From chip design to retail: where value is captured and margin sits at every link
SEER SONUS Research·
Figure · Where Margin Sits
A US$15–30 chip is marked up layer by layer until it reaches the consumer at US$3,000–8,000. Manufacturing 65–75%, distribution/retail 75–80%, and aftercare 70–85% hold the fattest margins — and distribution is the epicenter of value migration.
The Value Chain in Full
A hearing aid starts as a chip worth a few dozen dollars, accumulates value through multiple layers, and reaches the consumer's ear at a retail price of US$3,000–US$8,000. Understanding how each layer captures value is the foundation for predicting where the industry is headed.
The full hearing aid value chain breaks down into six layers, each with sharply different competitive dynamics, barriers to entry, and profit structures:
The six-layer hearing aid value chain, from semiconductors to aftercare
The most striking phenomenon across these six layers is the migration of value. Traditionally, the brand manufacturers (the Big 5) captured the lion's share of profit by controlling distribution. But with the opening of OTC regulation, the entry of large retailers like Costco, and the arrival of AI operating tools, value is shifting from "product markup" toward "service + data." This structural shift is redefining who holds the greatest bargaining power in the chain.
We analyze each layer in turn below.
The Chip Layer: A Hidden Battlefield
The hearing aid chip is one of the most extreme low-power computing platforms in the world. Within a power budget of just ~1mW, it must simultaneously handle multi-channel DSP (16–64 band compression), deep neural network inference (scene classification, speech enhancement), Bluetooth LE Audio connectivity, and multi-sensor data fusion. These demands make the hearing aid ASIC one of the most difficult niche markets in all of semiconductor design.
01
Intrinsicon (WS Audiology supplier)
Supplies custom ASICs to WS Audiology (Widex + Signia), the world's largest hearing aid group. The designs are highly optimized for hearing aid use cases, with deeply integrated DNN accelerators.
02
ON Semiconductor Ezairo platform
An open platform architecture that lets small and mid-size brands build products on standardized chips. The Ezairo 7160 SL combines an ARM Cortex-M33, dual DSP cores, and BLE 5.3, making it the most widely adopted commercial platform today.
03
Sonova SWORD chip (in-house)
Sonova is the only hearing aid manufacturer that designs its chips entirely in-house. The SWORD (Sonova Wireless One Radio Digital) chip is built for the Phonak product line and delivers industry-leading low-latency Bluetooth streaming (<15ms).
04
Starkey Edge AI processor (in-house)
Starkey's Edge Mode chip integrates a real-time AI environment-analysis engine, performing on-device scene recognition without a cloud connection. It also embeds a 3D accelerometer and PPG sensor to support health monitoring.

Chip-to-retail value leverage
Two distinct strategic paths have emerged: in-house silicon (Sonova, Starkey) versus outsourced silicon (WS Audiology and GN Hearing on ON Semi / Intrinsicon). The in-house route offers deeper hardware-software integration and differentiation, but demands sustained R&D investment of US$50–100M+ per year.
R&D and IP: Where the Moat Lives
The core moat in hearing aids lies in algorithm IP rather than hardware specs. The Big 5 collectively invest roughly US$1.2–1.5B in R&D each year — a share of revenue far above most of consumer electronics.

Patents create a formidable barrier to entry. Core noise-reduction algorithms, DNN architectures, and feedback-cancellation methods are all tightly protected. Even a new entrant with chips and manufacturing capability struggles to design around these patents — one of the structural reasons the Big 5 hold 90%+ market share.
Manufacturing and Cost Structure
The gap between a hearing aid's low bill of materials (BOM) and its high retail price creates a profit structure rarely seen in consumer electronics. A mid-tier RIC hearing aid carries a core material cost of about US$50–80, yet retails for US$2,000–4,000 per ear.
BOM breakdown of a typical mid-tier RIC hearing aid:
DSP chip 25%
Receiver 14%
Microphones ×2 10%
Battery / charging module 18%
Housing / structural parts 8%
Connectors / PCB 12%
Other (wires, wax guards) 13%

