Pure 3Nx


SKU: N/A Category:


Signia Pure Charge is a small 312 battery hearing aid and runs on Signia’s Nx platform. Using Own Voice Processing (OVP) the Signia Motion Nx range can reduce the volume of the user’s making it sound more natural, independent of other voices and sounds in the listening environment.

Signia Pure operates a e 3D Classifier which adjusts the hearing aids automatically to the user’s environment using information on whether the user is moving or static, talking or listening and levels of background noise.

Ultra HD e2e processing allows all the microphone to communicate and stream data to each other allowing the aids to focus on the speech in loud environments, spatial awareness to improve sound localisation and high levels of background noise control.

Signia Pure has an extended dynamic range to a 113dB which allows for a clear sound in loud environments without distortion.

Mfi (made for iPhone) technology and compatible with the Signia myControlApp.
