Through a patented 3D printing process, the housings of the new Sennheiser IE 600 are made from ZR01 amorphous zirconium, a metal with a glass-like atomic structure that gives it triple the hardness and bend resistance of high-performance steel. One of the only other places ZR01 amorphous zirconium is used is in the aerospace industry, such as in the drilling head of the NASA Mars Rover. Designed in Germany, they are manufactured at Sonova Consumer Hearing’s transducer production facilities in Ireland to the very highest standards. One of the most advanced production lines of its type in the world, it was designed to support the highest manufacturing standards, like industry-leading channel matching.
“At the audiophile development team, we intently listen to the feedback of our incredibly passionate customers. The IE 600 delivers a neutral reference tuning in combination with our industry-leading miniature transducer technology.” says Jermo Köhnke, Product Manager for Sennheiser Audiophile. “The paradigm-shifting acoustic performance is appropriately clad in highest-performance amorphous zirconium. The IE 600 will be a reference for the most demanding mobile audio enthusiasts.”
Just as distinctive is the IE 600’s exceptional sound performance, with an innovative acoustic back volume and precision-molded resonator chambers. This voicing lends a presence and intimacy that brings listeners closer to the music, allowing them to discover new accents and details. The nozzle houses dual resonator chambers that are the key to the earphones’ high-fidelity sound. Precisely formed to tight tolerances, these chambers make even the finest textures of a listener’s music audible by eliminating masking resonances .
The IE 600 achieves virtually distortion-free reproduction of music through Sennheiser’s TrueResponse transducer, a single 7 mm driver responsible for the extra-wide frequency range and ultra-low distortion of these earphones. Within the IE 600, this system and the acoustic back volume has been tuned for a tonally neutral, intimate and emotional sound. This ensures a true-to-life voicing that is especially expressive for vocal performances. The acoustic system has also been optimized to produce a steep bass slope resulting in a powerful yet fast and accurate low-end response.
The gold-plated MMCX connectors are recessed in its housing for greater stability and guidance. They support cable diameters of 4.8 mm and smaller, allowing listeners to plug into a wide range of audio sources as well as hi-fi components with balanced outputs. To allow the choice between para-aramid reinforced unbalanced and balanced cables, both 3.5 mm and 4.4 mm sizes are included with the IE 600. Two different styles of earbud tips — silicone and memory foam — provided in three sizes will establish a comfortable seal in any ear, while flexible, adjustable ear hooks further enhance the long-lasting comfort for extended listening sessions. The IE 600 fits into the range between the IE 300 and IE 600; it will be available this Spring/Summer for 699 EUR (MSRP).
