Who Makes Hearing Aids: The Companies Behind the Brands

A surprisingly small number of parent companies manufacture the vast majority of hearing aids sold worldwide. Walk into an audiologist’s office and you might see brand names like Oticon, Phonak, Signia, ReSound, Widex, or Bernafon on the shelf, each with its own marketing identity and product lineup. But trace those brands back to their corporate owners, and the list shrinks to roughly five large groups headquartered mostly in Europe, plus one in the United States. Understanding who actually makes what matters if you are comparing devices, because two brands that look like competitors sometimes share engineering resources, chip platforms, or even parent-company leadership.

The Five Groups That Dominate the Market

The global hearing aid industry has consolidated steadily over the past few decades, leaving a handful of corporations in control of most production. Each owns multiple consumer-facing brands, a structure that lets them target different price points, professional channels, and geographic markets without cannibalizing a single brand’s identity.

Demant, headquartered in Denmark, is one of the largest. It is the parent group behind Oticon, Sonic, and Bernafon hearing aids, as well as Oticon Medical, which makes bone-anchored hearing devices. Demant also holds a licensing agreement with Philips to bring Philips-branded hearing solutions to market, meaning that when you see a Philips hearing aid, the technology and manufacturing come from Demant’s ecosystem, not from Philips’ consumer electronics division.¹

Sonova, based in Switzerland, owns Phonak and Unitron. Phonak is one of the most widely fitted brands globally and has long been known for pushing connectivity features, including early Bluetooth integration. Unitron targets a slightly different segment, often emphasizing flexible trial programs and mid-range pricing. Sonova also acquired the consumer hearing division of Sennheiser, extending its reach beyond traditional hearing aids into the broader personal audio space.

WS Audiology was formed in 2019 through the merger of two established players: Sivantos and Widex. Sivantos itself was the former hearing aid division of Siemens, which had been spun off and rebranded. Under the WS Audiology umbrella, you will find Signia (the successor brand to Siemens hearing aids), Widex, and Rexton, among others. This merger brought together German engineering heritage and Danish acoustic expertise under one corporate roof, though each brand has maintained its own product lines and identity.

GN Group, another Danish company, owns ReSound and Beltone. GN also owns Jabra, the headset and earphone maker, which gives it a dual presence in both medical hearing devices and consumer audio. ReSound was among the first hearing aid brands to offer direct streaming from smartphones, and GN’s cross-pollination between its hearing aid and consumer audio divisions has been a recurring theme in its product development.

Starkey stands apart as the only major manufacturer headquartered in the United States, based in Eden Prairie, Minnesota. Unlike the European groups, which grew partly through acquisition of multiple brands, Starkey markets primarily under its own name. The company has leaned heavily into health-tracking features in recent years, embedding fall detection sensors and activity monitors into its hearing aids.

Why One Company Owns Several Brands

If you are wondering why a single corporation would bother maintaining three or four separate hearing aid brands, the answer comes down to market segmentation and distribution channels. Audiologists and hearing care professionals often develop loyalty to a particular brand’s fitting software, sound philosophy, or training support. Collapsing multiple brands into one would risk alienating those professional relationships. A clinician who has fitted Widex devices for twenty years may have little interest in switching to Signia, even though both now share a parent company. Keeping the brands distinct lets WS Audiology serve both clinicians without forcing a choice.

There is also a geographic dimension. Some brands are stronger in certain regions. Bernafon, for example, has traditionally had a larger presence in parts of Europe than in North America, while Oticon is widely distributed across both continents. By maintaining separate brands, Demant can pursue regional strategies without confusing its global messaging.

The Philips licensing arrangement illustrates yet another reason for multi-brand strategies. Philips is a household name with deep consumer trust, particularly in health technology. By licensing the Philips brand for hearing aids, Demant gains access to that brand equity and to retail channels where Oticon or Bernafon might not have the same recognition.¹ The underlying technology draws on Demant’s R&D, but the product reaches consumers who might never have walked into a traditional audiology clinic.

What the OTC Rule Changed

In 2022, the U.S. Food and Drug Administration finalized a rule creating a new category of over-the-counter hearing aids for adults with perceived mild to moderate hearing loss. Before that, virtually all hearing aids in the U.S. required a visit to an audiologist or hearing instrument specialist, which kept the established manufacturers firmly in control of the market. The OTC pathway opened the door for consumer electronics companies, startups, and direct-to-consumer brands to sell amplification devices without a professional fitting.

The effect was a wave of new entrants. Sony, Bose, and Jabra (already connected to the hearing world through GN Group) launched OTC hearing aids. Apple introduced hearing health features in its AirPods Pro line, including a clinically validated hearing test and hearing aid mode. Smaller companies like Lexie (backed by Bose technology) began selling through big-box retailers and online.

