The Bernafon Zerena 9 RIC is a premium receiver-in-canal hearing aid that was available exclusively through Costco Hearing Aid Centers. Built on Bernafon's DECS (Dynamic Environment Control System) technology, the Zerena 9 represents the top-tier performance level in the Zerena family, offering advanced sound processing and noise management for a wide range of listening environments.

The Zerena 9 miniRITE uses a size 312 battery and features Bluetooth 2.4 GHz connectivity for hands-free phone calls streamed directly to both ears. It is compatible with Android, iPhone, and other Bluetooth-enabled audio devices. The companion Easy Control-A app allows users to adjust volume, switch programs, mute the hearing aids, check battery status, and locate a misplaced instrument with the "Find my hearing instrument" feature.

Key features include wireless audio streaming, multiple listening programs, push-button controls, and four available power levels to accommodate a range of hearing loss from mild to severe. The BBS (Behind-the-ear Battery System) design ensures a comfortable and discreet fit.
