TrueResponse Transducers with X3R Technology for Balanced Sound Made in Germany
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.
