In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.7/5, ranking #31 of 36 prescription hearing aids tested. This device demonstrates solid speech clarity in quiet environments, scoring 3.5/5—0.13 points above the category average.

Music streaming scored 2.8/5, slightly above average (+0.16 points) though still in mixed territory.

At this premium price point, competitors including the Phonak Sphere Infinio (5.0/5), Oticon Intent (4.85/5), and Oticon Real (4.75/5) deliver stronger overall sound performance. The Genesis AI may suit users who prioritize Starkey's ecosystem, hands-free calling features, and robust feedback control, but those seeking top-tier sound quality in this price range have higher-scoring alternatives to consider.
