Sona hit the market in 2010 as a division of the Sonova Group- the parent company of Phonak. Sona is the first major hearing aid company to offer upgradable hearing aids.
Sona hearing aids may be programmed with entry-level, mid-level, or advanced features – right in the office. The physical hearing device is the same at all price points, and the programming alone is what dictates the cost. This allows someone to start out investing in an entry-level hearing aid, while maintaining the ability to pay for an upgrade at a later date.
