Enjoy the true sound of music with the Sennheiser IE 900. This IEM features 7mm TrueResponse drivers with the new XR3 technology for brilliant treble, powerful lows and clear mids. The high-quality build is designed to last and fit comfortably.

Hear Every Detail
Experience the finest nuance in your music with the Sennheiser IE 900. And, it’s not just the tonality of each instrument that is clearly audible, but also the acoustic properties of the room. Immerse yourself in a vast soundstage without any distracting peaks or troughs. An acoustic back volume – a small chamber within another chamber – is used to manage the slope and amplitude of the bass lift. It controls the overall volume and direction of the air as it moves through the driver unit. The end result: Disciplined bass with uncoloured mids.

Built for Brilliance
With the IE 900, Sennheiser has left no stone unturned. The German designed and engineered 7mm TrueResponse transducers offer brilliant treble, powerful lows and clear mids. The drivers are well-tuned to avoid sibilance and overpowering any one frequency. The warmth only adds that much-needed life to your music. The combination of a variety of acoustic materials in the diaphragm ensures a precise transient response and detailed audio experience.

Designed for Pure Sound
The new XR3 technology uses a system of 3 Helmholtz resonators. These are milled right into the solid aluminium housing. The tiny channels in this system prevent resonance peaks that colour the sound. A vortex structure in the nozzle swirls acoustic energy in the frequency bands to smoothen unwanted peaks. Together, these high-end technologies deliver incredible balance and transparency to your music.

Precise Build for Precise Sound
The Sennheiser IE 900 does not shy away from making a statement with its high-class housings. Each one has been cut from a single block of aluminium using 5-axis CNC machined precision. This enhances the electro-acoustic components of the IEM. Once anodized, it is highly resistant to wear and corrosion. The end result? A work of pure art.

IEMs that Fit Seamlessly
Working musicians require IEMs that fit well. And, we took inspiration from this and translated it into IE 900’s form factor. Silicone ear adapters and elastic foam ear adapter sets in three different sizes adapt to the natural shape of your ear for a tailored fit. It does away with uncomfortable sibilance or resonance, letting you enjoy your music just the way the artist intended.

The Perfect Connection
Apart from its sonic properties, a great IEM also offers unmatched durability and reliability. The recessed, 4.8mm-wide MMCX sockets ensure outstanding strain relief. The para-aramid reinforced cable is rated for thousands of bend cycles and terminate with gold-plated Fidelity + MMCX cable connectors on one end and a 3.5mm stereo plug on the other. For audio lovers looking to plug their IEMs into hi-fi audio devices, the IE 900 also comes with symmetrical 2.5mm and 4.4mm cables. The serialised case keeps it safe when on the go.
