Hello Head-Fi!
Today is an exciting one as we officially unveil the IE 600—the third family member of our audiophile in-ear range. With a housing crafted from NASA-grade materials and sonic lineage to the IE 900 and IE 300’s TrueResponse transducers, the IE 600 brings audiophiles a lifetime of exquisite sound with every listen. Each earpiece is 3D printed (more on that) with ZR01 amorphous zirconium via a precision manufacturing process for unmatched durability. The insides are just as special, producing an intimate sound that perfectly balances realism and expression.
Exceptional In Every Detail
The IE 600's meticulous craftsmanship complements its world-class signature sound. The amorphous zirconium housing has an atomic structure similar to glass yet triple the hardness of steel, thus it can be shaped with uncanny precision and consistency to offer our complex transducer system an ideal environment to reproduce larger-than-life sound. This AMLOY-ZR01 material is actually found on the drilling head of the NASA Mars Rover, applied specifically for its toughness in extreme conditions. The earphone nozzles contain dual-chamber frequency absorbers to unmask critical details in your music—when combined with the 7mm TrueResponse transducer, the results are breathtaking vocals, resolute treble detail and clear bass extension. These casings, made in Germany by Heraeus, conclude their journey at our Ireland manufacturing plant for assembly and rigorous channel matching.

It’s All About Connection
Included with every IE 600 are two para-aramid reinforced cables: a single-ended cable with a 3.5mm plug termination, as well as a balanced cable with a 4.4mm plug. The IE 600 uses gold-plated Fidelity+ MMCX connectors that provide utmost contact integrity. Each housing-side receptacle is seated within a recessed, 4.8mm-wide socket to provide wearers with robust strain relief. Three sizes of silicone and viscoelastic eartips ensure a comfortable coupling for optimum bass response and environmental isolation. A debris cleaning tool and clothing clip stash away in the zippered storage case so you can enjoy the IE 600 wherever you decide to have your hi-fi fix.
