Sennheiser: German Excellence in Professional Sound Since 1945

Sennheiser, or the Story of a German Passion for Sound

When it comes to professional sound, one name immediately stands out: Sennheiser. Founded in 1945 by Fritz Sennheiser in a small laboratory near Hanover, the German family business has become, over eight decades, one of the absolute benchmarks of global audio. Still independent today, Sennheiser equips the world's greatest recording studios, festival stages, television sets, and conference rooms around the globe. From microphones to headphones and wireless systems, the brand embodies the excellence of German engineering applied to sound.

Green Musicians invites you to discover the Sennheiser universe: its history, its iconic products, and how to find the gear of your dreams at the best price on our marketplace.

From 1945 to Today: The Epic Journey from a Small Lab to a Sound Empire

It all began in the immediate post-war period. Fritz Sennheiser, a young engineer passionate about telecommunications, founded "Laboratorium Wennebostel," or Lab W, with seven employees. The first product was not a microphone but a tube voltmeter. However, as early as 1947, the company developed its first microphone, the MD 1, laying the foundation for what would become an audio dynasty.

The 1950s marked the arrival of the legendary MD 21, a dynamic microphone that remained in production for over sixty years. In the 1960s, Sennheiser revolutionized the market with the first shotgun directional microphone, the MKH 805, paving the way for major innovations in broadcast and cinema.

The 1980s saw the company diversify with the launch of its first headphones and wireless systems. The HD 414, the world's first open-back headphones, sold over ten million units. Now led by the founder's sons, Daniel and Andreas Sennheiser, the brand continues to innovate with technologies such as AMBEO (3D spatial audio) and the revolutionary Spectera digital wireless system.

Sennheiser Microphones: The Professional's Essential Tool

If there is one area where Sennheiser excels, it is microphones. The catalog is so vast that it covers absolutely every need: stage, studio, broadcast, cinema, conference. The MD 421 is undoubtedly the brand's most iconic microphone. Launched in 1960, this large-diaphragm dynamic microphone is still manufactured today, and for good reason: its versatility is legendary. You'll find it on drum toms, guitar amps, brass instruments, and even in broadcast voice applications. Its new version, the MD 421 KOMPAKT, awarded a TEC Award in 2026, carries on this legacy in a modernized format.

The evolution range forms the core of the affordable live and studio lineup. Microphones such as the e 835, e 845, and e 906 are absolute references for the stage: rugged, precise, they handle high sound pressure levels without flinching. For the studio, the MKH series (RF condenser microphones) offers unmatched transparency and detail, used by the world's top sound engineers for orchestral recordings, natural ambiences, and sound design.

Whether you are a singer, drummer, guitarist, or sound engineer, there is a Sennheiser microphone made for you. Discover the microphones available on our marketplace through our dedicated search.

Sennheiser Headphones: From DJ to Studio to Audiophile

The HD 25 is without question one of the most iconic headphones in music history. Originally designed for monitoring in noisy environments, it has become the absolute standard for DJs worldwide. Lightweight, rugged, with exceptional passive isolation and a frequency response curve tailored for mixing, the HD 25 is still manufactured after more than thirty years of service.

For studio work, the HD 490 PRO is Sennheiser's modern reference. Designed for mixing and mastering, it delivers an open, precise soundstage with exceptional wearing comfort even during long sessions. The HD 600 range (HD 600, HD 650, HD 660S) represents the pinnacle of audiophile listening, with open-back transducers offering near-surgical neutrality in frequency response.

On the consumer side, the Momentum range combines premium design and Sennheiser sound quality in Bluetooth headphones with active noise cancellation. An elegant bridge between the professional world and demanding on-the-go listening. Browse our selection of Sennheiser headphones on Green Musicians.

Wireless Systems: Freedom at the Service of Performance

Sennheiser has been a pioneer of professional wireless systems since the 1980s. The evolution wireless range (G3, G4 series, and now digital EW-D) has become the standard for musicians, sound technicians, and production companies. Reliability, audio quality, and ease of use: the formula has proven itself on thousands of stages around the world.

The new Profile Wireless is aimed at content creators, videographers, and mobile journalists with a compact all-in-one system: lavalier mic, handheld mic, and receiver integrated into a charging bar. Finally, the Spectera system represents the revolution in wideband digital wireless, using WMAS (Wireless Multichannel Audio Systems) technology to multiplex an unprecedented number of audio channels in a reduced spectrum.
