Sennheiser IE 900

Introducing the new flagship IE 900 earphone from Sennheiser. Sennheiser headphones have long appealed for audiophiles, and their earphones can compete with the best of them. Replacing the IE 800S, the IE 900 embodies the peak of German audio engineering and manufacturing. 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. From the optimized 7mm transducers and innovative X3R resonator chamber technology to the precision-manufactured aluminum housing — every facet of the IE 900 is engineered to deliver the most pure, natural, and excellent sound that is brimming with detail. In fact, "every detail matters" was a guiding principle in the creation of the IE 900.
