Sonova also extended Lumity to the Naída power range, Sky pediatric solutions, and a battery-powered model; these devices are stated to work with Roger wireless systems and offer universal Bluetooth connectivity to smartphones, tablets, and laptops.

In cochlear implants, Advanced Bionics’ Marvel CI system can be programmed remotely through Target CI v1.5 and the Remote Support app using smartphone video chat and cloud-based adjustments; Sonova also states that Marvel CI is the only cochlear implant system with a CROS device and supports linked bilateral, bimodal, and CROS configurations.

## Business segments

Sonova officially reports two operating segments: Hearing Instruments and Cochlear Implants. Management states that these two segments are the basis for resource allocation and performance assessment, with EBITA used as a key profitability metric for both segments [41](https://app.finbar.com/go?id=P-754d6424c6244c3696244e78f3361ddd). In FY 2024/25, Hearing Instruments was by far the larger segment at CHF 3,561.4 million, or about 92.1% of group sales, while Cochlear Implants contributed CHF 303.9 million, or about 7.9% [42](https://app.finbar.com/go?id=T-1cd01295238541c4994f0442b039ff90).

Within the Hearing Instruments segment, Sonova further discloses three businesses. The Hearing Instruments business develops, manufactures, and sells hearing aids and wireless communication products through channels including independent audiologists, ENT clinics, large hearing-care chains, and government health agencies [43](https://app.finbar.com/go?id=P-9a95ad138f934005b66f66383fcd916e). This business represented CHF 1,821.4 million of sales, equal to 51% of the Hearing Instruments segment and about 47.1% of total group sales [18](https://app.finbar.com/go?id=T-b84db72c27784d308a33a6ca61aacc2b)[42](https://app.finbar.com/go?id=T-1cd01295238541c4994f0442b039ff90). Audiological Care, operated through AudioNova and other national brands, provides hearing-care services through a network of around 3,600 points of sale in 20 markets and emphasizes personalized care delivered digitally and in-store [44](https://app.finbar.com/go?id=P-dcce3d35811347d0b09723203e701863). It generated CHF 1,487.5 million, or 42% of the Hearing Instruments segment and about 38.5% of group sales [18](https://app.finbar.com/go?id=T-b84db72c27784d308a33a6ca61aacc2b)[42](https://app.finbar.com/go?id=T-1cd01295238541c4994f0442b039ff90). Consumer Hearing, operated under the licensed Sennheiser brand, focuses on premium headphones, audiophile products, early-entry hearing solutions, and soundbars [45](https://app.finbar.com/go?id=P-5a77d47fb53b42809ab03dc69f505eb5). It accounted for CHF 252.5 million, or 7% of the Hearing Instruments segment and about 6.5% of group sales [18](https://app.finbar.com/go?id=T-b84db72c27784d308a33a6ca61aacc2b)[42](https://app.finbar.com/go?id=T-1cd01295238541c4994f0442b039ff90).

The Cochlear Implants segment operates under the Advanced Bionics brand and focuses on implantable hearing solutions for children and adults with severe hearing loss, supported by related sound processing, connectivity, and digital technologies [46](https://app.finbar.com/go?id=P-8f3bfbc02c3749e4bc71dd2870a31efc). Sonova also disaggregates this segment into cochlear implant systems and upgrades/accessories: in FY 2024/25, cochlear implant systems represented 71% of Cochlear Implants segment sales and upgrades/accessories 29% [47](https://app.finbar.com/go?id=T-bd86284877f1417bbb8cd21cb86914c8).

## Company history

Sonova traces its roots to Phonak, which was founded in Switzerland in 1947.[48](https://app.finbar.com/go?id=P-5eecea9ca08b4236a35270d15f81d4a4)[49](https://www.phonakpro.com/il/en/about-phonak/history.html) The company later identified the launch of its first behind-the-ear hearing aid in 1978 as an early milestone in its product history.[50](https://app.finbar.com/go?id=P-7355e82cc3f94ec9aaffa27216c4f4a3) In 2007, Phonak Holding AG was renamed Sonova Holding AG; the change was approved at the June 2007 annual general meeting and took effect on 1 August 2007.[51](https://www.sonova.com/en/investor-news/holding-company-phonak-group-shall-be-named-sonova-holding-ag)[52](https://www.sonova.com/en/phonak-holding-ag-renamed-sonova-holding-ag)

Sonova then expanded through acquisitions. It completed the purchase of cochlear-implant company Advanced Bionics in early 2010, a deal Sonova said gave it a strong presence in both hearing instruments and cochlear implant systems.[53](https://app.finbar.com/go?id=P-2f22e44d8ab84230a40d5940e4baafc2)[54](https://www.sonova.com/en/investor-news/acquisition-advanced-bionics-completed) In 2016, Sonova added AudioNova, one of Europe’s largest hearing-aid retail networks.[55](https://www.sonova.com/en/investor-news/sonova-announces-agreement-acquire-audionova)[56](https://www.sonova.com/en/sonova-completes-acquisition-audionova) A leadership transition followed in 2018, when Arnd Kaldowski succeeded Lukas Braunschweiler as CEO.[57](https://app.finbar.com/go?id=P-d1979d1a00ef40faba9c55218c402236) In 2022, Sonova completed the acquisition of Sennheiser’s Consumer Division, forming a fourth business unit focused on consumer hearing.[58](https://www.sonova.com/en/sonova-completes-acquisition-sennheiser-consumer-division-and-forms-new-business)
[48](https://app.finbar.com/go?id=P-5eecea9ca08b4236a35270d15f81d4a4)[50](https://app.finbar.com/go?id=P-7355e82cc3f94ec9aaffa27216c4f4a3)[53](https://app.finbar.com/go?id=P-2f22e44d8ab84230a40d5940e4baafc2)[57](https://app.finbar.com/go?id=P-d1979d1a00ef40faba9c55218c402236)[49](https://www.phonakpro.com/il/en/about-phonak/history.html)[51](https://www.sonova.com/en/investor-news/holding-company-phonak-group-shall-be-named-sonova-holding-ag)[52](https://www.sonova.com/en/phonak-holding-ag-renamed-sonova-holding-ag)[54](https://www.sonova.com/en/investor-news/acquisition-advanced-bionics-completed)[55](https://www.sonova.com/en/investor-news/sonova-announces-agreement-acquire-audionova)[56](https://www.sonova.com/en/sonova-completes-acquisition-audionova)[58](https://www.sonova.com/en/sonova-completes-acquisition-sennheiser-consumer-division-and-forms-new-business)
