Sennheiser IE 900 – The new flagship

Technical innovations, a love of detail and an uncompromising demand for perfection, all these are cited by Sennheiser electronic GmbH & Co. KG cites all of this as characteristics of the new Sennheiser IE 900 in-ear headphones.

Sennheiser IE 900, this new in-ear headphone is given the task of placing itself at the top of the product portfolio of the specialist Sennheiser electronic GmbH & Co. KG. It is intended to be the new flagship in its segment and to satisfy even the highest demands of audiophile music lovers.

This is not an easy task, as there have long been numerous models in the in-ear headphone segment that are advertised as audiophile solutions and are thus supposed to guarantee music enjoyment of the highest quality even when on the move.

Sennheiser IE 900 – Sets new standards

That’s why the German company has set itself particularly high goals for the new Sennheiser IE 900, which it is convinced will set new standards and deliver nothing less than first-class sound on the move.

Technical innovations, the attention to detail of the developers, uncompromising quality in the features, all this should guarantee a unique listening experience.

Sennheiser X3R transducer

The heart of the new Sennheiser IE 900 is its unique dynamic transducer, the so-called Sennheiser X3R transducer, a further development of the audiophile 7 mm extra-wideband transducer of previous models. Once again, the focus is on even tighter tolerances and expert tuning. In combination with a coupled acoustic rear volume, this driver is said to be superior even to conventional multi-driver concepts, Sennheiser electronic GmbH & Co. KG is convinced.

This driver is manufactured in a fully automated production line at the audio specialist’s headquarters in Germany, so that only minimal scattering occurs throughout the series and thus a consistently high quality is guaranteed.

According to the manufacturer, the extremely light broadband transducers prevent distortion, deliver a natural, balanced sound and ensure transparent reproduction regardless of the listening volume.

Incidentally, a newly developed membrane foil is used here. This ensures a high degree of internal damping and thus minimises natural resonance and distortion. The company gives a THD of 0.05 % at 94 dB and 1 kHz as a reference. Incidentally, with a frequency response of 5 Hz up to 48 kHz, the new in-ear headphones are of course ideally suited for content in hi-res audio and, Sennheiser electronic GmbH & Co.KG is convinced, will reveal even the finest details of the music.

Housing milled from a single block of aluminium

The housing of the new Sennheiser IE 900 is also to be produced according to these high manufacturing standards, namely from a single block of aluminium. In concrete terms, a high-performance aluminium alloy is used, so that a flawless appearance is guaranteed even over many years.

The unique three-chamber absorber system, which Sennheiser calls the T3CA, is milled from this with the highest precision. This system was originally developed for the Sennheiser IE 800 and is also used in the new model.

T3CA three-chamber absorber system

Three acoustic chambers and an acoustic vortex milled into the receiver output counteract the so-called masking effect. This acoustic phenomenon occurs because the human ear cannot perceive high-frequency sounds at low volume levels when louder sounds occur simultaneously in a lower frequency range. By removing the energy of these masking resonances, the absorber system prevents unwanted peaks and makes even the finest nuances of sound audible.

Precision cameras closely inspect the transducer components during production, and the finished transducers are tested before and after assembly. For optimal performance, the assembled left and right earphones are paired by hand.

Cable flexibility through MMCX

By using MMCX connectors, the Sennheiser IE 900 is designed to give music lovers the freedom of choice when it comes to cables. The deeper integration into the housing ensures better stability of the gold-plated plug. The earphones come with an unbalanced cable with a 3.5 mm mini-jack plug as well as balanced cables with 2.5 mm as well as 4.4 mm plugs.

Tested for robustness and durability, the improved cables with para-aramid reinforcement can withstand thousands of bending cycles, according to the manufacturer. For a comfortable and secure fit, the Sennheiser IE 900 offers ergonomic features including individually adjustable earpieces and silicone and memory foam ear cushions in three sizes.

“No detail is too small when you want to set new standards in portable audio reproduction. We’ve designed all the components of the IE 900 to work together to deliver exceptional audio performance. Whether for long listening sessions at home or on the road, listeners shouldn’t compromise on their music experience.”
