Sennheiser All-Day Clear OTC Hearing Aids Review 2026: Budget-minded buyers who want a dedicated rechargeable OTC aid without an iPhone

Our verdict
Sennheiser All-Day Clear scores 7.1/10 in our 2026 OTC hearing aid ranking, and Firsthand earns nothing on it. FDA cleared the All-Day Clear and All-Day Clear Slim through 510(k) K230538 in June 2023 as self-fitting OTC hearing aids. At $999.95 per pair it is the cheapest dedicated device here, it is rechargeable with a quoted 16 hours of use with Bluetooth, and its app tunes sound using real conversation samples rather than tone tests. You get a 90-day trial. The weaker points: a 1-year warranty, no included audiologist sessions, and a product page that says 'FDA-approved' when the device was cleared through a different FDA pathway. We found no published trial of this model, so the evidence is the same class-level research that covers self-fitting aids in general. It fits buyers who want a standalone device at the lowest price and are comfortable fitting it themselves.

What the evidence says
- FDA's 510(k) database lists K230538, All-Day Clear Slim ADCS1 and All-Day Clear ADC1, applicant Sonova AG, classified as a Self-Fitting Air-Conduction Hearing Aid, Over The Counter, decision date June 16, 2023. (FDA 510(k) database: K230538)
- At 8 months, a follow-up of a randomized trial found no significant difference in self-reported benefit (APHAB, IOI-HA) between self-fit OTC aids and the same aids fitted by audiologists; several authors reported fees from the device maker. (De Sousa et al., JAMA Otolaryngol Head Neck Surg 2024, long-term outcomes (PubMed))
- FDA says OTC hearing aids are for adults 18+ with perceived mild to moderate hearing loss, have limited maximum output, and lists warning signs such as sudden or one-sided hearing loss that need a clinician. (FDA: OTC Hearing Aids: What You Should Know)
