Sennheiser IE 900. Every Detail Matters

The new IE 900 from Sennheiser sets a new benchmark in portable audio fidelity through technical innovation (X3R technology), meticulous attention to detail, and an uncompromising demand for perfection.

Every aspect of the IE 900 has been engineered to work in harmony to achieve the desired acoustic tuning and to reduce resonances and masking effects. Its acoustic design ensures brilliant, natural high-end sound reproduction and reveals even the finest details in the music.

Introducing the X3R technology

Innovative X3R technology, unique to the IE 900, unites the German-made 7mm TrueResponse transducer with specially developed membrane foil, triple-chamber absorber system and acoustic vortex for an intense listening experience

What refines the X3R technology is its three Helmholtz resonator chambers and acoustic vortex which smoothens masking resonance. The three resonator chambers are precision-drilled into the elegant aluminum chassis of the IE 900 and placed between the diaphragm and the nozzle. This complete harmony of systems is at work to unlock the details buried within every track.

7mm TrueResponse Transducer

German-made 7mm TrueResponse Transducer provides extra wide frequency extension and ultra-low distortion for exceptionally natural sound.

The drivers in each pair of IE 900s are matched during our automated transducer manufacturing process to practically eliminate variance.

Specialized Transducer Membrane Ensures Precise Audio

The specially developed membrane foil used in the transducer diaphragm delivers rapid response times for pristine, clear audio across the entire frequency spectrum, even at atypical volume levels.

Triple -Chamber Absorber

The triple-chamber absorber is a sophisticated system of three Helmholtz resonators milled into the solid aluminum housing.

These tiny channels eliminate resonance peaks which can color the sound signature and alter the feel of your music.

Ultimate precision & craftsmanship

Designed, engineered, and made in Germany the one-piece housing is precision-milled from a single block of aluminum on an avant-garde 5-axis-CNC machine.

The demanding milling process takes 40 minutes for each pair of IE 900. Components are hand-assembled by a specialist team at Sennheiser’s headquarters with meticulous attention to detail.

The secure form fitting lightweight high-strength anodized aluminum housing offers exceptional resistance and long-lasting aesthetic beauty. Adjustable flexible ear hooks and a selection of silicone and memory foam ear adaptors in 3 sizes (S/M/L) adapt to the natural shape of your ear for a tailored fit and high noise isolation.
