SENNHEISER INTRODUCES AUDIOPHILE HD 800 HEADPHONES AT WINTER NAMM
LAS VEGAS, NEVADA – JANUARY 2009: A completely novel type of transducer and an innovative ear cup design are two of the key design features of Sennheiser’s new top-of-the-range HD 800 headphones being introduced at Winter NAMM 2009. This audiophile model, which is sure to remind high-end enthusiasts of the company’s legendary Orpheus headphones, offers brilliant sound imaging and impressive spatiality through the use of a 56mm sound transducer – currently the largest to be found in any dynamic headphones – and an ear cup design that directs sound waves to the ear at a slight angle.
The vibrating part of the diaphragm is not a circular surface area but a ring, which is able to set the entire air volume over the transducer into motion, generating the full-bodied sound of the HD 800. This annular design, patented by Sennheiser, solves the problems relating to the dynamic transducer principle for the first time. more
