Choice

Sennheiser All Day Clear
The Sennheiser All Day Clear is a mid-priced OTC hearing aid that earns an A grade with a SoundScore of 4.4/5, placing it in the top 8% of the OTC category and ranking #6 among 65 tested devices. At $949, this behind-the-ear device delivers strong overall performance that stands out in a crowded market. In our lab testing, the All Day Clear excels in speech clarity for quiet environments, scoring 4.0/5—a strong result that sits 1.25 points above the category average. Music streaming quality is another highlight, with a solid 3.3/5 score that's 1.38 points above average, making it one of the better choices for users who value audio fidelity beyond speech. Feedback handling is excellent at 5.0/5, meaning users should experience minimal whistling issues. The device shows more modest performance in challenging listening situations. Speech in noise scores 1.9/5, which is above the category average by 0.39 points but low in absolute terms—a common limitation across OTC devices. Own voice comfort is mixed at 2.5/5, essentially matching the category average. Best for: Consumers seeking a reliable OTC option with strong speech clarity in everyday quiet-to-moderate environments and quality music streaming. Those frequently in noisy settings may find the speech-in-noise performance limiting, though this reflects broader OTC category constraints rather than a specific weakness of this device.

Sontro Soundwave
The Sontro Soundwave is a mid-priced OTC hearing aid priced at $849, earning a B grade with a SoundScore of 3.1/5 in HearAdvisor's lab testing. This behind-the-ear device uses disposable batteries and ranks #61 of 65 OTC hearing aids tested, placing it in the top 92% of its category. In our lab testing, the Soundwave shows a notable strength in own-voice comfort, scoring 3.6/5—a solid result that sits 1.09 points above the category average. This suggests users may experience less of the "talking in a barrel" sensation that can occur with some hearing aids. However, the device faces challenges in other key areas. Speech in quiet scores 2.7/5 (mixed, 0.12 points below average), while speech in noise registers at 1.2/5 (low, 0.28 points below average), indicating potential difficulty in challenging listening environments. The most significant limitations appear in music streaming and feedback handling. Music streaming scores 0.0/5, falling 1.92 points below the category average—a notable weakness for users who value audio entertainment. Feedback handling scores 2.5/5, which is 2.04 points below the category average of 4.54/5, suggesting the device may be more prone to whistling issues. At this price point, competitors offer substantially stronger performance. Devices like the Sony CRE-E10 and Lexie B2 Plus deliver significantly higher sound scores in the same price range. The Sontro Soundwave may suit those prioritizing own-voice comfort over speech clarity and streaming quality, but most users would benefit from exploring higher-performing alternatives at similar or lower prices.
