About Sennheiser

In June 1945, Prof. Fritz Sennheiser founded the Wennebostel Laboratory, which initially produced measuring equipment. Commissioned by Siemens in 1945, the young company developed the MD-1 microphone, which was launched in 1946. After the development of further microphones, the company was renamed Sennheiser Electronic in 1958. Two years later, Sennheiser introduced the MD 421 dynamic microphone, which is still in production today and still held in high esteem by many sound engineers. Further groundbreaking developments, such as the HD 414 headphones and the classic MD 441 microphone, hugely enhanced the company's international reputation, eventually making Sennheiser one of the leading manufacturers of microphone and headphone systems in the world.

Precision monitoring for every scenario

Wireless in-ear monitoring systems such as the Sennheiser ew IEM G4 have transformed live monitoring by eliminating stage wedges – thus reducing feedback – and delivering precise, tailored mixes that allow performers to focus fully on their craft. Its rugged construction will capably withstand the demands of touring, while its versatility extends to conference setups requiring simultaneous translations or film sets needing reliable communication. From bassists appreciating the clarity of their low B-string to vocalists perfecting their harmonies, from presenters moderating multilingual conferences to crews managing complex events, the Sennheiser ew IEM G4 ensures dependable monitoring in every professional context.

Rien à redire, excellent module in ear
Charly44 06.09.2021
Remarquable produit, d'excellente qualité. Le son est incomparable par rapport à d'autres produit déjà testé.
Très facile d'utilisation et la fonctionnalité de synchronisation est très pratique et permet de partager les règlages effectués sur l'emmeteur au recepteur.
Le son est remarquablement bon et la portée est impressionnate (testé sur plus de 30m avec plusieurs murs entre l'emetteur et le recepteur.

A great buy
Tronduss 04.04.2026
The Sennheiser EW IEM G4 has honestly been a game changer for me on stage.

From the first time I used it, the sound quality stood out immediately – clean, detailed, and super reliable. It gives me full confidence during live performances because I can hear exactly what I need, when I need it. No surprises, no guessing.

What really impressed me is how rock solid the wireless connection is. Even in environments with a lot of RF noise, it just works. That kind of reliability is priceless when you're performing live.

The build quality also feels exactly like you’d expect from Sennheiser – durable, professional, and made for real-world use. This is gear you can trust gig after gig.

Battery life is more than enough for long sessions, and the interface is generally easy to use once you get familiar with it.

That said, there’s one small thing that feels a bit confusing:
You scan for frequencies on the receiver, but when syncing, the receiver takes the frequency from the transmitter instead. It works fine, but the workflow feels a bit backwards and could definitely be more intuitive.

Still, that’s a minor issue in an otherwise fantastic system.

Overall, I absolutely love this unit. It delivers where it matters most: sound, reliability, and confidence on stage.

If you’re serious about your monitoring setup, this is an easy recommendation.

Excellent performance
Zak K 22.05.2025
This product keeps things simple for you! It's quick to set up. But the catch is you may need to set it up again at every gig because it doesn't remember its settings, and the receiver and transmitter can't find each other. One of the most useful settings to prevent unpleasant clipping, is to set the boost to -+6dB, while limiting it by -6dB. Seems counterintuitive but it helps greatly. There is no latency and it cuts through crowds and human bodies in a full venue with standing guests.