For the traditional Big Five, the OTC category presented both a threat and an opportunity. Some responded by launching their own OTC-oriented products or by making existing prescription-level devices available through broader retail channels. Others leaned into the argument that their prescription devices, professionally fitted and fine-tuned, offer meaningfully better outcomes than self-fit alternatives. The debate over whether OTC devices serve consumers well or leave them with poorly adjusted amplification is far from settled, and it has injected genuine competition into a market that had been remarkably stable for years.

Shared Chips, Different Sounds

A hearing aid is, at its core, a tiny computer with microphones, a processor, a receiver (the speaker that delivers sound into your ear canal), and a battery. The processor chip is where most of the action happens, running algorithms that amplify certain frequencies, suppress noise, and adjust to different listening environments in real time. Each major manufacturer designs or co-develops its own chip platform, and this is where the real differentiation lives. Sonova’s devices run on its proprietary PRISM chip architecture. Starkey uses its own Starkey Neuro Processor. Demant’s brands share a common platform called Polaris.

When two brands share a parent company, they often share the same chip. Oticon and Bernafon, for instance, both draw on Demant’s hardware. What separates them is the firmware, the fitting philosophy, and the sound-processing strategy layered on top. Think of it like two car brands built on the same chassis but tuned differently, one for comfort, the other for sportiness. The physical components overlap, but the driving experience can feel meaningfully different.

This shared-platform approach also means that when a parent company achieves a hardware breakthrough, it can roll it out across all its brands relatively quickly. A new, more power-efficient chip from Demant will eventually show up in Oticon, Philips, Bernafon, and Sonic devices, though each brand’s product release timeline and feature emphasis may differ.

Software and AI as the New Battleground

Hardware improvements in hearing aids have become somewhat incremental, as the devices are already remarkably small and power-efficient. The frontier that manufacturers are competing on now is largely software, specifically the use of deep neural networks and machine learning to process speech in noisy environments. This matters because noise has always been the hardest problem in hearing amplification. A quiet room is relatively easy to handle; a busy restaurant is not.

Recent research has shown how much difference advanced noise-reduction algorithms can make. In one study testing hearing aids equipped with deep neural network-based noise reduction, participants’ ability to recognize sentences in quiet conditions averaged around 87%. When multi-talker background noise was introduced, scores dropped to about 59% using a basic program. But when the hearing aid switched to its most advanced noise-processing mode, scores climbed back up to roughly 82% at the same noise level, an improvement of more than twenty percentage points.² In even noisier conditions, the gap widened further, with the advanced program outperforming the basic setting by more than thirty percentage points.²

Every major manufacturer now markets some form of AI-driven noise management, though they brand it differently. Oticon calls its approach a “deep neural network” trained on millions of sound scenes. Starkey uses the term “Edge AI” to describe on-device machine learning. Phonak emphasizes its “AutoSense OS” system. The specifics vary, but the trajectory is the same: the processor in your ear is doing increasingly sophisticated real-time analysis of the sound environment, decisions that used to require manual program switching by the wearer.

Connectivity and What Comes After Bluetooth

Modern hearing aids from all five major groups support some form of Bluetooth connectivity, allowing users to stream phone calls, music, and other audio directly into their devices. Most current hearing aids use a Bluetooth protocol that streams from smartphones, though compatibility has historically been uneven between Apple and Android devices. Manufacturers have spent years sorting out these interoperability issues, and most recent-generation devices now stream from both platforms.

A newer technology on the horizon is Bluetooth LE Audio with a feature called Auracast. Unlike traditional Bluetooth pairing, which connects one device to another, Auracast works more like a Wi-Fi network: a venue broadcasts an audio stream, and any compatible device within range can tune in. The potential for hearing aid users is significant. Imagine walking into an airport, a theater, or a house of worship and having the public address audio streamed directly into your hearing aids in stereo, with low latency, potentially in multiple languages simultaneously.³

Auracast is designed to replace older assistive listening systems like hearing loops and FM transmitters, which require specialized hardware and are unevenly installed. The catch is that adoption still requires venues to install Auracast transmitters and for hearing aid manufacturers to build compatible receivers into their devices. There are also unresolved technical issues around volume calibration and compensating for the slight delay between the live sound in the room and the streamed audio arriving through the hearing aid.³ Still, most major manufacturers have signaled support for the standard, and it could become one of the most practically meaningful hearing aid features of the next decade.

Why Prices Stay High Despite So Many Brands

A common frustration for consumers is that hearing aids remain expensive, often running into thousands of dollars per pair for prescription-level devices. Part of the reason is that R&D costs are genuinely high. Each new generation of chip, each new noise-reduction algorithm, and each refinement in miniaturization requires significant investment, and the total addressable market for hearing aids is smaller than for consumer electronics like smartphones or earbuds. Those development costs get spread over fewer units.

