Every detail matters, new Sennheiser IE900 headphones.

The new flagship Sennheiser IE 900 audiophile headphones set a new benchmark for portable audio fidelity.

With the new audiophile IE 900 headphones, Sennheiser has brought technological innovation, meticulous attention to detail and an unwavering demand for perfection to deliver a hassle-free listening experience. Manufactured in the audio specialists’ offices in Germany, every aspect of the in-ear headphones has been designed to work in harmony to achieve the desired acoustic tuning and to reduce resonances and masking effects. The new IE 900s feature Sennheiser’s patented This ensures bright, natural high-end sound reproduction and reveals even the finest details in the music.

Sennheiser’s quest to deliver the highest fidelity sound begins with the IE 900 housings. They are milled from a single block of aluminum to create the headphones’ unique Triple Chamber Absorption System (T3CA). Originally developed for the IE 800, the IE 900 features the next generation of the patented absorption system, which uses three chambers and an acoustic vortex milled into the mouthpiece to counteract the masking effect. This acoustic phenomenon is accentuated when humans cannot perceive high frequencies at low volumes if louder sounds are produced at the same time in a lower frequency range. By removing energy from masking resonances, the absorption system prevents unwanted peaks, making even the subtlest nuances of sound audible.

‘No detail is too small when you strive to set a new benchmark in portable audio fidelity. We have designed all the components of the IE 900 to work together to deliver extraordinary audio performance,’ said Jermo Köhnke, Product Manager at Sennheiser. ‘Whether long listening sessions at home or on the go, listeners will never have to compromise on their musical experience.’

Sonic Experience and Manufacturing Precision

Compared to traditional multi-driver concepts, single-driver technology promises higher fidelity for listeners. That’s why the IE 900 features Sennheiser’s new

The IE 900 transducer is combined with the rear acoustic volume in the fully automated transducer manufacturing facility – at the audio specialist’s headquarters in Germany – resulting in the lowest unit-to-unit variations in miniature dynamic drivers .

A dedicated team in Wedemark, Germany designs, manages and manufactures the IE 900 to the highest production standards in the audio industry. Their exclusive housings are precision milled from a high-performance aluminum alloy to maintain their pristine presence over the years. During production, transducer components are closely examined with precision cameras, and completed transducers are tested before and after pairing. For optimal performance, the assembled left and right earbuds are hand-paired for conjunction.

Extremely light and flexible, the broadband transducers prevent distortion, deliver a natural, balanced sound and ensure audio transparency, regardless of listening volume. A newly developed membranous sheet provides a high degree of internal damping, ensuring minimized natural distortion and resonances (THD: 0.05% at 94 dB, 1 kHz). With a frequency response of 5 Hz – 48,000 Hz, the IE 900 reveals even the finest details in music.

Supreme/Superior Convenience and Comfort

Thanks to the high-performance MMCX Fidelity Plus connector, audiophiles have the freedom of cable choice with the IE 900. Deeper integration into the housing provides better stability for the gold-plated/plated connector. The headphones come with an unbalanced cable with a 3.5mm jack and balanced cables with 2.5mm and 4.4mm jacks. Tested and improved for robustness and longevity, para-aramid reinforced cables can withstand thousands of bending cycles. For a comfortable and secure fit, the IE 900s offer ergonomic features such as individually adjustable ear hooks, as well as silicone and memory foam ear tips in three sizes, perfect for extended periods of personal music enjoyment.

The Sennheiser IE 900 will be available starting in June for €1,299 (MSRP).
