Oticon More

The Oticon More is a premium behind-the-ear prescription hearing aid that earned an A grade with a SoundScore of 4.6/5 in our lab testing, placing it in the top 22% of the 36 prescription hearing aids we've evaluated. Released in 2021, this device remains competitive and has received HearAdvisor's Expert's Choice Award in both 2023 and 2024. In our testing, the Oticon More demonstrated strong speech clarity performance. Speech in quiet scored 4.0/5, which is 0.73 points above the category average—a notable margin that reflects genuine audibility advantages in everyday conversations. Speech in noise measured 2.7/5, which is above the category average by 0.75 points, though only mixed in absolute terms, meaning challenging listening environments may still require effort. Own-voice comfort scored a solid 3.1/5 (+0.35 vs category average), and music streaming measured 3.0/5 (+0.36 vs category average), both performing above typical prescription aids. Feedback handling scored 3.5/5, which is solid in absolute terms, though below the category average of 4.71/5 by 1.21 points—something to discuss with your hearing care provider. At $4,598, this is a premium-priced device offering iPhone and Android streaming, hands-free calling, and your choice of rechargeable or disposable batteries. The Oticon More is well-suited for those prioritizing speech clarity who want a proven performer from an established manufacturer. Competitors in this price range include the newer Oticon Intent (4.85/5) and Oticon Real (4.75/5), which may be worth comparing during your fitting appointment.

Sennheiser All-Day Clear Slim

The Sennheiser All-Day Clear Slim is a premium behind-the-ear OTC hearing aid priced at $1,499, earning an A grade with a SoundScore of 4.1/5 in our lab testing. This places it in the top 23% of the OTC hearing aid category, ranking #16 among 65 tested devices. In our testing, the All-Day Clear Slim demonstrates notable strengths in music streaming, scoring 3.8/5—a solid result that sits 1.88 points above the category average. This makes it one of the stronger performers for users who prioritize audio quality when streaming from their phone. Feedback handling is excellent at 5.0/5, measuring 0.46 points above the category average, meaning users can expect stable performance without whistling during typical daily activities. Speech clarity in quiet environments is solid at 3.6/5, coming in 0.85 points above the category average. However, speech in noise performance is low at 1.5/5, matching the category average—a common limitation across OTC devices. Own-voice comfort scores 1.9/5, which is 0.61 points below the category average, suggesting some users may notice their own voice sounds different or hollow. The All-Day Clear Slim includes rechargeable batteries and supports streaming to both iPhone and Android devices with hands-free functionality. At its price point, alternatives like the Lucid Tala and Audicus Omni 2 offer higher overall scores, though the Sennheiser may appeal to those who value the brand's audio heritage and prioritize music streaming quality over speech-in-noise performance.
