dancing, and even a few strategic maneuvers to avoid the advances of a rather persistent heiress. And by the end of the night? Not a wrinkle to be found.
Now, about the fit—be warned. It's tight. Very tight. If you decide to give this tux a try, order two or even three sizes up. And unless you have time to see a tailor, the trousers will almost certainly need hemming. In a real pinch, fabric tape will do the trick. But once you’ve got the sizing sorted, it’s all smooth sailing from there.

Tricky Fit
Size: 3X-Large, Color: Black
First order returned - pants fit, jacket & vest too small. Reordered a size up - pants too big, jacket & vest fit. The pants had to be hem and waistband taken in. And still need suspenders. My advice, give yourself enough time for alterations.

Good quality
Size: 3X-Large, Color: Black
Loved the quality for the price. Fit is more for a size under what is listed. The pants are hip huggers not waist high.
