A new level of clarity

A single dynamic driver only — of the highest quality, of course. In developing the IE 900, we faced a fundamental choice. The inherent compromises multi-driver systems require (phase issues and the resulting distortion in overlapping frequency bands) made the decision easy. There would be a single dynamic driver only — of the highest quality, of course.

To get exactly the sound we were looking for, we designed a sophisticated system of three Helmholtz resonators — a crucial element in the X3R technology - milled right into the solid Aluminium housing of each earphone. These tiny channels eliminate resonance peaks which can colour the sound signature and alter the feel of your music. In addition, a complex structure in the nozzle of each earphone — the Vortex — swirls acoustic energy in these frequency bands to smooth out peaks.

The sound of manufacturing expertise

We build the IE 900 at our state-of-the-art audiophile manufacturing plant in Ireland. It's the same facility that builds the revered HD 800S, HD 820, HD 650 and HD 600.

The use of Aluminium was a clear choice: well-suited to high-precision milling, it also provides an aesthetically pleasing, long-lasting home for the electro-acoustic components. A five-axis CNC machine precision cuts each housing individually from a single block of Aluminium. The result is truly a work of art. Once anodised, the housing is highly resistant to wear and corrosion — music to the ears of any daily listener. The drivers in each pair of IE 900s are matched during our automated manufacturing process to practically eliminate variance. The result? A transparent soundstage with no gaps or holes.

An acoustic back-volume establishes balance

To ensure accuracy across this critical frequency band, we’ve employed what is known as an acoustic back volume. Our goal was to achieve a transparent sound with no distracting peaks or troughs. One thing this requires is clear separation of lows and mids.

To ensure accuracy across this critical frequency band, we’ve employed what is known as an acoustic back volume. It’s a small chamber within a chamber we have tuned to manage the slope and amplitude of the bass lift. The way the back volume helps achieve such a clear and natural sound signature is by controlling the direction and overall volume of air as it moves through the transducer system. What you hear is a pleasantly disciplined bass and mid-range experience. Unpleasant resonances and listening fatigue vanish in this small space with a big effect.
