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.

Linner Mars Hero
LinnerSoundGrade B

Linner Mars

The Linner Mars is a budget-priced OTC hearing aid released in 2023, earning a B grade with a SoundScore of 3.2/5 in our lab testing. At $399, it falls in the lower price tier of the OTC category but ranks #55 of 65 OTC devices tested, placing it in the bottom 17% of its category. This visible-in-ear device presents a mixed performance profile with notable strengths and significant weaknesses. Music streaming is a standout feature, scoring an excellent 4.6/5—a full 2.68 points above the category average. Feedback handling is also excellent at 5.0/5, meaning users can expect stable performance without whistling during normal use. However, speech clarity presents challenges. Speech in quiet scores a low 1.9/5, falling 0.85 points below the category average. Speech in noise performance is particularly limited at 1.0/5, sitting 0.46 points below average. Own-voice comfort also scores low at 1.0/5, which is 1.51 points below the category average—users may notice their own voice sounding unnatural or boomy. The Linner Mars may suit budget-conscious consumers who prioritize music and media streaming over speech understanding in challenging environments. However, buyers seeking better speech performance should consider alternatives like the Elehear Beyond or Apple AirPods Pro 2, which offer stronger overall sound scores in the same price range.
