The Sennheiser HD 660S2 courageously follow in the footsteps of their predecessors and, like the latter, turn out to be a crossover between a tool for pleasurable listening and professional work equipment.
Sennheiser – a family business from Lower Saxony with worldwide success
The audio specialist Sennheiser, based in Wedemark near Hanover (Germany), is one of the world’s leading manufacturers of headphones, microphones and wireless transmission technology, with its own factories in Germany, Ireland and the USA.
Sennheiser History
The history of audiophile sound begins with the HD 414. The world’s first open back headphones revolutionised the headphone market in 1968. To this day, the HD 414 remains one of the best-selling headphones in the world, with over 10 million units sold.
Another milestone follows when Sennheiser engineers combine the principle of open back headphones with the principle of electrostatic sound transducer technology for the first time. In 1977, Sennheiser presents the Unipolar 2000 and delights the experts. The underlying principle is once again an innovation in the audio world: in the electrostat, high voltage is applied to two grid-shaped electrodes. As with loudspeakers, this deflects a coated foil membrane in time with the music. This enables extremely fine resolution and a low distortion factor.
In 1991, the electrostatic Orpheus HE 90/HEV 90 stood out from a veritable flood of new headphones. With no less a claim than to build the best headphones in the world, the Sennheiser developers had once again gone to work and exceeded the expectations of the audio industry with this electrostat and its impressive tube amplifier. Two platinum-coated membranes oscillate between gold-coated glass electrodes. A 500-volt tube amplifier provides sufficient voltage for the Orpheus to develop its full sonic potential. Due to its extremely elaborate workmanship, the Orpheus is limited to 300 copies. To this day, the legendary headphones remain the benchmark for audiophile listening and all high-end models developed by audio specialist Sennheiser.