Notably, a low BOM and high gross margin do not translate into an equally high net margin. Brand manufacturers reinvest heavily in R&D (8–11%), distribution buildout (20–30%), and marketing. Net margins typically land at 15–22% — still very healthy.
Distribution: The Epicenter of Value Migration
Distribution and retail is the layer undergoing the most dramatic structural change in the hearing aid value chain — and the one that most directly shapes the strategy of hearing-care retailers.
Channel market share:
Independent clinics 40%
Retail chains (Amplifon, etc.) 25%
Big-box retail (Costco) 15%
VA / government procurement 15%
Online / DTC 5%
Global hearing aid sales by channel
Amplifon deep dive:The world's largest hearing-care retail chain posted over €2.2B in revenue in 2024, operating 9,500+ locations across 26 countries with 19,000+ employees. Its single-store economics: ~€230K average annual revenue per store, 1.5 audiologists, and an average order value of €1,200–1,800 (with insurance subsidies in Europe). Amplifon's core strategy is scaling through the acquisition of independent clinics — more than 500 independent clinics acquired over the past five years.
The Costco disruption:Through its Kirkland Signature brand (made by Sonova, equivalent to Phonak technology), the Costco Hearing Aid Center offers flagship-grade hearing aids at US$1,499/pair — the same technology sells for US$4,000–6,000+ at independent clinics. This aggressive price gap is accelerating channel disintermediation.

The table reveals a key insight: the AI-enabled operations model delivers the highest customer lifetime value. AI operating tools cut labor costs while lifting retention and service revenue through personalized remote care, proactive follow-up reminders, and data-driven upgrade recommendations. This is exactly how value migrates from "product markup" toward "service + data."
Aftercare: An Underrated Profit Pool
Aftercare is the most underrated profit pool in the hearing aid value chain. A user's journey extends far beyond the purchase: hearing aids last 4–6 years on average, and demand ongoing professional care throughout.

Sonova service-revenue growth vs. product
Teleaudiology as a profit amplifier:Remote adjustments cut audiologist time per visit from 30–45 minutes to 10–15, while eliminating patients' travel cost and time barriers. Sonova reports that its remote-care service runs 15–20 points higher in margin than in-person visits.
In the AI-enabled operations model, the platform proactively analyzes usage data (daily wear time, environment-switching frequency, volume-adjustment patterns) and triggers care reminders before problems arise — turning passive waiting for follow-ups into active, continuous care. This lifts satisfaction and retention while transforming aftercare from a cost center into a scalable profit center.
Structural Inflection Points
Taken together, the global hearing aid industry stands at three mutually reinforcing structural inflection points:
01
Value migrates from products to services and data
The old model of selling hardware on markup is giving way to a composite of hardware, continuous service, and data insight. Sonova's service revenue now grows at twice the rate of products, and Amplifon's strategy has shifted from selling more hearing aids to cultivating customer lifetime value. For retailers, competitiveness is now defined by service capability and data assets rather than procurement cost.
Amplifon acquires 80–100 independent clinics a year. Costco eats into the entry market on sheer price. OTC deregulation removes the need for a professional channel in the mild-loss segment. Independent clinics face a structural squeeze from both ends: pressured by chains at the high end, displaced by big-box retail and OTC at the low end. Survival depends on building differentiated service that chains cannot replicate.
03
AI operating platforms become the new retail moat
As products converge (the technology gap among the Big 5 keeps narrowing) and pricing grows transparent (Costco's price sets a public benchmark), retail competitiveness will hinge on operational efficiency and customer experience — exactly where AI operating platforms add value. AI lowers labor cost and sharpens fitting precision, and, more importantly, builds data-driven continuous care: a structural advantage traditional models cannot scale.
The convergence of these three inflection points is opening a historic strategic window for the industry's middle layer — the independent hearing-care retailer that is neither a global giant nor a national chain. Using AI as leverage, they can outperform larger rivals on service quality and operational efficiency, building a durable moat around data and customer relationships.
