The Oticon Siya Full Shell hearing aid is an easy-to-handle instrument that fills out most of the visible part of the ear rather than just the ear canal. Because it is larger than other types of in-the-ear hearing aids, it can accommodate longer-lasting batteries and larger manual control options. Oticon Siya Full Shell features optional Bluetooth wireless technology for seamless connectivity to your favorite devices. It also offers an optional telecoil for enhanced listening in public settings with loop systems, such as the theater or cinema.
