The current generation is manufactured by Signia (formerly known as Siemens).
Kirkland branded hearing aids are actually made by one of the major manufacturers who go through a bidding process against each other for the rights to build the Kirkland Signature package. Typically Costco will go with the company willing to give them the best pricing on the package. The package is just a specially priced bundled of product and service. Currently they are made by Signia which is the new name for the old Siemens company. Signia also builds the Rexton brand sold by Costco. In previous years the Kirkland aids were built by GN Resound.
The KS 8 model is actually manufactured by Rexton which is a sister company to Signia (Siemens). If you goto Costco.com they have a lot of information on it under the hearing center tab.
