Every Detail Matters.

The IE 900 from Sennheiser sets a new benchmark in portable audio fidelity
through technical innovation (X3R), 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 unites the German-made
7mm TrueResponse transducer with specially developed
membrane foil and acoustic back volume, 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
