Otofonix Helix vs Widex Moment
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

Widex Moment
The Widex Moment is a premium behind-the-ear prescription hearing aid that earns an A grade with a SoundScore of 4.6/5 in HearAdvisor's lab testing, placing it in the top 21% of the prescription hearing aid category. Currently available at $3,398, this 2022 release has earned Expert's Choice Awards in both 2023 and 2024. In our testing, the Moment demonstrates particular strength in speech clarity in quiet environments, scoring 4.4/5—a full 0.97 points above the category average. Music streaming quality is another highlight at 3.5/5, which is 0.74 points above average for prescription devices. Speech in noise performance scores 2.4/5, which is above the category average by 0.30 points, though mixed in absolute terms. Feedback handling presents an interesting picture: the Moment scores a strong 4.0/5 in absolute terms, though this falls 0.72 points below the category average of 4.72/5. Own-voice comfort is solid at 3.0/5, sitting 0.30 points above the category average. The Widex Moment is well-suited for users who prioritize natural sound quality and enjoy streaming music or podcasts from their devices. It supports both iPhone and Android streaming with hands-free capability, and features rechargeable batteries for convenience. While premium-priced competitors like the Phonak Sphere Infinio and Oticon Intent score higher overall, the Moment offers a compelling balance of performance across key listening scenarios.
