IE 800    
Dynamic linear-phase driver with extremely wide bandwidth (XWB)    
    
    
Overview    
"At the heart of the IE 800 are several small but invaluable breakthroughs, like the perfected extra wide band (XWB) transducer system. Flaunting a diameter of only 7 mm, it is currently the smallest extra wide-band sound transducer available in dynamic ear canal phones and promises distortion-free sound, capable of performing even at high sound pressure levels.
 With Sennheiser’s state-of-the-art dampened two chamber absorbers (D2CA), ceramic housing and ergonomic, oval-shaped ear adaptors, the IE 800 is loaded with numerous ground-breaking innovations. Designed, developed and produced in Germany, it not only boasts innovative technology but also feature an attractive, yet modern and elegant design. Manufactured with high-quality materials, such as scratch-resistant ceramic for the housing to ensure longevity, the IE 800 ear-canal phones made enjoying audiophile music on-the-go, a reality."
