Dieser außergewöhnliche Ohrhörer reproduziert nicht nur die Details und Emotionen einer Aufnahme – er verstärkt sie. Denn jeder IE 600 ist ein Meisterwerk. Vom handveredelten Gehäuse aus amorphem Metall bis zu den von Sennheiser entwickelten und gefertigten High-End-Audiokomponenten ist jedes Detail dieses Ohrhörers auf höchstem Niveau durchdacht und mit größter Sorgfalt gefertigt. Der ausgewogene Frequenzgang des IE 600 verspricht eine unverfälschte, natürliche Wiedergabe – und aufgrund der hochwertigen Materialien vermag er dieses Versprechen auch noch nach vielen Jahren einzulösen.


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.

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.

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 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 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.

IE600 perfection

Heard a lot of good things about this IEM and decided to try it. I am serious IEM enthusias & for reference I love EJ07 ++ UM Mest mk2. I believe hearing IE600 I released non of reviews are doing this IEM real justice how good they realy are. They can be right of the bat your only IEM and game over. No more search for wholly grail. It's there in my hands under name IE600. I am buying this days one more set as a backup and unsubscribing from all this audiofil youtube chanels. IE600 all you ever need on the reach of alsmost everyone hand.

Great IEM but something is missing

These were the earbuds I have wanted for a long time and I finally took the plunge and picked them up. In short, they sound amazing, especially if you use the 4.4 termination, but I am surprised at the ear tips and how they do not fit my ears well. I communicated with Sennheiser about this and how they hurt my left and I was told to try other tips (of course I tried all the tips!) I used my earbuds from Moondrop, which are a good fit until I find something better.

It may just be me but I am not in love with the tips provided and I would expect better from a $1000 IEM.

Awesome earphones

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

Love IE600

Great sound!!!

Almost returned... but it grew on me.

I have to say, when I first put on the headphones I expected them to blow my socks off. Coming from HD598s - considerably less noteworthy headphones - I was offended by the almost tinny sound of the IE 600s. But after a day or two I was able to adjust to the sound (but still not quite fully). There are definitely some tracks that play very nicely with the IE 600s, namely vocals and real instruments. Sadly, most of my music is electronic music that seems to be mixed too harshly in the high end for listening with the IE 600s.

The fit is decent, it did hurt my ears slightly as I got used to wearing them (even after finding the best fitting tip), but that seems to subsided slightly. I find doing voice calls with the IE 600s very difficult because my own voice reverberates through my ears in a jarring way.

The build quality is good, the earbuds themselves are well designed and I like the look and feel. I wish the wires that come in the box, however, were some kind of threaded wire for durability and tangle prevention. It's just something I'd hope for at this price tag.

The carrying case looks good but the inner design could probably have some more compartments for keeping the buds and wires separate and secure, and perhaps a sleeve for the cleaning tool. I also have a problem with the zipper, it came in a state where it often gets stuck. I think a slightly looser fit for the case would help the zipping process without sacrificing integrity.

Overall, I enjoy listening to music with the IE 600s, but I wish they had really blown me away. I nearly returned them to get the IE 300s because I guess the 300 model would give me enough to make me happy without blowing me away, which is what I got with the 600 model except at a much steeper price.

At the end of the day, I admit I'm a loyal Sennheiser customer. As long as I can rely on the build quality and trust that I'm getting what I pay for in terms of a listening experience, I will always buy a Sennheiser product when I have the choice. On that note, I will be buying one of your high end open back, over-ear models at some point in the next year or two... Is this the time where I ask for some sort of discount? Haha, just joking - but please do keep up the good work and I hope my feedback helps the team in some way. Cheers!
