Your Sennheiser IE 900
For the most sophisticated audiophiles, the
search for the ultimate sound is a ceaseless
quest for perfection. Inspired by this passion,
we developed the IE 900, the new flagship of
our in-ear headphone range, which sets new
standards in audio fidelity.
From the exquisite one-piece metal housing,
to an improved version of the acclaimed 7 mm
XWB transducer, to the conductive proper-
ties of the sound channel: Every aspect, no
matter how small, was considered to make our
extensive acoustic know-how audible in these
in-ears. The new acoustic design of the Tru-
eResponse transducers features an enhanced
voice coil, which optimizes performance
at high frequencies for a brilliant, natural
sound reproduction. Natural resonances and
harmonic distortions are minimized by an
optimized membrane foil. The result of the
numerous refinements is an exceptionally
natural sound reproduction to satisfy even the
most discerning audio enthusiast.
Developed in Germany, the IE 900 is manu-
factured to tightest production tolerances.
Final assembly takes place at our factory
specialized in the production of audiophile
headphones in Tullamore, Ireland. Every trans-
ducer is fully tested twice – first individually
and then together after the right and left ear-
phones have been hand-selected in pairs. The
transducers of the right and left earphones

are carefully selected to optimally match with
each other. This passion for detail is also
reflected in the pro-audio inspired premium
design. Each earphone housing is precision-
milled from a single block of high-quality
aluminum to ensure the highest audio quality
while offering exceptional durability.
In addition, the IE 900 provides outstanding
connectivity with Fidelity MMCX connections.

These precise plug connections have been
optimized for mobile use of the earphones.
Due to the high sheathing of the plug connec-
tions, the filigree contacts are well protected
against mechanical stress. On the device side,
a selection of connection cables with 3.5 mm
jack plugs and balanced 2.5 mm/4.4 mm jack
plugs are available.
The ergonomic design includes individu-
ally adjustable ear hooks and a choice of ear
adapters in different sizes for a perfectly se-
cure fit. The cable is made of flexible material
while the cable design allows the cable to fall
naturally and, at the same time, significantly
reduces structure-borne noise compared to
standard cables. Thanks to the outstanding
wearing comfort, the IE 900 is ideal for long
listening sessions of unadulterated music
enjoyment.

Selecting the ear adapters and inserting
the earphones into the ears
The perceived sound quality including bass
performance and the reduction of ambient
noise depends to a large extent on the cor-
rect fit of the earphones in the ears. Figure out
which ear adapter type and size suits you best
in terms of both sound quality and wearing
comfort.
▷ Mount the ear adapters to the earphones
until they lock into place. You can choose
between 2 lock-in positions.

(S, M or L) so that the earphones sit com-

sion of the memory foam.
