EargoSoundScore 3.3Grade B

Eargo 8

The Eargo 8 is a premium-priced OTC hearing aid ($2,399) that earns a B grade with a SoundScore of 3.3/5 in our lab testing. This invisible-in-ear device represents Eargo's 2025 flagship offering, featuring a rechargeable design that sits completely within the ear canal. In our testing, the Eargo 8 showed mixed performance across key metrics. Speech clarity in quiet environments is a relative strength, scoring 0.27 points above the OTC category average. Own-voice comfort also performs well, measuring 0.69 points above average at 3.2/5—a solid result that suggests reduced occlusion effects during conversation. However, speech understanding in noisy environments scored 1.2/5, which is both low in absolute terms and 0.27 points below the category average. The most significant limitation we measured was music streaming, which scored 0.0/5—nearly 2 points below the OTC average. This makes the Eargo 8 unsuitable for users who prioritize streaming audio quality. Feedback handling is strong in absolute terms at 4.2/5, though slightly below the category average. At its premium price point, the Eargo 8 faces stiff competition. Several devices in our database deliver comparable or better sound performance at lower prices, including alternatives from Eargo's own lineup. The Eargo 8 is best suited for users who prioritize invisible cosmetics and own-voice comfort over streaming capability and value, and who primarily need help hearing speech in quieter settings.

SigniaSoundScore 4.3Grade A

Signia Pure Charge&Go MaX

The Signia Pure Charge&Go MaX is a behind-the-ear prescription hearing aid released in 2026 that earns an A grade with a SoundScore of 4.3/5 in HearAdvisor's lab testing. This strong overall performance reflects solid results across key listening scenarios, with particular strengths in own-voice comfort and speech understanding in noisy environments. In our testing, the Pure Charge&Go MaX demonstrated notable advantages over the prescription hearing aid category average. Own-voice comfort scored 1.00 points above the category average at 3.7/5, suggesting effective management of occlusion-related issues that many hearing aid users find bothersome. Speech in noise performance measured 0.65 points above average at 2.8/5—above the category average, but only mixed in absolute terms, indicating room for improvement in the most challenging listening situations. Speech in quiet scored a solid 3.6/5, landing 0.24 points above the category average. Music streaming measured 2.9/5, slightly above average but mixed in absolute terms. Feedback handling scored an excellent 4.6/5 in absolute terms, though this fell 0.12 points below the category average of 4.72/5, reflecting the generally strong feedback control across modern prescription devices. The device showed meaningful improvement from initial to tuned fitting, with the normalized score rising from 4.2/5 to 4.6/5 after professional adjustment. This suggests that working with a hearing care professional to optimize settings can unlock additional performance, particularly for speech understanding. The Pure Charge&Go MaX appears well-suited for users who prioritize natural own-voice quality and improved conversation clarity in moderately noisy settings.
