Sennheiser designed the IE 900 with excellence in mind. Their goal was simple: to create a pair of in-ear monitors perfect for listening to music in any environment. Designed to give you the same performance and comfort that pros experience, the IE 900 offer a single-driver response that delivers a flawless, uncolored performance from 5 Hz to 48 kHz.
No stone is left unturned, from the resonant chambers to reduce frequency build-up, to the thought and care put into each set of accompanying eartips. Cables are included for conventional 3.5mm devices, but you'll also find 4.4mm and 2.5mm balanced jacks for hi-fi equipment. A case, cable clip, cleaning tool, and cloth are also included.
What you hear is a pleasantly disciplined bass and mid-range experience. Unpleasant resonances and listening fatigue vanish in this small space with a big effect.
The X3R is milled right into the solid aluminum housing of each earphone. Tiny channels eliminate resonance peaks, which, in less advanced products, would color the sound signature and alter the feel of your music. In addition, Sennheiser has fashioned a complex Vortex structure into the nozzle of each earphone. This swirls acoustic energy in problematic frequency bands to smooth out peaks.
The cables themselves are para-aramid reinforced to withstand many thousands of bend cycles. Connect to practically any digital audio source with the 3.5mm stereo plug including headphone amps, laptops, and audio interfaces. Each pair of IE 900s also includes symmetrical 2.5mm and 4.4mm cables for plugging directly into hi-fi components with balanced outputs.
Now you can enjoy a fit and quality that rival what artists who create your music experience. Included with the IE 900 are silicone ear adapters and three elastic foam ear adapter sets in three different sizes. They adapt to the natural shape of your ear for a tailored fit.
