Sennheiser IE 600 In-Ear Headphones Deliver Neutral Sound Reminiscent of High-End Studio Monitors
Simply beautiful sound, and the lengths Sennheiser will go to achieve it — that is the story of the IE 600 in a nutshell. These in-ear devices not only reproduce the detail and emotion of a recording, they transcend it. From the hand-finished amorphous metal housing to high-end audio components developed and made by Sennheiser, everything is manufactured to the strictest tolerances. The balanced frequency response and extremely durable materials have been engineered to provide clear, natural voicing and a unique aesthetic that will retain its good looks for decades.
To achieve a natural sound reminiscent of the neutrality provided by high-end studio monitors, Sennheiser engineers carefully tuned the acoustic back volume inside the nozzle of the IE 600. This voicing lends a presence and intimacy that brings listeners closer to the music, allowing them to discover new accents and details. However, arriving at this level of poise and naturalness was not without challenges. When similar sounds occur in a track simultaneously, for instance, it can become difficult for the human ear to resolve all the nuances. The IE 600 integrates dual two chamber absorbers (D2CA) which capture and attenuate these masking frequencies, revealing even the finest textures of your music.
Researchers have worked for many years to perfect amorphous metals for manufacturing. The wait was worth it — the zirconium alloy from Heraeus Amloy Technologies we chose for the IE 600 has triple the hardness and flexural strength of high-performance steel. Shock-frozen during manufacturing, amorphous metals never have a chance to form a crystalline structure like conventional metals. The result is a lustrous, satiny surface that is extraordinary resistant against corrosion and scratches.
The IE 600 housing is fabricated using metal-powder-based 3D printing that can create any shape imaginable within tight tolerances. Chambers and channels form as part of this additive manufacturing process with no milling required. However, cost does limit the potential applications of this new material. One of the only places you'll find it — besides ultra-high-end products like the IE 600 — is in the drilling head of a NASA Mars Rover, where extraordinary resilience in extreme conditions is required.
“The sound of the Sennheiser IE600 is absolutely saturated in detail — it drips from every element of the recording.”
