Balanced, neutral voicing

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.

Discover new accents and details

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.

Stronger than steel, built to last

Researchers have worked for many years to perfect amorphous metals for manufacturing.

Lustrous, satiny surface

The 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 extraordinarily resistant to corrosion and scratches.

New material

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.

Extraordinary resilience

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.

Get closer to your music.

Whatever type of music moves you, with the IE 600 it moves you more. Enjoy not only the notes but also the subtle scratch of the bow on the string, the faint chirp of fingers gliding to the next chord on the guitar. Exquisitely neutral acoustic voicing brings your music closer and makes it more alive and vivid, yet pure and natural. Within this delicate balance, the IE 600 nevertheless manages to incorporate a powerful yet fast and accurate low-end response. It’s all in a day’s work for Sennheiser’s TrueResponse transducer, the single 7 mm driver responsible for the extra-wide frequency range and ultra-low distortion of the IE 600.

Automated manufacturing, handcrafted finish

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 a 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.

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 decades.

The comfort of a tailored fit

The IE 600 packs big sound into a small, ergonomic package.

Greater stability and guidance

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.

Long-lasting comfort

Choose between pyramid 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 long-lasting comfort.
