Otofonix Helix vs Signia Active Pro IX
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 priced at $695, earning a C grade with a SoundScore of 2.7/5 in our lab testing. This places it in the lower tier of the amplification product category, ranking #7 of 8 devices tested. In our standardized testing, the Helix demonstrates one clear strength: excellent feedback handling, scoring a perfect 5.0/5—well above the category average. This means users can expect stable performance without whistling or squealing during normal wear and head movements. However, the Helix 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. Music streaming capability scored 0.0/5, indicating this device is not suitable for those who want to stream audio content. Own-voice comfort is also a weakness, particularly in the tuned configuration. At this price point, consumers should be aware that several alternatives in the same range offer stronger overall performance. The Otofonix Helix may appeal to those who prioritize feedback-free operation above other factors, but those seeking better speech understanding or streaming functionality should explore other options in the amplification product category.
Choice

Signia Active Pro IX
The Signia Active Pro IX is a premium prescription hearing aid with a visible-in-ear style, priced at $3,199. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.7/5, ranking #7 among 36 prescription hearing aids tested—placing it in the top 17% of its category. This 2024 release demonstrates particular strength in speech performance. Speech in quiet scored a strong 4.3/5, sitting 0.93 points above the category average. Speech in noise measured 2.9/5, which is above the category average by 0.89 points, though only mixed in absolute terms. Own-voice comfort scored a solid 3.3/5, exceeding the category average by 0.55 points. Feedback handling presents a more nuanced picture at 3.4/5—solid in absolute terms, though 1.31 points below the category average. Music streaming scored 2.9/5, slightly above the category average but mixed overall. The device features rechargeable batteries, iPhone and Android streaming, and hands-free calling capabilities. The Signia Active Pro IX is best suited for those prioritizing speech clarity who want a discreet earbud-style design. It earned HearAdvisor's Expert's Choice Award for 2024. Shoppers in this premium price tier may also consider the Phonak Sphere Infinio or Oticon Intent, which scored higher in our testing, or explore options like the Rexton Reach at Costco for similar performance at a lower price point.
