Since university-lecturer-turned-entrepreneur Fritz Sennheiser founded Laboratory Wennebostel in a German farmhouse back in 1945, the company has evolved into one of the world’s leading audio specialists. Sennheiser has produced many significant models in its field, including the company’s very first in-house product, the MD 2 microphone (1947) and the world’s first-ever open-back headphone, the HD 414 (1968).

In celebration of its 75th anniversary, Sennheiser is now bringing the retro aesthetic of its HD 414 headphones to the more recent HD 25 model. First hitting the market in 1988, the HD 25 was originally conceived as a professional monitoring headphone. Later, it found its way onboard the Concorde as high-class in-flight headphones and is today still one of the go-to models for many music professionals. 

The special anniversary edition HD 25 headphones are limited to 25,000 examples worldwide, with nostalgic packaging featuring an archive image of a woman wearing a pair of the original HD 414. In addition to the standard black pads, the HD25s also include a pair of yellow pads in a similar fashion to those on the iconic HD 414. 

Sennheiser’s 75th-anniversary website also offers us an opportunity to revisit its history and connect with people who share the same passion for music and strive for a top-notch audio experience.
