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,
Sennheiser developed the IE 900, the new
flagship of their 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
properties of the sound channel: Every aspect,
no matter how small, was considered to make
Sennheiser's extensive acoustic know-how
audible in these in-ears. The new acoustic
design 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.
The IE 900 is manufactured to tightest
production tolerances at Sennheiser's
headquarters in Germany by a specialist team.
Every transducer is fully tested twice – first
individually and then together after the right
and left earphones 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.
The IE 900 also provides outstanding
connectivity with high-quality Fidelity + MMCX
connections and a choice of connection
cables with 3.5 mm and balanced 2.5/4.4mm
jack plugs. The ergonomic design includes
individually adjustable ear hooks and a
choice of ear adapters in different sizes for
a perfectly secure 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.

1. Selecting the ear adapter 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 correct
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.
Silicone
▷ Select ear adapters of the correct size
(S, M or L) so that the earphones sit com-
fortably and securely in your ears.
Visco memory foam
The ear adapters made of Visco foam
adapt optimally to the ear canal due to the
expansion of the memory foam.
▷ Select ear adapters of the correct size
(S, M or L) and roll the ear adapters be-
tween your fingers until they are small.
