SENNHEISER / 508949

The IE900 is a high-end wired in-ear earphone that incorporates SENNHEISER's attention to detail in every aspect of quality, including design and acoustic technology. It is the new flagship earphone for the next generation of portable HiFi audio.

*From 2022, the design of the carrying case will be changed sequentially. *Please note that we cannot accept requests for new or old designs. Features: ■Rich and elegant sound quality - From responsive low frequencies to delicate high frequency depiction, it reproduces elegant and neutral sound with crystal-like transparency in all frequency bands. ■Further evolution of the flagship - In terms of high frequencies, the IE 900 achieves rich and clear sound quality. In particular, in the high frequencies above 4kHz and 10kHz, it has evolved further from the popular model IE800S, providing a more natural and clear sound without distortion. ■Sound woven with craftsmanship and exquisite design - To achieve high-end sound, it combines outstanding acoustic technology, engineering, design, materials and quality control at a high level. ■A new innovation called X3R technology - Equipped with a high-performance single dynamic driver produced by Sennheiser, one of the world's leading in-house developers. It excels in terms of good left-right phase, high connection across all frequency bands, a rich low-frequency presence, a sense of sound clarity, and high reproduction of high frequencies, all of which are the result of outstanding technology. - The new X3R technology, equipped with Sennheiser's new flagship TrueResponse transducer, three resonator chambers, and an acoustic vortex, delivers an innovative listening experience. This technology is packed with top-level acoustic technology, and is made possible only through consistent in-house development and manufacturing. - Newly developed triple resonator chamber and acoustic vortex - The housing, made from a precisely machined aluminum block with no deviations, is equipped with three resonator chambers and an acoustic vortex. Each chamber improves the response of a certain frequency band, reducing masking and distortion. The acoustic vortex creates a naturally expanding sound. - The triple resonator chamber version suppresses peaks in the 6.5k to 10kHz frequency band, reproducing smooth, comfortable high frequencies. ■Membrane foil (diaphragm) and redesigned voice coil - The polished membrane foil pursues high internal loss and minimizes naturally occurring unnecessary resonance and distortion (THD: 0.05% 94dB, 1kHz), providing a stable sound quality experience worthy of the flagship TrueResponse transducer. - The newly redesigned voice coil improves the performance of the magnet system, bringing out a natural and clear sound in the high range. - Evolved from IE800S - The IE900 has evolved significantly from the popular IE800S. Compared to the IE800S, the IE900 has a lifted midrange and smoothed the high range. For example, you can feel the high sound quality from the first stroke of a violin. - Fidelity Plus MMCX connector and durable cable - To ensure stability, durability, and a higher quality sound experience, the connector uses a gold-plated Fidelity Plus MMCX connector. Furthermore, the cable is made of a special material (para-aramid) that makes it highly durable and able to withstand thousands of bends. (*Due to the unique shape of the area around the terminals, compatibility with cables from other manufacturers has not been confirmed.) ■Weight: Approximately 4g (weight of one side, excluding cable) ■Type: Dynamic, in-ear type ■Cable length: 125cm, Y-type ■Earphone terminal: MMCX connector (SENNHEISER unique shape) ■Plug shape: 3.5mm stereo mini plug (L-type), 4.4mm (balanced), 2.5mm (balanced) ■Impedance: 16Ω ■Frequency response: 5-48,000Hz (-10dB) ■Sensitivity: 123dB (1kHz, 1Vrms) ■THD: <0.05% (94dB, 1kHz) ■Accessories: Ear adapter set (standard silicone S/M/L, foam S/M/L), cable clip, premium carrying case with serial number, cleaning tool, cloth
