Feel closer to the artist! Sennheiser's premium earphone "IE 600" that sticks to materials and acoustic technology

Reproduces everything from sharp low frequencies to sparkling high frequencies with high resolution

Sennheiser has released the IE 600, a wired in-ear earphone. The price is an open price, and the actual price is about 99,880 yen.

Equipped with a TrueResponse transducer developed in-house. It is said that the company's single dynamic driver has realized a smooth connection of sound from low to high frequencies.

Let's quickly check out its main features.

We are particular about materials

Amorphous zirconium material "AMLOY-ZR01" provided by Heraeus in Germany is used for the housing. It's stronger and more stretchy than regular metal, and according to the company, it's extremely rare to use this material for earbud housings due to its ability to withstand temperature changes. a different material).

The same material is resistant to corrosion, so it does not deteriorate easily over time, and it is possible to produce high-end sound over many years. In addition, amorphous zirconium is a material that is used in the drills of NASA's Mars probe, and its durability and robustness can be seen. It can be said that it is also excellent from the viewpoint of protecting the parts inside high-quality earphones.

In addition, the amorphous zirconium material is "heavier" than aluminum and plastic, so it is excellent at blocking out sounds from the outside. For this reason, the company explains that the sound from the earphones can be enjoyed without being affected by the surrounding sounds.

Housing formed with an ultra-high-performance 3D printer

Using an ultra-high-performance 3D printer, the housing is manufactured from the powder state with attention to detail. The housing, which is one of the most important parts of the earphone, was formed using the powder sintering additive manufacturing method, which irradiates a laser with unparalleled accuracy and stacks layers efficiently.

Dual Resonator Chamber for Refining Delicate Sounds

The IE 600's nozzle is equipped with a dual resonator chamber to eliminate resonance caused by masking, which is Sennheiser's special acoustic technology. powered by. This allows the high frequencies to be extended and utilized to reproduce delicate sounds.

This time, by arranging two chambers, unnecessary vibrations are reduced and ear-piercing sounds in specific mid-to-high frequency bands are suppressed. This creates a coherent sound that harmonizes the entire low, mid, and high frequency range.

The IE 600 feels closer to the vocals

The big difference between the IE 600 and the previously released IE 900 is in the 2kHz-3kHz band. The frequency range that rises differs depending on the size of the back volume mechanism installed in each, and as a result, the IE 600 creates a sense of realism with vocals, and is said to be tuned so that you can feel "closeness" to the artist. .

On the other hand, the flagship model IE 900 maintains high reproducibility in all bands. Only two earphones with different colors can be used according to your taste and mood.

Acoustic back volume that produces pure sound with air control

The technology packed into the small world of earphones does not end with just the dual resonator chamber.

Acoustic back volume plays an important role in eliminating unnecessary sounds and delivering clear sound.

This is a mechanism that adjusts the direction and amount of air in the housing to smoothen the sense of separation between low and midrange frequencies, thereby eliminating unnecessary resonance and reducing unpleasant sounds. We will achieve a low and midrange sound with a solid presence that is neutral and does not stagnate.

It's not just the housing that's tough

The IE 600 also uses a gold-plated Fidelity+MMCX connector to support high-quality sound with high durability and stability. The cable is reinforced with para-aramid fiber that can withstand bending over 8,000 times, boasting high durability.