But market structure also plays a role. With only five major groups controlling most of the supply, and with professional fitting traditionally bundled into the purchase price, there has been limited downward pressure on pricing. The audiologist’s time, the follow-up adjustments, and the device itself have historically been sold as a single package, making it difficult for consumers to comparison-shop the hardware separately. Some clinics have moved toward “unbundled” pricing, where you pay for the device and the professional services separately, which can make costs more transparent. The OTC category has also introduced lower-priced alternatives, though those devices serve a different segment of hearing loss severity and do not come with professional fitting.

Insurance coverage varies widely. In the United States, Medicare does not cover hearing aids, though it covers diagnostic hearing tests. Some Medicare Advantage plans and private insurers offer partial coverage, but out-of-pocket costs for prescription devices remain substantial for many people. This coverage gap has been one of the driving forces behind the push for OTC access.

How the Brands Actually Differ in Practice

Given that brands within the same corporate family share chip platforms and even some software components, you might wonder whether brand choice matters at all. It does, though perhaps not in the ways marketing materials emphasize. The differences tend to show up in a few specific areas.

Fitting philosophy is one. Each brand develops its own “first fit” algorithm, the set of default amplification settings that a newly programmed hearing aid applies based on your audiogram. Some brands lean toward a fuller, more amplified sound from the start, while others ease new users in with a gentler initial prescription that ramps up over time. These default approaches reflect genuine differences in how each brand’s audiological team thinks about adaptation and user satisfaction.

Form factor and industrial design also vary. Some brands prioritize the smallest possible behind-the-ear devices; others emphasize rechargeable battery life or the durability of the casing. Receiver-in-canal styles dominate the market across all manufacturers, but the specific shape, weight, button placement, and charging case design differ enough that comfort and usability can vary noticeably from one brand to another.

Companion apps are another real differentiator. Nearly every manufacturer now offers a smartphone app that lets you adjust volume, switch programs, check battery life, and sometimes fine-tune frequency response. The quality and usability of these apps vary considerably. Some are polished and intuitive; others feel like afterthoughts. Since you will likely interact with the app daily, this is worth testing before committing to a brand.

Costco and Other Retail Private Labels

One wrinkle that confuses the brand landscape further is private-label hearing aids sold through retailers. Costco, the largest single retailer of hearing aids in the United States, sells devices under its own Kirkland Signature brand. These are manufactured by one of the major groups, and the underlying technology closely mirrors a branded product from the same manufacturer, typically from a recent but not current generation. The Kirkland Signature hearing aids have been produced at various times by different partners, including Sonova and GN ReSound, and which manufacturer supplies the current model can change from one product cycle to the next.

The appeal is price. Kirkland Signature hearing aids cost substantially less than their brand-name equivalents, partly because Costco’s business model depends on high volume and lower margins, and partly because the bundled professional services at Costco’s hearing centers operate differently from independent audiology clinics. The trade-off is that you get the hardware at a discount but may have fewer follow-up appointments, less customization, and a more limited selection of accessories compared to working with an independent audiologist who carries multiple brands.

Other retailers and online sellers offer similar private-label or white-label arrangements, where the physical device comes from one of the Big Five’s factories but is sold under a different name. If you ever find a hearing aid brand you have never heard of and wonder who is behind it, the answer is almost always one of the five major groups supplying the hardware under a manufacturing or licensing deal.

Where the Industry Is Headed

The boundaries between hearing aids and consumer earbuds are blurring. Apple’s entry into hearing health features, Sony’s OTC devices, and Jabra’s straddling of both the hearing aid and consumer audio worlds all point in the same direction. For the traditional manufacturers, this convergence is both a risk and a validation. They have decades of audiological expertise and clinical relationships that consumer electronics companies lack, but they are facing competitors who know how to scale hardware production and build consumer software experiences at a level the hearing aid industry has not historically matched.

Regulatory frameworks are also still catching up. The OTC rule addressed a significant access gap, but questions remain about how to ensure that self-fit consumers receive adequate amplification without professional guidance, and how to handle the grey zone of moderate hearing loss where both OTC and prescription devices could theoretically serve the patient. Meanwhile, hearing aid manufacturers are integrating health-monitoring features like heart rate tracking and fall detection, pushing these devices toward the broader wearable health market and potentially opening new regulatory and reimbursement conversations.

For now, if you are shopping for hearing aids, the practical takeaway is straightforward: start by understanding the corporate family tree. Knowing that Oticon and Bernafon share a parent, or that Signia and Widex sit under the same roof, helps you evaluate whether you are genuinely comparing different technologies or choosing between two flavors of the same underlying platform. An audiologist who carries brands from at least two different parent companies can offer you a more meaningful comparison than one who carries three brands that all trace back to the same manufacturer.
