"These Will Surely Impress"
Taking full advantage of Sennheiser's mastery of acoustic engineering, the HD 700 delivers the type of advanced sonic experience seldom encountered in headphones.
"If the company's legendary, top-of-the-line HD 800s were always in your sights but out of reach, the HD 700s might be exactly what you're looking for," reports Mario Aguilar at Gizmodo.com.
"For those true audiophiles and lovers, these will surely impress," says Cory Gunther at SlashGear.com for January 20, 2012.
Thanks to a proprietary angled transducer, the HD 700 angles sound to mimic the positioning of a set of reference monitors. This, in tandem with the DuoFol diaphragm, provides a wide sound stage with ultra-fast response and rest times. Close your eyes and you'll imagine that you are in the front row of a live musical performance.
Ventilated Magnet System
A great headphone transducer is only half of the equation. Sennheiser's acoustic team used the HD 700 project as motivation to obtain a cleaner, purer sound in unconventional ways and thus the patent-pending ventilated magnet system was born. By venting the magnet which lies behind the diaphragm, airflow was properly managed and overall turbulence was minimized. The result was greater purity.
The outer transducer chassis was also meticulously engineered for superior sound quality. By utilizing a special steel mesh molded to the natural shape of the acoustic sum, the Sennheiser 'open-aire' system remained pure while properly directing airflow. These techniques combine to support the impeccable capabilities of the transducer with world-class, practical acoustic management.
Vibration Damping Frame
Borrowing a design cue from the flagship HD 800, the HD 700 also utilizes a vibration damping frame. Strategic layering of materials helps prevent unwanted resonances from entering the acoustic chamber. The culmination of these technologies lends to the warm, detailed, balanced and utterly revealing sonic signature. |
