Now with SoundRecover, Cassia is a hearing system you can have great confidence in. Cassia employs the same industry benchmark feedback cancellation system, WhistleBlock Technology, as other Spice platform products.

SoundRecover - is the only effective way to extend hearing by restoring high-frequency sounds that would otherwise be inaudible. Audibility of the full spectrum of sounds improves speech understanding, awareness of the sound environment and listening pleasure.

WhistleBlock - Feedback free hearing - WhistleBlock Technology differentiates between naturally occurring feedback-like sounds and true feedback. This means increased audibility and sound quality that is free from annoying feedback.
