Sennheiser statistics span two related but distinct reporting contexts: the Sennheiser Group’s professional-audio business and Sennheiser Consumer Hearing under Sonova. The figures below make the population, geography, currency, and measurement period explicit so revenue, workforce, research, and product data are not mistaken for one another.

Revenue Scale and Recent Sennheiser Trends
The Sennheiser Group reported €492.3 million of turnover in fiscal 2024, a company-reported measure for the Group. The same annual-report source says turnover fell 6.6%, or €34.9 million, versus fiscal 2023, after three consecutive years of growth; these are reported changes, not independently reconstructed calculations. Sennheiser Group Annual Report 2024
| Reporting context | Period | Sales or turnover | Definition |
|---|---|---|---|
| Sennheiser Group | Fiscal 2024 | €492.3 million | Group turnover |
| Sennheiser Group | Fiscal 2024 vs 2023 | -6.6% | Reported year-over-year turnover change |
| Sennheiser Group | Fiscal 2024 vs 2023 | -€34.9 million | Reported turnover decline |
| Sennheiser Group | Fiscal 2023 | €55.4 million EBIT | Operating result, not net income or cash flow |
| Sonova Consumer Hearing | 2024/25 | CHF 252.5 million | Consumer Hearing sales |
| Sonova Consumer Hearing | 2023/24 | CHF 239.7 million | Consumer Hearing sales |
The Sonova figures are a separate parent-company reporting context. Consumer Hearing sales were CHF 252.5 million in 2024/25, compared with CHF 239.7 million in 2023/24, while Sonova total sales were CHF 3,865.4 million and CHF 3,626.9 million in those respective periods.
Parent-group figures should not be presented as Sennheiser-only revenue. Notes to the Consolidated Financial Statements – Sonova Annual Report 2024/25
Sennheiser Revenue by Region and Market
Sennheiser’s 2024 regional revenue figures show the Group’s reported geography in euros, while the Sonova figures below use Swiss francs and cover Sonova reporting areas. They are useful for scale and market context, but they are not interchangeable datasets.
| Sennheiser Group geography | 2024 revenue | Period and currency |
|---|---|---|
| EMEA | €232.1 million | 2024, euros |
| Germany | €78.8 million | 2024, euros |
| APAC | €109.7 million | 2024, euros |
| Americas | €150.5 million | 2024, euros |
The Sennheiser Group Annual Report also recorded €76.1 million of German revenue in fiscal 2023, up 19.7% year over year; the source labels this as professional-audio revenue, not consumer-headphone revenue. Sennheiser Group Annual Report 2024
Sonova’s 2024/25 market figures provide a different frame of reference: EMEA excluding Switzerland generated CHF 1,943.4 million, the United States CHF 1,156.8 million, the Americas excluding the United States CHF 278.9 million, and Switzerland CHF 29.8 million. In 2023/24, Sonova EMEA excluding Switzerland was CHF 1,828.4 million and United States sales were CHF 1,074.0 million. Notes to the Consolidated Financial Statements – Sonova Annual Report 2024/25
Sennheiser Employee and Workforce Statistics
Sennheiser reported 2,196 employees worldwide on December 31, 2024. The geographic breakdown was 1,825 in EMEA, 1,398 in Germany, 229 in APAC, and 142 in the Americas; these are point-in-time company headcounts, not annual averages. Sennheiser Group Annual Report 2024
| Workforce measure | Count or share | Period and population |
|---|---|---|
| Worldwide employees | 2,196 | December 31, 2024; Sennheiser Group |
| EMEA employees | 1,825 | December 31, 2024 |
| Germany employees | 1,398 | December 31, 2024 |
| APAC employees | 229 | December 31, 2024 |
| Americas employees | 142 | December 31, 2024 |
| Production employees | 406 | 2024; worldwide |
| Apprentices | 26 | December 31, 2024; worldwide |
Production employment was 406 people worldwide in 2024, including 291 at Wennebostel, Germany, and 115 at Braşov, Romania. The reported workforce composition was 38% women and 62% men, while women held 22% of management positions on December 31, 2024.
The later company-reported snapshot lists 1,390 employees in Germany in 2025 as of December 31 and 24 apprentices worldwide. Because the dates and definitions differ, the 2025 Germany count should not be treated as an annual average or as a direct replacement for the 2024 worldwide breakdown.

Sennheiser Research, Patents, and Operating Footprint
Sennheiser’s 2024 innovation measures included about €49 million invested in research and development, 22 new patents registered, 235 patent families, and 182 granted patents. Patent families, newly registered patents, and granted patents are different measures and should not be added together. Sennheiser Group Annual Report 2024
| Innovation or footprint measure | Reported figure | Period and geography |
|---|---|---|
| R&D investment | About €49 million | 2024; worldwide |
| New patents registered | 22 | 2024; worldwide |
| Patent families | 235 | 2024; worldwide |
| Granted patents | 182 | 2024; worldwide |
| Sales subsidiaries | 25 | December 31, 2024; worldwide |
| Sales partners | 55 | December 31, 2024; worldwide |
The company-reported distribution footprint later listed 31 sales subsidiaries and 17 distributors as of December 31, 2025. A distributor count is not a count of countries or retail outlets, so it describes channel structure rather than market coverage. Sennheiser Group Annual Report 2024
Sennheiser Consumer Hearing Statistics Under Sonova
Sennheiser Consumer Hearing has a distinct ownership and reporting history. Sonova acquired 100% of the Consumer Division on March 1, 2022, and the former consumer division operated with around 600 employees worldwide in 2022/23. Advancing our people – Sonova Annual Report 2022/23
Sonova’s 2024/25 Consumer Hearing business report describes China expansion across four named city tiers: Tier 1, Tier 2, Tier 3, and Tier 4. This is a scope description of the expansion strategy, not a percentage of market share. Consumer Hearing business – Sonova Annual Report 2024/25
Sonova’s 2024/25 financial disclosures also separate recognized revenue by timing. Hearing Instruments segment sales were CHF 3,561.4 million and Cochlear Implants segment sales were CHF 303.9 million; point-in-time recognized sales were CHF 3,698.8 million and over-time recognized sales were CHF 166.6 million.
These are Sonova figures, not Sennheiser-only revenue, and the recognition categories should not be treated as consumer-headphone sales. Notes to the Consolidated Financial Statements – Sonova Annual Report 2024/25
Sennheiser MOMENTUM 4 Sales and Product-Use Statistics
The MOMENTUM 4 launched worldwide in August 2022 and had sold more than 1 million units by the 2024/25 report. The cumulative sales threshold is company-reported and not independently audited, so it should be read as a “more than” milestone rather than an exact unit total. Sonova Annual Report 2024/25 Business Report
| MOMENTUM 4 measure | Reported figure | Definition |
|---|---|---|
| Launch | August 2022 | Worldwide product launch month |
| Cumulative sales | More than 1 million units | By the 2024/25 report; worldwide |
| Rated battery life | 60 hours | Manufacturer specification |
| Sales-volume trend | Increased | 2024/25; worldwide |
The product is rated for 60 hours of battery life, which is a manufacturer specification rather than an observed average of customer use. The 2024/25 report also says MOMENTUM 4 sales volumes increased during that period; no percentage increase is supplied. Sonova Annual Report 2024/25 Business Report
The broader interpretation is therefore bounded: the dataset supports a cumulative sales milestone, a launch month, a battery-life rating, and a direction-of-trend statement, but it does not provide a market-share percentage or independently measured usage outcome.
