Eargo 8  Hero
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.

iBstoneSoundScore 3.6Grade B

iBstone AuraLink

The iBstone AuraLink is a mid-priced OTC hearing aid released in 2024, earning a B grade with a SoundScore of 3.6/5 in our lab testing. At $649, it ranks #33 of 65 OTC hearing aids tested, placing it in the top 49% of its category. This behind-the-ear device demonstrates a distinctive performance profile with notable strengths in specific areas. Music streaming stands out as a clear highlight, scoring 3.6/5—a solid result that lands 1.68 points above the OTC category average. Feedback handling is excellent at 5.0/5, exceeding the already-high category average by 0.46 points. Own-voice comfort scores 2.7/5, slightly above the category average but only mixed in absolute terms. The AuraLink's limitations appear in speech clarity metrics. Speech in quiet scores 2.3/5, falling 0.47 points below the category average—a mixed result that may affect conversational understanding in calm environments. Speech in noise presents a more significant challenge at 1.0/5, which is 0.48 points below the category average and low in absolute terms. This hearing aid may appeal most to users who prioritize music listening and phone streaming over speech clarity in challenging environments. However, budget-conscious shoppers should note that alternatives like the iHear MatriX offer higher scores at lower prices. The AuraLink's strength in feedback stability and streaming audio quality represents a specific value proposition for users whose priorities align with these capabilities.
