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

Otofonix Encore
The Otofonix Encore is a behind-the-ear prescription hearing aid priced at $295, placing it in the budget tier of the prescription category. In our lab testing, it earned a C grade with a SoundScore of 2.7/5, ranking 35th out of 36 prescription hearing aids tested. Sound performance presents significant challenges across most metrics. Speech clarity scores are low in both quiet (1.0/5) and noisy environments (1.0/5), falling 2.32 and 0.96 points below category averages respectively. Music streaming capability is essentially absent at 0.0/5, and own-voice comfort is notably limited at 0.1/5 in the tuned configuration—2.65 points below the category average. The one bright spot is feedback handling, which scores an excellent 4.7/5. While this falls just 0.01 points below the category average, it represents strong absolute performance that should minimize whistling issues during daily use. This device runs on disposable batteries. At this price point, shoppers should be aware that the RxEars Rxi offers substantially better sound performance (4.09/5) in the same price range. The Otofonix Encore may suit budget-conscious consumers who prioritize feedback stability over speech clarity and streaming features, but our testing suggests most users would benefit from considering higher-performing alternatives within this price tier.
Choice

Signia Styletto AX
The Signia Styletto AX is a premium prescription behind-the-ear hearing aid released in 2022, priced at $4,398. In HearAdvisor's lab testing, it earns an A grade with a SoundScore of 4.3/5, ranking #19 among 36 prescription hearing aids tested. This device demonstrates strong speech-in-quiet performance at 4.0/5, scoring 0.71 points above the category average. Speech-in-noise shows mixed absolute results at 2.3/5, though this still sits 0.32 points above the category average of 1.96/5. Music streaming quality is solid at 3.1/5, exceeding the category average by 0.46 points—a meaningful advantage for users who frequently stream audio from their iPhone. Own-voice comfort scores a solid 3.0/5, slightly above category average. However, feedback handling at 3.9/5 falls 0.81 points below the category average of 4.71/5—solid in absolute terms but notably weaker than many prescription competitors in our testing. The Styletto AX has earned HearAdvisor's Expert's Choice Award in both 2023 and 2024. With its distinctive slim design, rechargeable batteries, and iPhone streaming capabilities, it may appeal to users prioritizing aesthetics and convenience alongside strong speech clarity in quieter environments. Those frequently in challenging noise situations or requiring maximum feedback stability may want to compare alternatives in this price tier.
