The IE 900 — goodbye to tradeoffs

The IE 900 reveals the true potential of any recording. If it’s a masterpiece, you’ll hear it. Brilliant, sparkling treble — with no trace of sibilance.

High-fidelity recordings are pieces of art. Just as with a valuable painting, it would be a disgrace to allow damage during transport. The IE 900 reveals the true potential of any recording. If it’s a masterpiece, you’ll hear it. Brilliant, sparkling treble — with no trace of sibilance. Powerful lows without creating muddy mids. An uncanny ability to resolve fine detail — alongside warmth and comfort for extended sessions. All these qualities derive from inspired feats of engineering. Take Meier & Wolff ’s trusted 7 mm transducer, for instance. We’ve made it just that much better for the IE 900. Or the all-new X3R triple-chamber absorber technology milled right into the solid aluminium core with its downstream acoustic vortex. Taken together, these innovations deliver a unique level of balance and transparency — so you never have to compromise again.

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 aluminum housing of each earphone. These tiny channels eliminate resonance peaks which can color 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.
