Own-voice comfort was mixed at 2.2/5, falling 0.50 points below average—something to discuss with your hearing care provider if natural voice quality is a priority. The Infinio 90 competes in a crowded premium segment. At this price point, alternatives like the Phonak Sphere Infinio (4.98/5) and Oticon Intent (4.83/5) achieved higher overall scores in our testing. Buyers seeking Phonak's ecosystem and strong speech-in-quiet performance may find the Infinio 90 appealing, though those prioritizing noise performance or own-voice comfort should compare options carefully with their provider.

The ReSound Vivia 9 60S microRIE is a premium prescription behind-the-ear hearing aid released in 2025, currently available at $3,798. In our lab testing, it earned a B grade with a SoundScore of 3.9/5, ranking #29 of 39 prescription hearing aids tested. This device shows a mixed performance profile. Its standout strength is own-voice comfort, scoring 3.4/5—a solid result that sits 0.70 points above the category average. Speech clarity in quiet environments also performs at category average with a score of 3.4/5. Feedback handling is strong in absolute terms at 4.2/5, though this falls 0.52 points below the category average, reflecting the high bar set by competing prescription devices. The Vivia 9's most notable weakness is speech understanding in noisy environments, where it scored just 1.1/5—a low result that trails the category average by 0.96 points. Music streaming performance is mixed at 2.6/5, sitting slightly below average. These limitations are worth considering given the premium price positioning. For listeners who prioritize comfortable own-voice perception and primarily encounter quieter listening situations, the Vivia 9 may be suitable. However, those frequently in challenging noise environments should note that several alternatives in this price range—including the Phonak Sphere Infinio and Oticon Intent—deliver stronger overall performance in our testing. Budget-conscious shoppers may also find comparable sound quality at lower price points with options like the Jabra Enhance Pro 20 at Costco.
