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 Encore
The Otofonix Encore is a budget-priced prescription hearing aid available for $295, earning a C grade with a SoundScore of 2.7/5 in our lab testing. This behind-the-ear device ranks #37 of 39 in the Prescription Hearing Aid category, placing it in the bottom tier of its class. In our standardized testing, the Encore demonstrates one clear strength: excellent feedback handling at 4.7/5, which means users are unlikely to experience whistling or squealing during normal use. However, the device shows significant limitations in other areas. Speech intelligibility scores are low in both quiet (1.0/5) and noisy environments (1.0/5), falling 2.40 and 1.11 points below category averages respectively. Music streaming performance scored 0.0/5, indicating this device is not suitable for those who want to stream audio content. The Encore uses disposable batteries and comes in a traditional behind-the-ear style. Notably, our tuned fit testing showed a slight decrease in overall performance compared to the initial fit, with the normalized score dropping from 2.8/5 to 2.4/5. Own-voice comfort also declined substantially when moving to a more occluding coupling. At this price point, consumers may want to consider alternatives. The RxEars Rxi offers substantially better performance at a similar budget price point with a score of 4.07/5. The Otofonix Encore may appeal to buyers seeking a very low-cost entry into prescription hearing aids who prioritize feedback stability, but those needing reliable speech clarity or streaming capabilities should explore other options.
