Acoustune HS-1790 TI In-Ear Monitor

True Dynamic Sound Reproduction and Spectacle Sound Stage with Speedy Sound Reaction by New Titanium Chamber

The Acoustune HS1790 TI has a CNC milled, ice gray anodized, aluminum housing. As a special design element, a pattern reminiscent of Japanese gardens (Karesansui) was added during the milling process. The patented Myrnix driver sits in a separately CNC milled titanium chamber. The drivers on the HS1790 are made of a patented Myrnix titanium composite material. In addition to the innovative Myrnix film, a dome consisting of titanium film was integrated here.

Sonically, the product impresses with its overwhelming highly sensitive expressiveness, smooth, fresh and with dynamic depth.

A Window to Acoustune

The history of Acoustune

In 2013, several experienced specialists in the Japanese headphone scene came together under the name Acoustune. Their common dream: To realize an exquisite series of in-ear Headphones that combine perfect sound quality, workmanship, and the finest choice of materials. Dynamic full-range drivers are used for the highest possible dynamics and best homogeneity. The manufacturer conducts intensive research and great development effort, investing in transducer technology, material selection and capsule tuning. This brings highest resolution, transparency and silkiness to a level otherwise only known from multi-way models with electrostats.

To achieve this, the acoustically best materials are selected for diaphragms and capsule housings without regard to cost or manufacturing effort: Titanium, beryllium, and the in-house developed miracle material Myrinx are used in various combinations.

Japanese manufacturing art and material science

All models are manufactured with great care in the manufactory in Japan. The highest possible precision is ensured by state-of-the-art machines such as CNC milling machines, which produce the components with incredible accuracy. Final assembly and inspection are always done by hand. The special design combines with the sophisticated mechanical construction and noble materials to create a masterpiece of unique craftsmanship and beauty. In Japan, Acoustune's in-ear models are also known as the "audiophile diamonds among earphones". To achieve an optimal fit of each model to the listener and the source, Acoustune itself develops ear-tips, made of different materials, as well as its own cables.

The special transducer material

Myrinx is based on a high-performance plastic, developed for medical purposes.  This material is also known as "polymer biomaterial" or "biomedical material". In the medical field, these materials have a wide range of applications, such as surgical sutures and implants. The meaning of Myrinx is "eardrum". 

The special properties of Myrnix are:

• The Coherence of the single driver
• Lightweight, therefore fast response to input signals
• It retains both: its strength and flexibility
• Processed ultra-thin, it can achieve high acoustic properties such as a wide dynamic range as well as high resolution
• The material is very stable. It hardly changes over time, does not require long aging (also called "burn in"), and retains its sound quality even in the long run.

Processing this material as an ultra-thin film for audio drivers is extremely complicated and costly.
