The new IE 900 from Sennheiser sets a new benchmark in portable audio fidelity through technical innovation, meticulous attention to detail, and an uncompromising demand for perfection.

The IE 900’s acoustic design ensures brilliant, natural high-end sound reproduction. It features a refined version of Sennheiser’s 7mm audiophile Extra Wide Band (XWB) transducer system, engineered to tighter tolerances and expertly tuned for even greater fidelity, and a unique triple-chamber absorber (T3CA) system. These advances produce high dynamics in a precise and controlled manner, so music stays distortion free and extremely transparent at any listening volume.

The IE 900 is manufactured by a specialist team at Sennheiser’s headquarters in Germany to the highest production standards in the audio industry, ensuring exceptional lasting quality.
