The Autiphon U0 Series is best suited for budget-conscious consumers who primarily need basic amplification in quieter settings and prioritize reliable, feedback-free operation over advanced features.

The Hear.com Horizon Go IX is a premium prescription behind-the-ear hearing aid released in 2024, listed at $6,500. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.4/5, ranking #17 among 36 prescription hearing aids tested. This device demonstrates particular strength in speech clarity. Speech in quiet scored a strong 4.0/5, which is +0.72 points above the category average. Speech in noise performance also exceeded the category average by +0.61 points, though at 2.6/5 the absolute score remains mixed—meaning it handles challenging listening environments better than many competitors but still has room for improvement in demanding situations. The most notable limitation is own-voice comfort, scoring 1.8/5—a low result that falls 0.95 points below the category average. Users sensitive to how their own voice sounds may find this particularly noticeable. Feedback handling is strong in absolute terms at 4.4/5, though it sits slightly below the category average by 0.31 points. Music streaming performance is mixed at 2.7/5, essentially matching the category average. At this price point, the Horizon Go IX faces stiff competition. Same-price alternatives like the Phonak Sphere Infinio (5.0/5) and Oticon Intent (4.85/5) deliver higher overall sound performance. Budget-conscious shoppers might also consider options like the Rexton Reach R-Li T80 at Costco, which achieves a higher score at a lower price. The Horizon Go IX is best suited for those prioritizing speech clarity who can accept the own-voice trade-off and prefer the hear.com service model.
