***New Sennheiser Stock Headband***

More than 60 years of ingenious headphone engineering has been applied into the new HD 800. Incorporating Sennheiser’s most advanced driver technology, these open, circum-aural dynamic stere
Matching these headphones' reference-grade audio performance is their striking and visually effective industrial design. Premium parts have gone into their production - the transducer is encased by a precision material made of stainless steel. The ear pads are handcrafted from a high-quality microfiber fabric. This material is extremely comfortable to wear and easy to maintain. The headband and headphone mounting utilises the most advanced development from the aerospace industry. In terms of connectivity, these headphones utilise specially-designed, four-wire, high-performance connections with Teflon insulation. 
o headphones redefine what reference-level audio is all about. You will form an altogether new height of sonic perspective as you experience a high-fidelity natural hearing experience. Do take note that presently, no other manufacturer has been able to come up as close as the HD 800 in replicating the basic acoustic conditions of natural hearing.
