Sonova to Supply Costco Kirkland Signature (KS9) Hearing Aids

Sonova, the Swiss-based parent group of Phonak, Unitron, and Hansaton, confirmed that it has been awarded the contract to supply Costco’s Kirkland Signature 9.0 (KS9) hearing aids. Although the KS9 will use Sonova's wireless SWORD chip set, the new product is said to be unique in many important ways from the other hearing aids in the Sonova group.
