Sonova unveils revolutionary new wireless chip

SWORD™ (Sonova Wireless One Radio Digital) chip

Sonova introduces a Made For All 2.4 GHz wireless chip. The SWORD™ (Sonova Wireless One Radio Digital) chip enables direct connectivity to any cell phone* as well as ear-to-ear communication using only one single radio technology. As it supports the classic Bluetooth®**protocol, it provides direct connectivity to cell phones – including Android™, iPhone® and even classic cell phones – with no extra body-worn streaming device required.

It also works seamlessly with Sonova proprietary 2.4 GHz wireless protocols, including AirStream™ technology, enabling a new plug and play solution for high-quality TV streaming with excellent stereo sound quality1. This breakthrough chip will make its debut in the Phonak Audéo™ B-Direct hearing aid, which will allow true hands-free calling. The chip technology will power future generations of hearing aids with even more sophisticated connectivity features across all Sonova’s product brands Phonak, Unitron, Hansaton and Advanced Bionics. 


Our revolutionary SWORD chip is a prime example of how technological leaps are possible when companies truly listen to their customers. Customer feedback revealed there is both a strong desire and a tremendous opportunity for a solution that provides direct connectivity for all hearing aid wearers. By offering a solution to the entire market – including the more than 80% of the world’s smartphone owners who purchased Android devices – Sonova becomes the first and only major hearing aid company to unlock the enormous potential of universal direct connectivity. Our chip will be the foundation for a wide variety of unique and innovative solutions in the coming years. The Phonak Audéo B-Direct hearing aid is only the beginning.

Phonak Audéo B-Direct: instantly connects, easy-to-use, plug and play


The Phonak Audéo B-Direct Receiver-In-Canal hearing aid extends the successful Audéo B family and is the first product to reap the benefits of the new SWORD chip, offering direct connectivity to any Bluetooth phone*, no matter if one uses iOS, Android or any other cell phone. This Phonak hearing aid is based on the innovative Belong™ platform. It simplifies the life of hearing aid wearers by offering them the freedom of direct connectivity, hands-free calling, and excellent TV sound quality. Hearing aid wearers can answer or reject a phone call without touching the phone by pushing the button on their hearing aids. When answered, the wearer’s voice is picked up by the hearing aid’s intelligent microphone network and transmitted to the other caller providing truly hands-free calling. The TV Connector, the new plug and play solution, easily connects and delivers TV audio streaming to multiple Audéo B-Direct wearers simultaneously. This essentially turns a person’s hearing aids into wireless TV headphones.

Phonak Virto™ B, the world’s first hearing aids with Biometric Calibration

At the same time Phonak introduces Phonak Virto™ B, the world’s first hearing aids with Biometric Calibration. Each ear is unique and each ear hears differently. Identifying over 1,600 data points, the Phonak proprietary 3D modelling software calculates the unique calibration settings for each Virto B hearing aid. The result is a 2 dB improvement in directionality leading to better hearing performance1. Virto B comes in a full product family launch.
