Split processing

Signia AX uses two independent processors working in parallel with dedicated tasks.

Focus sounds

Focus sounds carry relevant information where every small detail is important the speech of a conversation partner. These sounds are processed in a highly linear, uncompressed way with emphasis on clarity and details. This pulls speech closer to the listener so it sounds as clear as possible.


Surroundings contain all sounds outside the main focus. These sounds are processed with high spatial resolution, applying more compression and attenuation to keep them at a distance from the focus sounds. Sudden loud sounds are addressed quickly to prevent them from masking focus sounds. This dual process creates both awareness and excitement, for example enjoying piano music and laughter in a cafe.

Small & Stylish

Immersive sound in Signia’s smallest RIC.

The new Pure AX is Signia’s smallest RIC – ideal if you are looking for a sleek aesthetic device that is fully featured.

Signia’s revolutionary Signia AX platform combines an attractive design with outstanding speech clarity even in complex listening environments.
