Eargo 7
The Eargo 7 is a premium-priced OTC hearing aid at $2,550, earning a B grade with a SoundScore of 3.4/5 in our lab testing. This invisible-in-ear device ranks #38 of 65 OTC hearing aids tested, placing it in the top 57% of its category. In our testing, the Eargo 7 demonstrates solid speech clarity in quiet environments, scoring 3.1/5—0.33 points above the OTC category average. Own-voice comfort also performs above average at 2.9/5, which is +0.39 points versus typical OTC devices, though only mixed in absolute terms. However, speech understanding in noisy situations is a weakness, scoring just 1.0/5, which falls 0.44 points below the category average. The most notable limitation is music streaming, which scored 0.0/5 in our lab measurements—1.92 points below the OTC average. Feedback handling is solid at 3.8/5 in absolute terms, though this is 0.74 points below the category average of 4.54/5. The Eargo 7 may appeal to users prioritizing a completely invisible design who primarily need help with speech in quieter settings. However, given its premium price point, consumers should note that several lower-priced alternatives in our database achieved higher overall sound scores. Those who frequently stream music or struggle in noisy environments may want to explore other options.

Linner Nova Earbud
The Linner Nova Earbud is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.4/5 in HearAdvisor lab testing. At $299, it ranks #39 of 65 OTC hearing aids tested, placing it in the top 58% of its category. This device shows a distinctive performance profile with clear strengths and weaknesses. Music streaming is a standout at 4.5/5—an excellent score that sits 2.58 points above the category average. Feedback handling is equally impressive at 5.0/5, meaning users can expect stable performance without whistling during normal wear. These metrics suggest the Linner Nova excels as a streaming-capable earbud-style device. However, speech clarity metrics fall below category averages. Speech in quiet scores 2.1/5, which is 0.71 points below average and reflects mixed absolute performance. Speech in noise is low at 1.3/5, trailing the average by 0.19 points. Own-voice comfort is particularly challenged at 0.5/5—a low score that sits 2.01 points below the category average, meaning users may notice their own voice sounds unnatural or boomy. The Linner Nova Earbud may appeal to buyers who prioritize streaming audio quality and stable feedback-free wear over maximum speech benefit. Those seeking stronger speech clarity should consider alternatives in this price range like the Elehear Beyond (4.34/5) or Apple AirPods Pro 2 (4.04/5), which score higher overall.
