Music, Sound, and Audio Technology
(Las Vegas, NV) Sennheiser's high-end world has plenty of excitement to offer. At this year's Consumer Electronics Show in Las Vegas, the audio specialist unveiled a set of new premium headphones, the HD 700. These fully open dynamic stereo headphones combine high-end sound with an innovative headphone design. "The HD 700 features a perfect combination of outstanding acoustic properties and sophisticated product design," said Maurice Quarré, Director Product Lifecycle Management, Sennheiser Consumer Electronics. "Its styling and material selection have been thought through down to the finest detail in order to enhance 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 endeavor to fully enhance 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," Grell explained. "By positioning precisely defined holes in the housing directly under the magnets, we can cause the air to flow in a specific direction. This minimizes the wobbling motion of the diaphragm." And the result is impressive: with total harmonic distortion of less than 0.03 percent (at 1 kHz and 105 dB sound pressure level), the HD 700 offers brilliant trebles, precise bass reproduction and 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 are available in shops starting March 2012. Resources: ADVERTISEMENT
