Go Hearing Go Prime vs Linner Mars
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.

Linner Mars
The Linner Mars is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.1/5 in our lab testing. At $399, it falls in the lowest price tier for OTC devices, though its overall sound performance ranks #55 of 65 in the OTC Hearing Aid category. This device presents a stark contrast in performance across different listening situations. Music streaming is a genuine standout, scoring an excellent 4.6/5—well above the category average. Feedback handling also earns a perfect 5.0/5, meaning users shouldn't experience whistling or squealing issues. However, the Mars struggles significantly with its core hearing aid function: speech clarity. Speech in quiet scores just 1.9/5, and speech in noise drops to 1.0/5, both falling below category averages. Own-voice comfort is another weak point at 1.0/5, which is 1.51 points below the category average. Users may find their own voice sounds unnatural or boomy when wearing these devices. The tuned fit shows modest improvement over the initial fit (3.4/5 vs 3.1/5), primarily through better speech-in-quiet performance. The Linner Mars may appeal to budget-conscious consumers who prioritize music and media streaming over speech understanding. However, several competitors in the same price range—including the Elehear Beyond and Apple AirPods Pro 2—offer substantially better overall sound performance. Those seeking improved speech clarity should consider alternatives that score higher in that critical area.
