We developed Euridiche Minima collecting all experiences from the two bigger models, to create the finest electrostatic sound with intimate music experience, also using the possibilities of the innovative 3D printing technology. With this model, the purpose was to build smaller and lighter headphones, without compromising the flow of emotions through music. Euridiche Minima uses all innovative features like Euridiche 3D, but with a smaller, one-way driver system. As a result, Euridiche Minima is a lightweight, easily wearable, and transportable headphone. Enjoyable for demanding music listening and for working too.

Design Innovations

  • Sectioned two-way stator design with several advantages (Euridiche and Euridiche 3D):
    – With a built-in switch, the tonality of the headphones can be regulated in 3 steps, depending on your preference, record, and used system, in the high-frequency band. (1KHz and above)
    – This configuration gives you a real 3D sound field because the high-frequency content is focused from the front side of the membrane to your ears, and not from the center as it usually is, on the headphones.
  • Air Flow stator matrix design gives you possible minimal air turbulence during air motion through them. The segments are aerodynamically designed, like the wings of airplanes. This way we can eliminate all of the harshness caused by any other perforated type of stators.
  • The segments of the stator matrix are focused backward directly on your ears, to create a sound stage like a live orchestra in the concert hall, or the loudspeakers in your listening room.
  • Easily changeable membrane capsule, for lifetime durability of our product. The only thing in the electrostatic driver that can be damaged over years, is the extremely thin membrane. The owner can change them easily without soldering, just with a few screws. That is the reason why the screws aren’t hidden.
  • Standard XLR/mini XLR connectors for easy cable change and easier storage.


Our standpoint in designing the manufacturing processes is, to keep the principles and materials which have been proven over time, combined with the newest scientific approach.

From hand-sewn genuine Italian leather parts, through laser cutting, to the newest 3D printing technology, all parts are carefully hand assembled.

Why 3D printing?

  • The newest 3D printing technology gives a precise, repeatable, durable product, ideal for high-quality low mass production.
  • Also ideal for Research and Development, both for new, and for existing products.
  • Possible manufacturing, extremely lightweight and strong peaces, hollowed out inside. This is important for your comfort during long listening sessions.
  • Parts with this complexity can’t be manufactured by other technologies.
  • We use high-performance biopolymer made from renewable resources. The material is fully biodegradable and compostable.
The built in 3 pin mini XLR connector allows an easy wire disconnecting from your Euridiche headphones, for cable changing or easier storaging.
Hand crafted genuine leather ear pads and head band are built in for good humidity handling during listening sessions to prevent any unpleasant or allergic reaction.

Electrostatic Headphone Driver Unit

With the Soltanus Acoustics Electrostatic Headphone Driver unit we ensure the required High-Voltage audio signal necessary for the electrostatic headphones.
The design is the most simple and robust as possible, with high-quality built-in materials to match the outstanding electrostatic sound quality.
This device with its uncolored sound leaves you the freedom in choosing the amplifier or headphone amplifier just to your taste.
There are no additional unnecessary electronics integrated, only the two audio transformers and a simple power supply to make the signal path absolutely simple.
Our Audio step-up transformers are wounded by hand to ensure the highest quality in the high-frequency range and use extremely oversized cross-section cores, which enables high impedance and outstanding low-frequency reproduction.
The housing is made from solid 6mm and 3mm aluminum alloy sheets, preventing vibrations or generating any eddy currents by transformers.
The housing can be used vertically, to use it as a headphone stand, and horizontally too, as usual.
