The best of the ERKA tradition, reduced to the essentials.
The geometry of the acoustic chamber - perfected over decades - in combination with the modern ERKA dual membrane provides optimal auscultation over the entire frequency range. The auscultation is optimized by the high specific gravity of the brass body, as this reliably prevents noise interference.

The construction of the patented ERKA dual-membrane allows for an additional resonance chamber which optimises the sound.
The non-chill ring ensures patient comfort and protects the membrane.
Highly polished and chromium-plated for a non-porous surface, the brass chest-piece ensures perfect surface hygiene.
Through the separately integrated spring in the tube, there is no acoustic loss from the chest-piece to the ear.
The ergonomically designed, super soft ear tips create an excellent acoustic seal against external noise interference and maximize wearer comfort and fit.
The standard 15° inclined binurals can be individually adapted to the ear canal characteristics of the user.
