Who owns Sennheiser?

The legendary German brand Sennheiser has considerable weight in the world of audio, both in the consumer and professional space. Of course, it’s one of the leading headphone brands, and Sennheiser wireless headphones are extremely reliable. Still, if you go to enough concerts, there’s a good chance you’ll also see your favorite singer rocking Sennheiser wireless mics.

Is the company still German? Well, the duality of Sennheiser’s offerings (high-end professional gear and capable consumer headphones) also applies to ownership. Sonova Holding, a Swiss hearing aid company that acquired the Sennheiser Consumer division in 2022, is in charge of consumer products like wireless headphones. Meanwhile, the Sennheiser family still owns the brand and manufactures professional audio products. Pro line equipment is manufactured in factories in Germany and Ireland, and products for casual consumers come mainly from Romania.

This does not, however, demean the brand. Sonova has a perpetual licensing agreement to use the legendary name, but the Sennheiser company itself is a family business. It’s not uncommon in the audio world for large companies to expand their presence in the industry by purchasing a trusted brand (Cosonic, a Chinese company, bought Beyerdynamic, for example), but Sennheiser remains true to its roots. Specifically, the third generation of the Sennheiser family owns the majority of the company.

Sennheiser began life as a small microphone manufacturer in the mid-1940s. Only a decade later, the company began a series of major innovations at a time when audio equipment was in its infancy. In 1956, it manufactured the first-ever shotgun microphone, a high-direction microphone that picks up sound from only one direction and ignores ambient noise. Only a year later, Sennheiser developed a professional wireless microphone system for television.

Sennheiser consolidated its position in headphone history a few years later. The HD 414 from 1968 was the world’s first open-back headphone, and many believe it still sounds great. Naturally, the company continued to innovate and eventually produced one of the most legendary professional headsets of all time, the HD 25 – so legendary in fact that it remains in production despite its introduction in 1988.

When Sonova Holding purchased the license for part of Sennheiser, its consumer-focused headphones lived up to the brand name. For example, the Momentum series headphones, which are premium Bluetooth models powered by ANC, have been well received by the general public, and some have even said that they sound better than the Apple AirPods Max. Although Sonova has decided to sell the Consumer division in 2026, given Sennheiser’s history, whoever takes over will also benefit from a reliable platform to launch consumer headphones – hopefully a company that lives up to the brand’s legendary pedigree.
