Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

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.

Otofonix Groove
The Otofonix Groove is a behind-the-ear prescription hearing aid priced at $795, earning a C grade with a SoundScore of 2.7/5 in our lab testing. This rechargeable BTE ranks #38 of 39 devices in the prescription hearing aid category, placing it in the bottom 5% of its class. In our testing, the Groove demonstrated excellent feedback handling at 5.0/5, scoring 0.28 points above the category average. This represents a genuine strength, with the device maintaining stability during our standardized challenge motions. However, speech performance was significantly limited, with speech in quiet scoring 1.0/5 (2.40 points below the category average of 3.40) and speech in noise also at 1.0/5 (1.11 points below average). Music streaming was not functional in our tests, scoring 0.0/5 against a category average of 2.76. Own-voice comfort also fell well below typical prescription hearing aid performance at 0.4/5, which is 2.30 points below the category average. At this price point, several lower-cost alternatives delivered stronger overall performance in our testing. Consumers seeking value in the prescription category may want to explore other options, though those requiring robust feedback control in a rechargeable BTE format may find the Groove's stability noteworthy despite its other limitations.
