The chasiss of the IE 600 is made from ZR01 amorphous metal using a patented 3D printing process. The special metal with a glass-like structure is said to have three times the hardness and bending resistance of high-performance steel. The surface is additionally supposed to be exceptionally resistant to corrosion and scratches.
Developed in Germany, the earphones are manufactured at Sonova Consumer Hearing's state-of-the-art, company-owned facility in Ireland. During manufacturing, the drivers are automatically paired so that the frequency-dependent amplitude response of the left and right earpieces is said to be nearly identical.
According to Jermo Köhnke, product manager for Sennheiser Audiophile, the tonal tuning of the IE 600 was deliberately made to be neutral. Good sound is said to be provided by, among other things, an innovative acoustic "back volume" inside the earphone as well as precision-engineered resonance chambers. Dual-chamber absorbers (D2CA) are located in the sound path between the transducer and the ear canal and aim to absorb masking frequencies. Sennheiser's 7mm TrueResponse drivers are also said to cover a particularly wide frequency range.
The IE 600's gold-plated MMCX connectors are embedded in the headphones' housing for better stability and guidance. Customers can choose between para-aramid-reinforced unbalanced or balanced cables, with 3.5mm and 4.4mm jacks included. Ear tips of either silicone or memory foam in three sizes are said to improve comfort along with the ear hooks, which can be flexibly adjusted.
In Germany, the Sennheiser IE 600 is supposed to be available starting in spring/summer 2022 at a price of around 700 euros.
