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 OTC hearing aid priced at $299, earning a B grade with a SoundScore of 3.3/5 in HearAdvisor's lab testing. This visible-in-ear style device ranks #50 of 65 OTC hearing aids tested, placing it in the top 75% of its category. In our testing, the Go Prime demonstrated excellent feedback handling, scoring a perfect 5.0/5—notably 0.46 points above the category average. This means users can expect stable performance without the whistling that can plague some hearing aids. Speech clarity in quiet environments measured at a mixed 2.7/5, slightly below the category average. Speech understanding in noisy situations scored low at 1.1/5, falling 0.39 points below average, suggesting this device may struggle in challenging listening environments like restaurants or social gatherings. The Go Prime's most significant limitation is its music streaming capability, which scored 0.0/5—nearly 2 points below the category average. Users who prioritize phone-streamed audio should consider alternatives. Own-voice comfort also scored low at 1.8/5, which may result in a "boomy" quality when speaking. At this price point, several competitors offer stronger overall performance, including the Elehear Beyond and Apple AirPods Pro 2. However, for budget-conscious consumers who primarily need basic amplification in quieter settings and value feedback-free operation, the Go Prime offers a functional entry point. The rechargeable batteries add convenience for daily use.

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.
