Sennheiser All-Day Clear review

The All-Day Clear is a rechargeable, Bluetooth-enabled, self-fitting OTC hearing aid, cleared for adults 18 and over with perceived mild to moderate hearing loss. Sennheiser publishes an app for the fitting process, which is the mechanism by which a self-fitting device is set up: the wearer completes a guided procedure through the phone app rather than an audiologist adjusting the device remotely or in person.

The name recognition matters less than the regulatory category here. Whether a device is made by a household audio brand or a dedicated hearing aid manufacturer, an OTC hearing aid has to meet the same FDA rule: cleared for perceived mild to moderate loss in adults, sold without a prescription, with output limits the FDA sets for the category. See what is an OTC hearing aid for what that clearance does and does not certify.

At just under $1,000, the All-Day Clear competes directly against devices that cost roughly the same or more but include a different level of support. The Jabra Enhance Select 300 sits close in price and bundles remote audiology support. The Jabra Enhance Select 700 is about double the price with the same supported model on a newer platform. The decision between them is not about which device is "better" in the abstract; it is about whether the buyer wants to run the fitting procedure themselves or pay for ongoing remote adjustment.

Against cheaper self-fitting devices, the All-Day Clear's main distinction is the brand behind it and the app-based fitting Sennheiser publishes, rather than a feature no other self-fitting device has. A shopper comparing self-fitting options across price points should look at JVC's self-fitting device at $699.95 as the next tier down.

Because the All-Day Clear is rechargeable, it does not carry the recurring cost of disposable zinc-air cells the way a battery-powered aid does. Those cells come in a small number of universal sizes, such as size 312 or size 13, colour-coded and identical across every manufacturer, and a battery-powered device needs a fresh one every few days to two weeks depending on size and use. A rechargeable device removes that line item entirely.

What a rechargeable device adds instead is a cost most buyers do not think about at purchase: the internal battery is a wearable component that degrades with charge cycles over years of use, and its eventual replacement is a service item rather than a recurring consumable. Sennheiser does not publish a specific replacement interval or cost for that service in the specifications available here, so it is worth asking about before buying rather than assuming it is included indefinitely. See hearing aid battery sizes for how the disposable alternative compares, and the annual cost of ownership tool to estimate a specific device's running cost.
