Product Description

Sennheiser IE 900 In-Ear Headphones

Every Detail Matters.
The new IE 900 from Sennheiser sets a new benchmark in portable audio fidelity through technical innovation (X3R technology), meticu- lous attention to detail, and an uncompromising demand for perfection.
Every aspect of the IE 900 has been engineered to work in harmony to achieve the desired acoustic tuning and to reduce resonances and masking effects. Its acoustic design ensures brilliant, natural high-end sound reproduction and reveals even the finest details in the music.

Features

Introducing the X3R Technology
Innovative X3R technology, unique to the IE 900, unites the German-made 7mm TrueResponse transducer with specially developed membrane foil, triple-chamber absorber system and acoustic vortex for an intense listening experience.

What refines the X3R technology is its three Helmholtz resonator chambers and acoustic vortex which smoothens masking resonance. The three resonator chambers are precision-drilled into the elegant aluminium chassis of the IE 900 and placed between the diaphragm and the nozzle.

This complete harmony of systems is at work to unlock the de- tails buried within every track.

German-made 7mm TrueResponse Transducer provides extra wide frequency extension and ultra-low distortion for exceptionally natural sound.

The drivers in each pair of IE 900s are matched during our automated transducer manufacturing process to practically eliminate variance.

The specially developed membrane foil used in the transducer diaphragm delivers rapid response times for pristine, clear audio across the entire frequency spectrum, even at atypical volume levels.

The triple-chamber absorb- er is a sophisticated system of three Helmholtz resonators milled into the solid aluminium housing.

These tiny channels eliminate resonance peaks which can colour the sound signature and alter the feel of your music.

Milled directly into the nozzle, the acoustic vortex is a complex structure which swirls acoustic energy in these frequency bands to smooth out peaks.

Ultimate Precision & Craftsmanship
Designed, engineered, and made in Germany the one-piece housing is precision-milled from a single block of aluminium on an avant-garde 5-axis-CNC machine.

The demanding milling process takes 40 minutes for each pair of IE 900. Components are hand-assembled by a specialist team at Sennheiser s headquarters with meticulous attention to detail.

Air Control
An acoustic back volume controls the direction and overall volume of air as it moves through the transducer system, so you hear a pleasantly disciplined bass and mid-range without distracting peaks or troughs.

An airflow inlet allows for air movement to ensure air is not trapped inside the housing. Trapped air would act like a spring and reduce bass performance.

A precise fit for precise sound
The secure form fitting lightweight high-strength anodised aluminium housing offers exceptional resistance and long-lasting aesthetic beauty.

Adjustable flexible ear hooks and a selection of silicone and memory foam ear adaptors in 3 sizes (S/M/L) adapt to the natural shape of your ear for a tailored fit and high noise isolation.

It pays to have good connections
A choice of para-aramid reinforced cables (2.5 mm, 3.5 mm, 4.4 mm) with gold-plated Fidelity+ MMCX connectors provides connection to practically any audio source.

The para-aramid reinforced cables can withstand many thou- sands of bend cycles and the special recessed design of the gold-plated Fidelity+ MMCX connectors reduce strain on the connector and ensure reliability even after hundreds of cycles.

Hi-Fi Choice - Recommended

...the IE 900 scours detail from the noise floor like nothing else here. Articulation, separation and drive are equally impressive while treble extension and refinement are simply outstanding.

...greater clarity on a still larger soundstage. And yet it's the way the individual attributes coalesce into a coherent whole that stuns.

...voice has a purity and depth that makes you think you're hearing it for the first time.

Indeed, whatever you play, there's a powerful feeling nothing is being missed - not just how low-level detail, but the finest shades and textures of instrumental timbre, nuances of technique and emotion.

LIKE: Effortless transparency, speed and coherence; size and weight.

WE SAY: A pristine sonic performance that really doesn't miss a thing.

Hi-Fi Choice | | July 2021

It's no mean feat to sound simultaneously wide open and tightly unified, but it's this apparent dichotomy that's the most immediately impressive aspect of the IE 900 sound.

The Sennheisers create such a spacious soundstage that each individual element or strand of the recording is simple to locate, enjoys proper autonomy in its specific area, and has more than enough room to reveal even the finest or most transient details of its individual performance.

...the impression of a group of musicians performing sympathetically, responding to each other and to the demands of the composition on the fly, is extremely strong. Very few headphones, no matter the price, can communicate the idea of musicians all bearing down on a piece of music with a commonality of purpose, but a free-flowing looseness at the same time, as these Sennheisers.

...smooth, even and utterly convinving

Bass is full-figured but fleet of foot, with plenty of substance but next-to-nothing by way of overhang - control is absolute.

Detail levels are sky-high, and the line between forensic meticulousness and spontaneity of performance is walked with complete confidence. Listening to this song as an information-rich digital file via a pair of Sennheiser IE 900 is not unlike looking at a beautiful view through a freshly washed window.

...they are as soothing as they come...they have the dynamic prowess and powers of rhythmic expression...They're light, comfortable...

The way the housings are milled, and the material from which they're constructed, makes them look quite attractive in situ too.

...you'll know exactly why they cost what they cost.

Hi-Fi+ | | July 2021

...effortless coherence across the frequency response...allows for the tonal beauty of the track to be the main focus. Tiny little details are effortlessly picked out of the mix...the scale and impact is possesses...exceptionally fast and controlled-sounding earphone. Bass starts and stops with precision...the IE 900 sounds superbly three dimensional.

This is a staggeringly talented in-ear...this is one of the very finest earphones anywhere near the price.

Staggeringly open, engaging.

A truly outstanding earphone that takes Sennheiser's single-driver ethos another stage further.

Hi-Fi Choice | | June 2021

Big, astonishingly cohesive sound.

I've no problem with acknowledging that £1099 is a lot of money for a wired earphone but for a device that allows you briefly transcend the limitations of space and time... it's not too bad.

Ed Selley | avforums.com | June 2021

Sennheiser’s IE 900 combine listenability, insight and comfort, making them one of the front runners at this elevated price

There’s no denying that the IE 900 are a pricey proposition, but if you have a good enough source and amplification, their build, engineering and sound quality more than justify that hefty outlay.

- Detailed, articulate sound

- Refined yet entertaining presentation

- Clever engineering
