Sennheiser has spent over 80 years building a reputation in professional and consumer audio. Now, through its consumer hearing division operating under the Sennheiser brand, that same acoustic expertise is being applied to a very different product: over-the-counter hearing aids. The result is the All Day Clear lineup, FDA-cleared devices aimed at adults with mild to moderate hearing loss who want a capable, self-fitting solution without a clinic visit.
The timing matters. OTC hearing aids became a formal product category in the US in 2022, and the market has grown quickly since. Sennheiser’s consumer hearing business, which operates under Sonova’s licensing of the Sennheiser trademark, was early to this space and has stayed competitive on both price and features.
Two Models, One Goal:
The current lineup includes two devices: the All Day Clear and the All Day Clear Slim. Both carry FDA clearance and use a receiver-in-canal design, meaning the main body sits behind the ear while a small speaker delivers sound directly into the ear canal.
Both models offer up to 16 hours of battery life on a single charge, Bluetooth connectivity for iPhone and Android, hands-free calling, and intelligent scene detection that adjusts sound based on your environment. Directional microphones help target specific sounds more efficiently. The All Day Clear is priced at $949.95 per pair, making it one of the more accessible options in the premium OTC segment.
App-Driven Personalization:
The All Day Clear app guides users through an initial setup and allows for ongoing personalization without needing an audiologist appointment. You create a sound profile, make adjustments manually, or let the automatic sound mode handle optimization as your environment changes.
The app supports streaming of music, podcasts, and audiobooks, and in-the-moment volume and balance controls are available directly from the hearing aid’s push button as well. Both models are also eligible for purchase with FSA and HSA accounts. This makes them more accessible to buyers who already have funds set aside for healthcare expenses.
Performance in Real Conditions:
Lab testing by HearAdvisor found the All Day Clear Slim delivered above-average speech clarity in quiet environments and strong music streaming quality, both areas where Sennheiser’s audio background appears to benefit the product.
In independent audiology testing, Sennheiser performs impressively with background noise, in some cases matching the performance of prescription-grade devices. That is a meaningful benchmark for OTC buyers who spend time in noisy environments like restaurants, meetings, or public transit.
Where it Fits in the Market:
Forbes Health named the All Day Clear the best OTC technology hearing aid of 2024, based on audiologist recommendations. It has maintained strong rankings in 2025 comparisons across multiple independent review platforms.
The device is available directly through the Sennheiser hearing website, as well as through Best Buy and Amazon. Buyers who want professional guidance without committing to a clinic can also access optional audiologist support through some authorized retailers. This flexible distribution model suits buyers who are comfortable self-fitting but still want a safety net.
What Buyers Should Know:
The All Day Clear is built specifically for perceived mild to moderate hearing loss. It is a self-fitting device, which means the onboarding process works best when users follow the app setup carefully. The devices come with multiple ear tip sizes and wax guards in the box, and most retailers include a return window between 45 and 60 days.
One useful anchor for buyers evaluating Sennheiser alongside other brands: look at how it handles background noise separation and Bluetooth latency during calls, as these are the areas where budget OTC devices tend to fall short. Sennheiser’s background in audio engineering gives it a credible foundation here, and independent test data backs that up.
Proven Audio Background:
Sennheiser’s move into the OTC hearing aid space is a logical extension of what the brand already does well. The All Day Clear lineup brings together Sonova’s medical-grade hearing technology and Sennheiser’s acoustic heritage in a package that is accessible, app-driven, and well-reviewed across independent audiology platforms.
