In recent developments, Sonova completed the acquisition of Sennheiser Consumer Division in early 2025, enhancing its over-the-counter hearing aid offerings and integrating the hearX technology platform for direct-to-consumer sales. The company announced a strategic partnership with Amazon in mid-2025 to expand distribution of OTC hearing aids via online marketplaces, alongside launching the Phonak Lumity platform update with AI-driven sound processing improvements. Additionally, Sonova secured a CHF 500 million funding facility in Q3 2025 to support expansion into emerging markets in Asia and Latin America.
