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 SK-SKM-S BASE 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 1/2-rack, dual-channel receiver, one bodypack transmitter without a lavalier, and one handheld transmitter without a mic capsule—so you can choose your preferred lav mic and mic capsule for the application.
With a remarkable 134 dB dynamic range, the transmitters can handle just about any input level you throw at them. The wide 87 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 87 MHz bandwidth gives you the ability to find a clean channel from 3480 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 enables you to operate up to 146 mic channels simultaneously.
- For complex systems requiring even more mics, engage the Link Density mode for up to 293 channels on the same system.
1 Handheld Transmitter without Mic Capsule
- This set provides two transmitters, the first is a handheld transmitter without a mic capsule, so you can choose your preferred capsule for the application.
- 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 835, 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.
- The rugged, all-metal transmitter is equipped with lockable mute buttons along with function buttons that allow you to control all the transmitter's settings directly from the unit.
1 Bodypack Transmitter without Microphone
- This set also provides an all-metal bodypack transmitter with function controls and a locking 3.5mm input jack to accommodate your choice of compatible lavalier mic, headset mic, or guitar cable.
- The e-Ink displays helps you quickly name and identify the transmitters and allow you to see parameters, even when the units are powered off.
- Each transmitter will operate on its included BA70 rechargeable battery for up to 12 hours. Two AA batteries will power a transmitter for up to 8 hours. Charging contacts allow for in-device battery charging with the CHG 70N (available separately).
- Input trim controls allow you to adapt individual transmitters for group performances.
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.
Add Functionality with Additional Transmitters, Mics, and Accessories
In addition to the bodypack and handheld transmitter/mic included with this system, Sennheiser offers a number of separately available transmitters and mic options for the EW-DX system as your needs evolve.
- The EW-DX SK bodypack transmitter is also available with a 3-pin LEMO connector.
- 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 four receivers for clearer reception without the intermodulation problems that can occur when multiple antennas are used.

The Only Charger You’ll Ever Need!
The Anker 735 Charger (GaNPrime 65W) is a total game-changer for anyone tired of carrying multiple "bricks" for their laptop, phone, and earbuds. It packs a massive amount of power into a surprisingly small, foldable design.
What I liked:
True All-in-One: With two USB-C ports and one USB-A port, it can fast-charge a MacBook Air, an iPhone, and AirPods all at the same time.
Intelligent Power Allocation: It uses PowerIQ 4.0 technology, which automatically detects the power needs of each connected device and adjusts the output in real-time for the fastest possible charge.
Ultra-Compact: Thanks to GaN (Gallium Nitride) technology, it is about 53% smaller than a standard 67W laptop charger. The foldable plug makes it perfect for tossing into a travel bag or pocket.
ActiveShield 2.0: I really appreciate the peace of mind that comes with its advanced temperature monitoring, which checks the heat over 3 million times a day to protect your expensive devices.
Note: To get the full 65W speed for your laptop, make sure you are using a high-quality USB-C cable rated for 100W!
Whether you’re working from a coffee shop or traveling internationally, this is the most reliable and efficient charging block on the market. It’s a bit of an investment, but the build quality and convenience are worth every cent.

The 65W version is just as solid as the 47W I already own
I bought the 47W Anker Nano charger a while back and loved it, so when I needed a bit more power I grabbed this 65W version. Honestly, the experience is almost identical - which is exactly what I was hoping for. Same compact puck design, same foldable prongs that make it perfect for travel, same Anker reliability.
I've been using it with my Samsung Z Flip 7 and it charges incredibly fast on fast charge mode. The phone recognizes it immediately and you can watch the percentage climb. But what I really appreciate about stepping up to the 65W model is the extra headroom. When I need to charge my laptop or other more demanding devices, this charger handles them without breaking a sweat. The 47W is great for phones and smaller tablets, but having that extra wattage gives me more flexibility.
The folding prongs continue to be one of my favorite features. It's such a simple thing but makes a huge difference when you're tossing it in a bag. No snagging, no scratching other items. The size is still impressively small for the amount of power it delivers.
This is one of those products that just works. No fuss, no weird charging issues, just plug it in and go. If you already have the 47W version and need more power, this is a no-brainer upgrade. If you're choosing between the two, I'd say go with the 65W unless you're absolutely certain you'll only ever charge phones and tablets. The peace of mind of having extra power available is worth it.

Great low cost USB C to 4K HDMI splitter adaptor
Color: Black
The Anker USB C Hub 5-in-1 USBC to HDMI splitter with 4K display with one powered USB c and 2 USB A ports works flawlessly and is a perfect travel companion or simple and inexpensive desktop dock to connect a moderan USB C only laptop to a large monitor up to 4K resolution. It supports 4K at 60 Hz so not for high speed gaming but it is flicker free for daily work where running at 60 Hz provides a clean looking 4K display. The USB C and USB A ports work perfectly. I already have four of these in different port configuration but wanted the 4K extension for travel and this was the best one for quality and bang for the buck.

Compact, Travel friendly, Works well with ROG ALLY
Color: White
This is a compact and well built adapter, and it is travel friendly. I use it for my ROG ALLY when I don’t want it docked and still need charging and other device inputs. It has just about enough ports for what I need, usb-c power delivery port for charging (ROG ALLY can still run at maximum performance using this with a 100W charging brick and a cable that allows 100W power pass through). I use the remaining USB-C port and two USB-A ports for external hard drives or gaming controller 2.4Ghz receiver. Transferring files between ROG ALLY and an external SSD with this adapter is fast, could reach above 380 mb/s. All the device inputs were as advertised, “plug and play”. The hdmi port also gives me an option to connect my ROG ALLY to TV when I don’t have the dock which takes up more space for traveling. One thing to note, you will have to use the USB-C port on your PC which provides more power (usually at the back and not on the front of the pc), if not plugged in to a power source. When I received my first order, I plugged it into the front USB-C port of my mini PC, just for my wired keyboard and mouse, the computer didn’t recognize it and couldn’t get any input from my keyboard and mouse. I returned the first one and thought it wouldn’t work as I expected. A few days later when I was using another Anker 7 in 1 USB-C adapter, I ran into the same issue but I know that adapter had been working well, then I realized I had to plug it into the port on the back of the PC. So I got this again and tried, it just worked like a charm. Hope they actually mentioned it on their product page so I wouldn’t have to return the first one. The cable length on this adapter is just right, not too long or too short when using with ROG ALLY (not hanging, since the cable is pretty sturdy, when I picked up the ROG ALLY, the adapter just comes along).
