The IE 900 — goodbye to tradeoffs

High-fidelity recordings are pieces of art. Just as with a
valuable painting, it would be a disgrace to allow damage during transport. The
IE 900 reveals the true potential of any recording. If it’s a masterpiece,
you’ll hear it. Brilliant, sparkling treble — with no trace of sibilance.
Powerful lows without creating muddy mids. An uncanny ability to resolve fine
detail — alongside warmth and comfort for extended sessions.

All these qualities derive from inspired feats of engineering. Take
Sennheiser’s trusted 7 mm transducer, for instance. We’ve made it just that
much better for the IE 900. Or the all-new X3R triple-chamber
absorber technology milled right into the solid aluminum core with its
downstream acoustic vortex. Taken together, these innovations deliver a unique
level of balance and transparency — so you never have to compromise again.

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.

It pays to have good connections

In addition to outstanding sound, audiophiles appreciate
durable products that are made to last. Here as well, the IE 900 excels.

Gold-plated Fidelity+ MMCX connectors ensure perfect contact. Each termination
is seated within a recessed, 4.8 mm-wide socket below the surface of the
housing, providing strain relief. The cables themselves are para-aramid
reinforced to withstand many thousands of bend cycles. But they don’t have to
when protected in the included serialized case.

Connect to practically any digital audio source with the 3.5 mm stereo plug
including headphone amps, laptops, and audio interfaces. Each pair of IE 900s
also includes symmetrical 2.5 mm and 4.4 mm cables for plugging directly into
hi-fi components with balanced outputs. Because when you’re looking for the
most natural and immersive sound, every detail matters.
