Ultra-reliable In-ear Performance

To perform your best, you need to hear yourself clearly. That's where the Sennheiser ew IEM G4-Twin comes in — and you get the added benefits of a wireless in-ear system. You can hear anywhere on stage and there's less stage noise. Beyond that, in-ears aren't prone to feedback. With the Sennheiser ew IEM G4-Twin, you get all the components you need: a high-quality rackmountable transmitter with 1,680 tunable UHF frequencies, two bodypack receivers, and two pairs of IE 4 earphones. With the ew IEM G4-Twin, you'll enjoy increased bandwidth and power over previous generations, a transmission range up to 330 feet, and backward compatibility with previous evolution systems.

You can rely on this rackmount transmitter

The rugged SR IEM G4 is ready for the road with its proven transmission reliability and inspiring flexibility. It operates up to 61 channels with up to 42MHz of bandwidth and 1,680 selectable frequencies. Plus, it offers higher RF power of up to 50mW for crystal-clear reception. An upgraded infrared interface results in faster synchronization. The SR IEM G4 also features a user-friendly menu with a convenient jog wheel and an OLED display with automatic dimming, blue sync LED, red warning LED, and dedicated Escape button.

A compact receiver packed with the features you need

The EK IEM G4 features adaptive diversity for super-reliable reception. Its headphone cable is utilized as a second antenna to banish audio dropouts. Operating the EK IEM G4 is also easy due to its intuitive menu navigation and highly-visible backlit graphics display. A switchable Hi Boost and a multi-level limiter complete the package.

Peace of mind
I know when I use these I'm going to get the cleanest sound possible. With its multi band channel clarity and sleek design. I am ready for any stage.
Rated 5/5
Great IEM system!
This is a great IEM system. Sounds fantastic and works great. I have about 20 hours on it and still running the batteries that came with it. I just figured out how to run two different mixes through this so our bass player will start using my extra pack. Very Happy with this and thanks to David Winkert and all the folks at Sweetwater for the awesome service as always!

Sweet Sound!
I pair these with triple-driver Westones for our worship band. We have had no problems to this point and they sound very nice. I will say that there is another company out there that "sure" would like you to think they have the best products for in-ear sound. But our band has moved away from those products simply because they don't have the same clean sound and clear bottom end. If you're new to in-ears, this is a great way to introduce yourself to that tool without being frustrated by static and thin sound waves.

From their studio-standard MD 421 II drum mic to their trusty headphones and ultra-reliable wireless systems, there are countless good reasons why the artists and engineers here at Sweetwater are quick to recommend Sennheiser products. In our personal studios, you'll find plenty of HD 280 Pro headphones, e609 Silver cab mics, and other staples, while many of us rely on EW wireless in-ear systems onstage. Our long association with Sennheiser means we constantly have their latest products in stock and in our hands, so we're ready to tell you all about them. If you're looking for Sennheiser gear, then get the information you need from people who use it - trust your Sweetwater Sales Engineer.
