Sennheiser latest headphones are built from the same metal used for NASA's Mars Rover's drilling head.
The upcoming IE 600 in-ear headphones were constructed using a metal called ZR01 amorphous zirconium through a "patended 3D printing process".
In a press release online, the company said: "Through a patented 3D printing process, the housings of the IE 600 have been crafted 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 — besides ultra-high-end products like the IE 600 — is in the aerospace industry, such as in the drilling head of the NASA Mars Rover, where ultimate toughness in extreme conditions is required.
"Through multiple elaborate treatment processes, a beautiful surface finish is achieved that is extraordinarily resistant against corrosion and scratches."
The IE 600 will reportedly act as a midway point between the more affordable IE 300 and the preimum IE 900.
Meanwhile, the headphones will also come with acoustic back volume and precision-moulded resonator chambers.
The company also said its TrueResponse driver will give the headphones a "tonally neutral, intimate and emotional" sound.
They added: "This ensures a true-to-life voicing that is especially expressive for vocal performances. The acoustic system has also been optimised to produce a steep bass slope resulting in a powerful yet fast and accurate low-end response."
