Product Description

L'IE 900 de Sennheiser établit une nouvelle référence en matière de fidélité audio portable grâce à l'innovation technique (X3R), à une attention méticuleuse aux détails et à une exigence de perfection sans compromis. Chaque aspect de l'IE 900 a été conçu pour fonctionner en harmonie afin d'obtenir l'accord acoustique souhaité et de réduire les résonances et les effets de masquage. Sa conception acoustique assure une reproduction brillante et naturelle du son haut de gamme et révèle les moindres détails de la musique.

Développé en Allemagne et fabriqué dans notre usine ultramoderne en Irlande

Les transducteurs sont appariés pendant le processus de fabrication afin d'éliminer pratiquement toute variance.

Le boîtier monobloc est usiné avec précision à partir d'un seul bloc d'aluminium.

Assemblage à la main par une équipe de spécialistes au siège de Sennheiser, avec des tolérances très fines.

Une sélection d'adaptateurs d'oreille en silicone et en mousse assure un ajustement optimal pour une isolation sonore élevée.

Les crochets d'oreille réglables s'adaptent à la forme naturelle de l'oreille pour un ajustement sur mesure.

Les câbles renforcés en para-aramide et les connecteurs plaqués or Fidelity+ MMCX garantissent la longévité de l'utilisation.

Un choix de câbles symétriques et asymétriques (2,5 mm/3,5 mm/4,4 mm) pour une connectivité facile.

Garantie mondiale de 2 ans

Explore every last detail

Considerable effort goes into capturing the finest nuances of a musical performance. Re-living the creativity and texture recorded in the studio or concert hall can be a source of great pleasure. But only if the listener’s playback equipment allows. Our German-engineered and manufactured TrueResponse driver ensures exceptionally natural reproduction. A large part of its very precise transient response comes from the unique combination of materials in the diaphragm together with its high inner dampening. So when the signal stops, the sound stops too. This is how the IE 900 can reveal details in tracks you thought you knew inside out.

But the only thing that counts is what you, the listener, hear. The tonality of each instrument becomes clearly audible. And it’s not just the skills of the musicians that the IE 900 reveals. Even the acoustic properties of the room gain a new presence. Instead of remaining on the surface, you can now dive deep into complex passages — all while immersed in a breathtaking sound stage.

A new level of clarity

In developing the IE 900, we faced a fundamental choice. The inherent compromises multi-driver systems require (phase issues and the resulting distortion in overlapping frequency bands) made the decision easy. There would be a single dynamic driver only — of the highest quality, of course.

To get exactly the sound we were looking for, we designed a sophisticated system of three Helmholtz resonators — the X3R. It’s milled right into the solid aluminum housing of each earphone. These tiny channels eliminate resonance peaks which, in less advanced products, can color the sound signature and alter the feel of your music. In addition, a complex structure in the nozzle of each earphone — the Vortex — swirls acoustic energy in these frequency bands to smooth out peaks.

An acoustic back-volume establishes balance

Our goal was to achieve a transparent sound with no distracting peaks or troughs. One thing this requires is clear separation of lows and mids. To ensure accuracy across this critical frequency band, we’ve employed what is known as an acoustic back volume. It’s a small chamber within a chamber we have tuned to manage the slope and amplitude of the base lift. The way the back volume helps achieve such a clear and natural sound signature is by controlling the direction and overall volume of air as it moves through the transducer system. What you hear is a pleasantly disciplined bass and mid-range experience. Unpleasant resonances and listening fatigue vanish in this small space with a big effect.

The sound of manufacturing expertise

We build the IE 900 exclusively at our famed German manufacturing facility. It’s the source of the outstanding quality Sennheiser products are known for the world over. Aluminum was the material of choice for this application. Well-suited to high-precision milling, it also provides an aesthetically pleasing, long-lasting home for electro-acoustic components. A five-axis CNC machine precision cuts each housing individually from a single block of aluminum. The result is truly a work of art. Once anodized, the housing is highly resistant to wear and corrosion — music to the ears of any daily listener. The drivers in each pair of IE 900s are matched during our automated manufacturing process to practically eliminate variance. The result? A transparent soundstage with no gaps or holes.

A precise fit for precise sound

Working musicians rely on high-quality, form fitting earphones known as personal monitoring systems. But we felt the privilege of enjoying perfect live sound should not be the exclusive right of the performers of the world. So, we took the comfort and secure fit of these professional solutions as inspiration for the IE 900. Now you can enjoy a fit and quality that rival that experienced by the artists who create your music. Included with the IE 900 are silicone ear adapters and three elastic foam ear adapter sets in three different sizes. They adapt to the natural shape of your ear for a tailored fit. We’ve all been there: an amazing piece of music spoiled by a recurring bass note that happens to match the resonant frequency of your loudspeakers or headphones. Or rough treble sibilance that makes longer sessions uncomfortable. Such obvious deficiencies are unthinkable with the IE 900. All you will hear is precisely what the artist intended. They’re perfect at your desk, on a train, or taking a walk through the woods. Never have a listening session spoiled by your earphones again.

Single Driver's Undeniably success

One of the best single dynamic drivers in the market. I've been using a lot of other multi-driver unit including hybrid and BA and ES. IE900, after being an IE800s and IE800 user, has taught me again that the level of "completeness" and the "seamless" transition between highs and lows prooves the unshaken place of single dynamic driver IEM's. IE900 has again improved from the IE800s, bringing the lows even more accurate while increasing the clarity of the mids and highs again. Fantastic product.


Very detaieled natural sound in a different league to mass market ear buds


These are lovely jewel-like earphones and very comfortable to wear. They reward a good music source and the whole experience of listening to muic in this way is truly immersive.

IE 900 + TIDAL

IE 900 Great
Don't know about TIDAL, I've got to wait a month
