Nuance Audio Glasses

The Nuance Audio Glasses are a premium OTC hearing aid priced at $1,200, featuring an innovative hearing glasses form factor that integrates amplification technology directly into eyewear. In HearAdvisor's lab testing, they earned a B grade with a SoundScore of 3.9/5, ranking #20 among 65 OTC hearing aids tested. This unique design delivers standout performance in own-voice comfort, scoring an excellent 4.7/5—well above the category average by 2.19 points. Speech clarity in quiet environments is also a strength at 3.8/5, exceeding the category average by 1.05 points. Speech understanding in noisy situations scores 2.3/5, which is above the category average but only mixed in absolute terms. The glasses form factor comes with notable trade-offs. Music streaming scored 0.0/5, falling 1.92 points below the category average—a significant limitation for users who want to stream audio. Feedback handling at 2.0/5 is 2.54 points below the category average, indicating potential stability challenges in certain situations. The Nuance Audio Glasses are best suited for consumers who prioritize discretion and want hearing amplification without a traditional in-ear device. The excellent own-voice comfort makes them appealing for those sensitive to the "plugged up" feeling of conventional hearing aids. However, buyers seeking music streaming functionality or who are in the same price range should note that alternatives like the Lucid Tala (4.61/5) or Audicus Omni 2 (4.59/5) offer stronger overall sound performance.

Sony CRE-C20 Hero
SonySoundScore 3.5Grade B

Sony CRE-C20

The Sony CRE-C20 is a mid-priced OTC hearing aid with an invisible-in-ear design, available for $999. In our lab testing, it earned a B grade with a SoundScore of 3.5/5, ranking #37 of 65 OTC hearing aids tested. This device shows a notable split in performance. Speech clarity is a clear strength—speech in quiet scores 4.1/5, which is 1.33 points above the category average, and speech in noise scores 2.7/5, sitting 1.24 points above average despite being only mixed in absolute terms. These results suggest the CRE-C20 prioritizes conversational intelligibility in its tuning approach. However, the device has significant limitations. Music streaming scored 0.0/5, falling 1.92 points below the category average—a notable weakness for users who want to stream audio. Feedback handling is solid at 3.9/5, though it sits 0.64 points below the category average of 4.54/5. Own voice comfort is mixed at 2.9/5, slightly above the category average. The CRE-C20 responds well to adjustment, with the normalized score improving from 3.3/5 at initial fit to 4.2/5 when tuned—a 0.9-point gain. Buyers focused primarily on speech understanding in conversations may find value here, but those wanting music streaming or seeking the strongest overall OTC performance should note that several competitors in this price range, including the Sony CRE-E10 at 4.66/5, scored higher in our testing.
