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 Sennheiser’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 aluminum 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.
