The Sennheiser EW-DX SK 3-PIN is a digital bodypack wireless transmitter compatible with EW-DX wireless receivers. Lightweight and comfortable for performers and presenters to wear, the bodypack features a rugged, all-metal housing well suited for daily use in conference rooms, houses of worship, or on stage.
The EW-DX SK 3-PIN is equipped with a 3-pin LEMO connector that accommodates the compatible lavalier or headset microphone of your choice, or an adapter cable for guitar and bass. With a remarkable 134 dB dynamic range on its input, the transmitter can handle a wide variety of sound sources, including loud vocalists and performers, connections to musical instruments, and even line-level signals from mixers, all without requiring any gain adjustment.
Features at a Glance
- The EW-DX SK 3-PIN features a mute button that can be locked out and overridden from the receiver or a mobile device during a performance. It quickly pairs with the receiver via Bluetooth at a distance up to 120', at the press of a button.
- The persistent e-Ink display helps you quickly name and identify the transmitter and allows you to see parameters, even when the unit is powered off.
- The transmitter provides up to 8 hours of operation on two AA batteries (included) or 12 hours with a BA 70 lithium-ion rechargeable battery pack (available separately). External charging ports allow for in-transmitter charging using the CHG 70N network charging dock (available separately).
- The EW-DX 3-PIN system utilizes an equidistant tuning grid that equally spaces 3480 frequencies across its wide 87 MHz bandwidth to prevent disruptive intermodulation issues that occur when multiple transmitters operate in confined spaces.
- The system can be expanded with multiple transmitters and receivers to offer up to 146 channels in equidistant tuning grid mode, and up to 293 channels in Link Density mode.
- The EW-DX SK 3-PIN is backward-compatible with EW-D receivers.
Compatible Mics and Instrument Cable with 3-Pin LEMO Connector
- The sweat-resistant, subminiature MKE 2 omnidirectional lavalier mic offers a pristine, broadcast-quality sound and is easy to conceal.
- The unobtrusive ME 2 omnidirectional lavalier mic provides a forgiving pickup pattern that captures sound equally well in every direction.
- The ME 4 cardioid lavalier mic offers a narrower, feedback-resistant pickup pattern for louder events.
- The ME 3 cardioid headset mic provides enhanced speech clarity for lectures and presentations.
- The CI 1 instrument cable lets you connect the bodypack transmitter to a guitar, bass, or keyboard.

Best Sleep Shorts EVER ♥️
Color: Multicolor a (5-pack), Size: Medium
Love, love, LOVE these bamboo BoyShorts! I wear them for sleeping because they’re incredibly light, soft and comfortable while still having a great liner. They fit to my body while not feeling tight, snug or restrictive. Soooo comfortable. I’m 5’8” 145 lbs and went with Medium. ♥️

Amazing fit!!!
Color: Multicolor a (5-pack), Size: Large
These are quite literally the best underwear I have ever worn. I am going to replace all of my underwear with just these. I got the shorter boy shorts cut and they are amazing. These let my body be the shape that my body is, no squeezing or tight waist band. I feel so normal and comfortable in them, they’re breathable and soft!! I absolutely love them after so much trial and error with underwear I finally found the ones!

Highly recommend during pregnancy and to wear around the house!
Color: Multicolor a (5-pack), Size: X-Large
Love!! I’m currently 33 weeks pregnant. I’m 5’6” and pre pregnancy weight I would fluctuate between 132-140 lbs easily. I now weigh 162 lbs and my hip is now measuring 40 inches.
I bought the XL in the dark grey/black so that it wouldn’t be tight at all around my belly and I absolutely love them! Stretchy, comfortable, breathable. They aren’t loose around my thighs and I can tell they are gonna be nice to wear during post partum. I wear them around the house with an open robe and a bralette for the ultimate comfort.
If I were to buy them before pregnancy, I’m positive that a large would have fit beautifully, even though the small/medium measurements on the size chart would have been my pre pregnancy weight, I know they would have been too tight. I detest tight underwear!
Highly recommend!

Cute and Comfy
Color: Multicolor B (5-pack), Size: Medium
These are cute and comfy with a great fit. True to size they are cool and comfortable for everyday wear. I was going to order more but the price went up so I'm just waiting for it to go back down to order again.

Not what I’d hoped
Color: Multicolor a (5-pack), Size: Small
The fabric is nice, soft without being overly bulky. The design was almost what I wanted. I’ve been trying to find underwear that won’t ride up and is comfortable to wear under leggings. The fabric has a LOT of stretch around the legs and deforms quickly. Then it rides up and wrinkles. Smaller leg openings might make the difference.
