Las Vegas, January 10, 2012 â€“Sennheiserâ€™sÂ high-end world has plenty of excitement to offer. At this yearâ€™s Consumer Electronics Show in Las Vegas, the audio specialist is unveiling a set of new premium headphones, the HDÂ 700. These fully open dynamic stereo headphones combine high-end sound with an innovative headphone design.
â€œThe HD 700 features a perfect combination of outstanding acoustic properties and sophisticated product design,” said Maurice QuarrÃ©, Director Product Lifecycle Management Sennheiser Consumer Electronics. â€œIts styling and material selection have been thought through down to the finest detail in order to fully exploit the sound potential of the acoustic unit.”
The ear cups are designed in such a way that the sound waves are directed to the ears at a slight angle. This results in an impressively natural listening experience. The ear cups themselves have a completely open design. This not only ensures a highly transparent sound but also clearly displays the “heart” of these exciting headphones: the 40 mm Duofol transducer. Its powerful neodymium magnet systems guarantee detailed, lifelike audio reproduction from 10 to 42,000 Hz.
Small details for a great sound
The endeavour to fully exploit the sound potential of the premium headphones led to a further small but effective innovation: a ventilated magnet system. The idea is actually quite simple. “The up and down motion of the diaphragm produces an air flow in the magnet system housing that causes the diaphragm to wobble slightly,” explained Axel Grell. “By positioning precisely defined holes in the housing directly under the magnets, we can cause the air to flow in a specific direction. This minimises the wobbling motion of the diaphragm.” And the result is impressive: with total harmonic distortion of less than 0.03Â percent (at 1Â kHz and 105Â dB sound pressure level), the HDÂ 700 offers brilliant trebles, precise bass reproduction and a crystal-clear sound. Dips in the bass level are effectively suppressed by the patent-pending multilayer design of the headband.
Designed to meet the highest demands
The new HD 700 will be available in shops from March and carries a street price of $999.95.
