Recently, the Swiss Phonak Hearing Aid has introduced a new Phonak Titanium Series titanium metal hearing aid and a rechargeable Phonak Lidar series hearing aid. The launch of the Phonak Lihang series hearing aids marks that Phonak has applied its groundbreaking built-in lithium battery charging technology to the ear-back machine, which lasts for 24 hours on a single charge and uses titanium 3D printing technology. Titanium is a very strong, durable, widely used, very lightweight metal that is used in high-end medical equipment, high-performance vehicles, and high-quality sporting goods. In the Virto B product of the peak force titanium bucket series titanium hearing aid, Phonak combines the advantages of titanium with the latest 3D printing technology, thus giving birth to the smallest custom machine in the history of Phonak.
