Introducing the IE 900, which harmonizes all the craftsmanship and engineering you have. With no compromises in the pursuit of perfect sound quality and attention to detail in design, engineering and quality control, the high-end IE 900 is the new flagship of next-generation portable hi-fi audio.

Rich and elegant sound quality

Reproduces an elegant and neutral sound with a crystal-like transparency in all frequency bands, from responsive low frequencies to delicate high frequencies. Further evolution of the flagship: IE 900 delivers richness and clear sound quality, especially in the high frequencies. Especially in the high range of 4kHz and 10kHz or more, it has evolved further from the popular model IE 800S, and it has a more natural and clear sound without distortion. Bringing unwavering “sound” to a higher level

The sound and elaborate design of craftsmanship

In order to achieve high-end sound, we have combined outstanding acoustic technology, engineering, design, materials, and quality control to a high standard and sublimated it brilliantly.

A new innovation called X3R technology

The high-performance single dynamic driver produced by Sennheiser, one of the world’s leading in-house developed drivers, has good left-right phase, high connection in all bands, presence of low-frequency volume, sound omission, and high-frequency reproduction. It has excellent properties, all of which are due to its outstanding technology. Sennheiser’s new flagship True Response transducer, three resonator chambers and new X3R technology with acoustic vortex provide an innovative listening experience. It is a technology packed with top-level acoustic technology, which is possible because of consistent in-house development and manufacturing.

Elaborate design

A high quality housing made from machined aluminum blocks with strict tolerance standards. This housing is an important skeleton of X3R technology that brings new innovations. In addition, it is designed with a material that can be used for a long time without deteriorating even after a long period of time. Thorough quality control that manually matches the left and right earphones and performs repeated tests to provide the maximum listening experience.

Newly developed triple resonator chamber acoustic vortex

The housing is made from a finely machined aluminum block that does not shift in size, and is equipped with three resonator chambers and an acoustic vortex. Each chamber improves the response of each constant frequency band to reduce masking and distortion. And create a sound that spreads naturally with acoustic vortex.

Fidelity Plus MMCX connector and durable cable

Gold-plated Fidelity Plus MMCX connectors are used to ensure stability, durability and a higher quality sound experience. Furthermore, the cable is made of a special material (para-aramid) and has high durability that can withstand thousands of bends. * Since the peripheral part of the terminal has a unique shape, compatibility with cables made by other companies has not been confirmed.
