Sennheiser IE 600 In-Ear Headphones

Sennheiser IE 600 Overview

Experience flawless, unadulterated, and clear sound reproduction with the Sennheiser IE 600 In-Ear Headphones, perfect for listening to music in any environment. Built on Sennheiser’s groundbreaking TrueResponse technology with handpicked and matched, dynamic 7mm single drivers, the earphones are optimized to achieve the lowest possible distortion, while delivering an extra-wide frequency response from 4 Hz to 46.5 kHz. Dual-resonator chambers (D2CA) make the subtlest nuances of your sound audible by eliminating masking resonance, giving you an exquisitely neutral acoustic voicing with powerful, yet fast and accurate low-end response that bring you closer to your music. The drivers are enclosed in ZR01 amorphous zirconium housings, which ensure enhanced resilience and lasting great looks thanks to the glass-like atomic structure of amorphous metal. Cables are included for conventional 3.5mm devices, but you’ll also find a 4.4mm balanced jack for hi-fi equipment. The IE600 are designed and engineered in Germany and made in Sennheiser’s Audiophile Production facility in Ireland.

Stronger than Steel, Built to Last

• The IE600 employs zirconium alloy from Heraeus Amloy Technologies, which offers 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 housings are 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.

Balanced, Neutral Voicing
To achieve a natural sound reminiscent of the neutrality provided by high-end studio monitors, Sennheiser’s 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. Each earphone also integrates Dual 2 Chamber Absorbers (D2CA), which capture and attenuate masking frequencies for maximum presence and clarity.

• Automated Manufacturing, Handcrafted Finish
• Production of the amorphous metal housing takes place in Germany and includes both automated and manual steps. A computer-controlled laser sinters a thin coat of metal powder, welding the molten alloy to the already hardened material beneath it. Layer by layer, the part builds up to its ultimate shape. A technician then removes any artifacts of the manufacturing process by hand.

• After thorough cleaning, steel shot blasting, polishing, and sophisticated surface treatment, the housing assumes its final, extremely durable aesthetic. Even daily use leaves practically no evidence in the form of scratches or wear.
