Overview
Signia Pure Nx BT
The Signia Pure Nx has been discontinued. It has been replaced by the Signia Pure Charge&Go AX. The information below is provided for reference purposes.
The Signia Pure NX was a “made-for-iPhone” hearing aid that used standard batteries and has advanced “Own Voice” technology. Own Voice Processing detected one’s own voice and adjusted automatically to provide clearer, sharper hearing in conversations.
Signia Pure Nx continued a tradition of technological excellence with advanced features like automatic adaptive directionality, SpeechFocus, Tinnitus Management and discrete control from an iOS based smartphone with the myControl app. Signia Pure Nx used high-definition binaural technology to combine the input and processing power of a pair of instruments to allow one to hear more clearly in even the most challenging situations.
Signia Pure Nx included the following technology features:
- Own Voice Processing – Provided “on-the-fly” digital processing of one’s own voice for more lifelike and clearer conversations.
- 3D Classifier – Used a variety of cues from your environment, including movement, to provide better awareness of one’s surroundings and clearer speech understanding.
- Direct Streaming from iPhone – Streamed calls and media directly from iPhone without the need to use an intermediate device like EasyTek.
- myControl App – Discretely controlled one’s hearing aids from iOS based devices.
- TeleCare 3.0 Compatible – TeleCare 3.0 allowed hearing specialists to remotely adjust the programming of the hearing aids without the need for repeated office visits.
