This voicing lends a presence and intimacy that brings listeners closer to the music, allowing them to discover new accents and details. However, arriving at this level of poise and naturalness was not without challenges. When similar sounds occur in a track simultaneously, for instance, it can become difficult for the human ear to resolve all the nuances. The IE 600 integrates dual two chamber absorbers (D2CA) which capture and attenuate these masking frequencies, revealing even the finest textures of your music.

Production of the amorphous metal housing takes place in Germany and includes both automated and manual steps..

Ultimate Shape

A computer-controlled laser sinters a thin coat of metal powder, welding the molten alloy to the already hardened material beneath it. Layer by layer, the part builds up to its ultimate shape. A technician then removes any artifacts of the manufacturing process by hand.

Sophisticated surface treatment

After thorough cleaning, steel shot blasting, polishing, and sophisticated surface treatment, the housing assumes its final, extremely durable aesthetic. Even daily use leaves practically no evidence in the form of scratches or wear.

Each TrueResponse transducer is assembled by Sennheiser and built to last.

Exceed the expectations of audiophiles

One of the most advanced production lines of its type in the world, our manufacturing facility has a singular purpose — to exceed the expectations of audiophiles. That’s how we consistently achieve channel matching that makes left-right differences nearly undetectable. And total harmonic distortion to rival anything on the market.

Robust protection

All this product quality is cocooned inside extremely resilient amorphous metal, ensuring your IE 600 earphones will remain in mint condition for countless years. With robust protection against corrosion and marks from wear, the IE 600 was designed to keep delivering acoustic — and visual — joy for decade
