Bringing you closer to your music

The Sennheiser IE 600 has a neutral yet captivating quality that makes music sound alive and vivid. The balanced and detailed sound is pure and natural, so you hear music exactly as the artist intended. You'll enjoy not just the notes, but the subtle scratch of bow on strings, the faint chirp of fingers gliding across guitar strings, or the nuance in vocals. Bass is fast and accurate, the midrange is clear and nicely tuned, and treble is detailed and sparkly. Hand-finished amorphous metal housing gives the IE 600 a unique look as well as robust protection against corrosion and marks from wear. The The ergonomically designed housings fit snugly in the ear for a comfortable, "barely there" fit.

Amorphous alloys are an extraordinary new class of materials. Our high-tech AMLOY ZR01 is used in components for aerospace and MedTech applications that require ultra-high precision and robustness. We are proud that Sennheiser evaluated our space-grade amorphous alloy and decided to use it for the IE 600.

TrueResponse transducer for a true audiophile sound quality

The IE 600 is a single dynamic driver in-ear monitor. Sennheiser’s TrueResponse transducer is responsible for the extra-wide frequency range and ultra-low distortion of the IE 600. Each TrueResponse transducer is assembled in one of the most advanced production lines of its type in the world. Sennheiser's channel matching makes left-right differences nearly undetectable. And total harmonic distortion to rival anything on the market.

Natural & intimate sound with fast, accurate bass

To achieve a natural sound reminiscent of the neutrality provided by high-end studio monitors, our engineers carefully tuned the acoustic back volume inside the nozzle of the IE 600. 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. Soundstage on the IE 600 is intimate, and the music sounds quite close, as if you were sitting close to the stage or recording booth.

Beautiful, durable, unique design

Researchers have worked for many years to perfect amorphous metals for manufacturing. Th wait was worth it — the zirconium alloy from Heraeus Amloy Technologies we chose for the IE 600 has triple the hardness and flexural strength of high-performance steel. Shock-frozen during manufacturing, amorphous metals never have a chance to form a crystalline structure like conventional metals. The result is a lustrous, satiny surface that is extraordinary resistant against corrosion and scratches. The IE 600 housing is fabricated using metal-powder-based 3D printing that can create any shape imaginable within tight tolerances. Chambers and channels form as part of this additive manufacturing process with no milling required. However, cost does limit the potential applications of this new material. One of the only places you’ll find it — besides ultra-high-end products like the IE 600 — is in the drilling head of a NASA Mars Rover where extraordinary resilience in extreme conditions is required.

Automated manufacturing, handcrafted finish

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

A faithful companion on your sonic journey

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

Small size, comfortable fit

The IE 600 packs big sound into a small, ergonomic package. The gold-plated MMCX connectors are recessed in the housing for greater stability and guidance. They support cable diameters of 4.8 mm and smaller, allowing you to plug into a wide range of audio sources as well as hi-fi components with balanced outputs. Choose between para-aramid reinforced unbalanced and balanced cables: 3.5 mm and 4.4 mm are included, 2.5 mm are sold separately. Two different styles of earbud tips — silicone and memory foam — are provided in three sizes to establish a comfortable seal in any ear. Flexible, adjustable ear hooks further enhance the long-lasting comfort.
