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

Otofonix Helix
The Otofonix Helix is a behind-the-ear amplification product released in 2021, priced at $695. In HearAdvisor's lab testing, it earned a C grade with a SoundScore of 2.6/5, ranking #7 of 8 devices in the Amplification Product category. The Helix demonstrates one clear strength: excellent feedback handling at 5.0/5, which is 0.72 points above the category average. This means users are unlikely to experience whistling or squealing during typical use. However, the device shows significant limitations in other areas. Speech clarity scores are low in both quiet (1.0/5) and noisy (1.0/5) environments, falling below category averages by 1.11 and 0.37 points respectively. Own-voice comfort is notably weak at 0.3/5 in the tuned configuration, measuring 2.34 points below the category average. This suggests users may find their own voice sounds unnatural or boomy. Music streaming capability scored 0.0/5, indicating this device is not suitable for those who want to stream audio content. Consumers in this price range have substantially higher-performing alternatives available. The Sennheiser Conversation Clear Plus scores 4.04/5, while the HearingAssist Micro achieves 3.54/5. Those seeking similar performance at a lower price point might consider the Otofonix Encore or RCA Micro. The Helix may appeal to users who prioritize feedback-free amplification over speech clarity or streaming features, but most shoppers will find better value elsewhere in this category.
Choice

Signia Active Pro IX
The Signia Active Pro IX is a premium prescription hearing aid with a visible-in-ear design, priced at $3,199. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.6/5, ranking #8 among 39 prescription hearing aids tested. This device delivers strong speech clarity performance. Speech in quiet scores 4.3/5, which is +0.85 points above the category average—a notable strength for everyday conversations. Speech in noise measures 2.9/5, which is +0.74 points above the category average, though the absolute score reflects mixed performance in challenging listening environments. Own-voice comfort scores a solid 3.3/5, sitting +0.60 points above average, suggesting reasonable naturalness for wearers. Music streaming quality is mixed at 2.9/5, only slightly above the category average (+0.14 points). Feedback handling scores 3.4/5—solid in absolute terms but -1.32 points below the category average of 4.72/5, indicating this device may be more prone to feedback than typical prescription aids in our standardized tests. The Active Pro IX features rechargeable batteries and supports both iPhone and Android streaming with hands-free capability. It earned HearAdvisor's 2024 Expert's Choice Award. Buyers in this premium price tier should note that competitors like the Phonak Sphere Infinio and Oticon Intent score higher overall. Those seeking similar performance at lower cost may want to explore options like the Rexton Reach R-Li T80 at Costco.
