With the launch of the new IE 800 S, Sennheiser has updated its groundbreaking in ear IE 800 headphones, bringing even more sound quality and subtly refreshed looks. The IE 800 S redefines the benchmark for distortion-free in ear performance. Sennheisers Extra Wide Band (XWB) proprietary transducers deliver an exceptionally detailed, lifelike sound image, with brilliant trebles and a precise and newly improved bass sound. The IE 800 S employs Sennheisers patented dual-chamber absorber (D2CA) system, which removes undesired resonances that can obscure the finest nuances of sound. The resulting high end listening experience is further enhanced by a choice of cables with 4 pole 4.4mm Pentaconn and 2.5mm balanced connectors, in addition to the standard cable with a 3.5mm jack.
