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

Otofonix Groove
The Otofonix Groove is a behind-the-ear prescription hearing aid priced at $795, earning a C grade with a SoundScore of 2.7/5 in our lab testing. This rechargeable BTE device ranks 36th out of 36 tested prescription hearing aids, placing it in the bottom tier of its category. In our testing, the Groove demonstrated one clear strength: excellent feedback handling at 5.0/5, scoring 0.29 points above the category average. The device remained stable during our standardized challenge motions with no audible feedback issues. However, speech performance was significantly limited, with both speech in quiet and speech in noise scoring 1.0/5—falling 2.32 and 0.96 points below their respective category averages. Music streaming quality scored 0.0/5, which is 2.64 points below the prescription category average. Own-voice comfort was also low at 0.4/5 in the tuned configuration, 2.35 points below average, suggesting notable occlusion-related concerns. The normalized Initial Score of 2.7/5 and Tuned Score of 2.6/5 indicate that professional fitting adjustments did not improve overall performance. Given its positioning at the bottom of the prescription hearing aid category and the availability of lower-priced alternatives that scored higher in our testing, the Otofonix Groove may be difficult to recommend for most users seeking balanced sound quality across listening situations.
Choice

Resound Nexia
The Resound Nexia is a premium behind-the-ear prescription hearing aid released in 2023, priced at $4,298. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.0/5, ranking #26 of 36 devices in the Prescription Hearing Aid category. The Nexia demonstrates clear strengths in specific performance areas. Feedback handling is excellent at 5.0/5, scoring 0.29 points above the category average—meaning users can expect reliable stability without whistling during typical daily activities. Own-voice comfort is also a highlight at 3.6/5, measuring 0.85 points above average, which may appeal to those bothered by their voice sounding hollow or boomy in other devices. However, the Nexia shows meaningful limitations in challenging listening environments. Speech in noise performance is low at 1.0/5, falling 0.96 points below the category average of 1.96/5. Speech in quiet scores 3.2/5—solid in absolute terms, though 0.11 points below the category average. Music streaming is mixed at 2.8/5, slightly above average but not a standout. At this price point, several alternatives in the same range deliver stronger overall performance, including the Phonak Sphere Infinio and Oticon Intent. The Nexia may be best suited for users who prioritize own-voice comfort and feedback-free performance over speech clarity in noisy environments, and who value the Resound ecosystem's connectivity features including iPhone and Android streaming with hands-free capability.
