Its acoustic design ensures brilliant natural high-end sound reproduction and reveals even the finest details in the music.Features:New benchmark in portable audioUltimate precision & craftsmanshipAdjustable ear hooks and choice of ear adapters including memory foamX3R technology: TrueResponse transducer combined with three Helmholtz resonator chambers and acoustic vortexPrecision-milled and anodized aluminum housingNatural Balanced SoundInnovative X3R technology for an intense listening experienceGerman-made 7mm TrueResponse transducer for natural balanced soundUnique triple-chamber absorber system refines and smoothens high frequencies to perfectionAcoustic vortex milled into the nozzle ensures natural sound wave propagationSpecially developed membrane foil minimizes resonances and distortionUltimate Precision & CraftmanshipDesigned engineered and manufactured in GermanyTransducers are matched during the manufacturing process to practically eliminate varianceOne-piece housing is precision-milled from a single block of aluminumHand-assembled by a specialist team at Sennheiser´s headquarters to razor-thin tolerancesGlobal 2-year warrantyDurability & ComfortLightweight high strength housing offers exceptional durability and long-lasting aesthetic beautyForm-fitting anodized aluminum housing seats securely in the earSelection of silicone and foam ear adaptors ensure an optimal fit for high noise isolationAdjustable ear hooks adapt to the natural shape of the ear for a tailored fitPara-aramid reinforced cables with gold plated Fidelity+ MMCX connectors ensure the longevity of useA choice of balanced and single-ended cables (2.5mm/3.5mm/4.4mm) for easy connectivityIntroducing the X3R TechnologyInnovative 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.
