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.

Otofonix Groove
The Otofonix Groove is a behind-the-ear prescription hearing aid priced at $795, earning a C grade with a SoundScore of 2.7/5 in our lab testing. This rechargeable BTE ranks #38 of 39 devices in the prescription hearing aid category, placing it in the bottom 5% of its class. In our testing, the Groove demonstrated excellent feedback handling at 5.0/5, scoring 0.28 points above the category average. This represents a genuine strength, with the device maintaining stability during our standardized challenge motions. However, speech performance was significantly limited, with speech in quiet scoring 1.0/5 (2.40 points below the category average of 3.40) and speech in noise also at 1.0/5 (1.11 points below average). Music streaming was not functional in our tests, scoring 0.0/5 against a category average of 2.76. Own-voice comfort also fell well below typical prescription hearing aid performance at 0.4/5, which is 2.30 points below the category average. At this price point, several lower-cost alternatives delivered stronger overall performance in our testing. Consumers seeking value in the prescription category may want to explore other options, though those requiring robust feedback control in a rechargeable BTE format may find the Groove's stability noteworthy despite its other limitations.
