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.

Sennheiser All-Day Clear Slim
The Sennheiser All-Day Clear Slim is a premium OTC behind-the-ear hearing aid priced at $1,499, earning an A grade with a SoundScore of 4.1/5. This places it in the top 23% of OTC hearing aids tested in our lab, ranking #16 among 65 devices in its category. This device excels in areas that reflect Sennheiser's audio heritage. Music streaming quality is a standout strength, scoring 3.8/5—a solid result that's 1.88 points above the OTC category average. Feedback handling is excellent at 5.0/5, meaning users can expect stability without whistling during typical use. Speech in quiet environments also performs well at 3.6/5, sitting 0.85 points above average for the category. However, the All-Day Clear Slim shows limitations in other areas. Speech in noise scores 1.5/5, matching the category average but representing a low absolute score that may challenge users in noisy restaurants or group conversations. Own-voice comfort is below average at 1.9/5, which could affect how natural users sound to themselves during conversation. The All-Day Clear Slim is best suited for consumers who prioritize music streaming and media consumption alongside hearing support, and who spend more time in quieter environments. Those frequently navigating noisy social situations may want to compare against higher-ranked competitors in this price range, such as the Lucid Tala or Audicus Omni 2, which achieve stronger overall scores.
