IE 600 - Exceptional in every Detail.
Simply beautiful sound, and the lengths Sennheiser will go to achieve it — that is the story of the IE 600. These in-ear devices not only reproduce the detail and emotion of a recording, they transcend it. Because each earphone is a masterpiece. From the hand-finished amorphous metal housing to high-end audio components developed and made by Sennheiser, everything is manufactured to the strictest tolerances. The balanced frequency response and extremely durable materials have been engineered to provide clear, natural voicing and a unique aesthetic that will retain its good looks for decades.
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 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.
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.
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.
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.
Choose between paramid 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.

What's in the Box
I have stepped up from the IE300s and these IE600's are a significant improvement. Tighter bass and a much more detailed high end. I also love the cold to the touch feel of the metal.... mmmmm nice
Highly resolving and well tuned IEM. Very comfortable. Weight is less compared to competitors which helps with wearing for long periods of time. My favourite IEM in the sub 1000 dollar price region.
Honestly I never expected such small devices to sound so rich and deep. I miss some dynamic sound placing out of it, but I'm astonished by how easily I can distinguish all the different instruments in a song. I've never experienced such deep bass, it's amazing.
I wish the cable Sennheiser gave would be a bit easier to twist and that the connector is sometimes loose in the left ear. Otherwise it's a really solid package. Really recommend it to anyone who wants to get a great IEM.
IE600 are very small and fit so well and comfortably in the ears.
IE600 are very balanced, I really like the way they were tuning. Be aware that connected directly to a phone, the IE600 will not sound to their best, they need a somehow more powerful source than the your phone.
I used them connect to the Chord Mojo and Ifi Go Blu (balanced), and although the IE600 sound different on both, they sound really good.
