Hear.com Horizon Go IX

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.

MDHearing Volt Hero
MDSoundGrade B

MDHearing Volt

The MDHearing Volt is a budget-priced prescription hearing aid available for $397, earning a B grade with a SoundScore of 3.1/5 in our lab testing. This behind-the-ear, rechargeable device ranks #32 of 36 prescription hearing aids tested, placing it in the top 86% of its category. In our standardized testing, the Volt demonstrates excellent feedback handling at 5.0/5, scoring 0.29 points above the category average. This represents a genuine strength, as the device remained stable under our challenge protocols without audible squealing or whistling. However, speech performance presents significant limitations: speech in quiet scored 1.8/5 (1.57 points below the category average of 3.32), while speech in noise scored 1.0/5 (0.96 points below the 1.96 average). Own-voice comfort measured 2.6/5, a mixed result that falls 0.15 points below the category average. Music streaming is notably limited at 0.0/5, scoring 2.64 points below the category average—users prioritizing phone streaming should consider alternatives. The Volt showed no improvement between Initial and Tuned fits, with both configurations yielding identical scores of 3.1/5. The MDHearing Volt may suit budget-conscious consumers who prioritize basic amplification and excellent feedback stability over speech clarity or streaming features. However, shoppers in this price range should note that alternatives like the RxEars Rxi offer substantially higher performance at similar pricing.
