Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Go Hearing Go Prime
The Go Hearing Go Prime is a budget-priced OTC hearing aid available for $299, earning a B grade with a SoundScore of 3.3/5 in our lab testing. This visible-in-ear style device with rechargeable batteries ranks #50 of 65 OTC hearing aids tested, placing it in the top 75% of its category. In our testing, the Go Prime delivered mixed results across performance metrics. Its standout strength is excellent feedback handling, scoring a perfect 5.0/5—0.46 points above the category average. This means users can expect stable amplification without whistling during typical daily activities. However, speech clarity showed more modest performance, with speech in quiet scoring 2.7/5 and speech in noise at 1.1/5, both falling slightly below category averages. The device's most significant limitation is music streaming, which scored 0.0/5 in our testing—nearly 2 points below the category average. Users who prioritize phone audio streaming for calls or media should consider alternatives. Own-voice comfort also scored low at 1.8/5, which may result in a "boomy" quality when speaking. At its $299 price point, the Go Prime faces stiff competition. Higher-scoring alternatives in the same price range include the Elehear Beyond (4.34/5) and Apple AirPods Pro 2 (4.04/5). Budget-conscious shoppers might also consider the Olive Union Max or Lucid Enrich Pro, which offer comparable or better sound scores at lower prices. The Go Prime may suit those who prioritize feedback-free amplification and don't need streaming functionality, but most buyers would benefit from exploring these alternatives.

Phonak Sphere Infinio
The Phonak Sphere Infinio is a premium behind-the-ear prescription hearing aid released in 2024, priced at $4,898. In our lab testing, it earned an A grade with a SoundScore of 5.0/5, placing it at #2 among 39 prescription hearing aids tested—within the top 3% of its category. The standout performance comes in speech clarity. Speech in noise scores an excellent 4.7/5, a remarkable 2.59 points above the category average of 2.11/5. Speech in quiet also impresses at 4.5/5, sitting 1.07 points above average. For anyone who struggles to follow conversations in restaurants, gatherings, or busy environments, this device delivers measurably superior intelligibility compared to most alternatives we've tested. Music streaming quality is strong at 4.0/5, exceeding the category average by 1.24 points—a meaningful advantage for users who value audio fidelity when streaming from phones. However, own-voice comfort is mixed at 2.3/5, falling 0.40 points below the category average, which may affect how natural your own speech sounds. Feedback handling, while solid in absolute terms at 3.6/5, sits 1.12 points below the category average of 4.72/5. The Sphere Infinio is best suited for users prioritizing exceptional speech understanding, particularly in challenging noise environments, and who are willing to invest at the premium tier. Those especially sensitive to own-voice quality or requiring maximum feedback stability may want to compare alternatives like the similarly-priced Oticon Intent or the lower-priced Phonak Audéo EON Sphere.
