C-ISP is strong and now open for continuous alignment of all algorithms based on inputs from both ears.

The platform for natural sound C-ISP communication platform clear440 is a unique hearing aid – powerful on its own but strongest when coupled. The C-ISP communication platform in clear440, with a total of three individually designed chips, makes this new power possible. The natural next-step in the evolution of hearing aid platforms, it is devised to open the signal processing to input from a coupled hearing aid and take integrated signal processing to a new level. • C-ISP ensures interaural coupling of the hearing aids. A clear440 hearing aid will perform strongly on its own, and even...

The technology for natural sound WidexLink™ – the timing is right Natural sound was the inspiration for clear440. Our next challenge was to develop a robust wireless link to facilitate seamless communication and coordination between hearing aids – the best possible premise for natural sound. WidexLink is the exclusive resu

Real sound in real time The first, full-feature wireless link – designed especially for hearing aids Proprietary WidexLink™ is a wireless, high-speed data transmission technology that allows instant, ongoing communication between hearing aids and direct connection to external audio devices. Because of its speed and robustness, WidexLink allows instant synchronisation and coordination between hearing aids. This not only enables technologies to work effectively in one hearing aid – more importantly it ensures that a coupled pair of clear440 hearing aids have great potential in regard to sound...

Up until now it has been difficult to truly reap the benefits of near-natural sound in two hearing aids linked together. Our solution is the unique InterEar or IE. This ensures both coordination and synchronisation seamlessly. InterEar also ensures that the hearing aids communicate with each other up to 21 times a second, resulting in instantaneous near-natural sound in both.

The experience of natural sound Stay in sync The Widex clear™440 models add new dimensions to signal processing, taking users closer to a natural sound experience that is audible, comfortable and understandable. The development of clear440 signal processing was inspired by fundamental characteristics of normal hearing; for instance, the ability to single out a distinct speaker and to use the Interaural Level Difference. Our aim has been to exploit the potential of Widex­ Link to add a new dimension in processing. We call this 3D TruSound. 3D TruSound is natural sound perception and sound...
