Otofonix Helix Hero
OtofonixSoundGrade C

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.

Starkey Evolv AI Hero
StarkeySoundGrade B

Starkey Evolv AI

The Starkey Evolv AI is a premium behind-the-ear prescription hearing aid released in 2022, currently available at $4,598. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.9/5, ranking #28 of 36 prescription hearing aids tested. This device shows notable strengths in specific performance areas. Music streaming quality stands out at 3.7/5, scoring 1.06 points above the category average—making it a solid choice for users who prioritize audio entertainment. Speech in noise performance reaches 2.8/5, which is 0.81 points above the category average, though the absolute score reflects mixed real-world performance in challenging listening environments. Speech in quiet is solid at 3.4/5, slightly above average. The Evolv AI does show weaknesses in two key areas. Own voice comfort scores 2.1/5, falling 0.65 points below the category average, which may affect how natural your own speech sounds. Feedback handling, while solid in absolute terms at 3.5/5, runs 1.21 points below the category average of 4.71/5—meaning competitors in this price tier generally offer better feedback suppression. At this premium price point, several alternatives deliver stronger overall performance, including the Phonak Sphere Infinio and Oticon Intent. However, the Evolv AI's Expert's Choice Award recognition in 2023 and 2024 reflects its practical strengths. This hearing aid may suit users who prioritize music streaming quality and improved speech understanding in noise over own-voice comfort, and who value Starkey's feature set including rechargeable batteries and hands-free calling for both iPhone and Android.
