Uses Official HearAdvisor Lab Data
Eargo 8  Hero
EargoSoundGrade B

Eargo 8

The Eargo 8 is a premium-priced OTC hearing aid featuring an invisible-in-ear design with rechargeable batteries, priced at $2,399. In our lab testing, it earned a B grade with a SoundScore of 3.4/5, placing it in the top 71% of the OTC Hearing Aid category. Sound performance presents a mixed picture. The Eargo 8 delivers solid speech-in-quiet performance at 3.1/5, scoring 0.27 points above the category average—making it a reasonable choice for conversational settings without background noise. Own-voice comfort is another strength, measuring 0.69 points above average at 3.2/5, which may appeal to users who are sensitive to hearing their own voice through hearing aids. Feedback handling is strong in absolute terms at 4.2/5, though slightly below the category average. However, the device shows notable weaknesses in challenging listening environments. Speech-in-noise performance is low at 1.2/5, falling 0.27 points below the category average—users who frequently encounter noisy restaurants, busy offices, or social gatherings may find this limiting. Music streaming scored 0.0/5, significantly below the category average, making this device unsuitable for users who prioritize audio entertainment through their hearing aids. The Eargo 8 is best suited for users who prioritize discreet, invisible-in-ear styling and primarily need assistance in quieter conversational settings. However, at this premium price point, buyers should be aware that similarly-priced alternatives and even some lower-cost options may offer comparable or better overall sound performance.

Otofonix Groove Hero
OtofonixSoundGrade C

Otofonix Groove

The Otofonix Groove is a behind-the-ear prescription hearing aid priced at $795, earning a C grade with a SoundScore of 2.7/5 in our lab testing. This rechargeable BTE device ranks 36th out of 36 tested prescription hearing aids, placing it in the bottom tier of its category. In our testing, the Groove demonstrated one clear strength: excellent feedback handling at 5.0/5, scoring 0.29 points above the category average. The device remained stable during our standardized challenge motions with no audible feedback issues. However, speech performance was significantly limited, with both speech in quiet and speech in noise scoring 1.0/5—falling 2.32 and 0.96 points below their respective category averages. Music streaming quality scored 0.0/5, which is 2.64 points below the prescription category average. Own-voice comfort was also low at 0.4/5 in the tuned configuration, 2.35 points below average, suggesting notable occlusion-related concerns. The normalized Initial Score of 2.7/5 and Tuned Score of 2.6/5 indicate that professional fitting adjustments did not improve overall performance. Given its positioning at the bottom of the prescription hearing aid category and the availability of lower-priced alternatives that scored higher in our testing, the Otofonix Groove may be difficult to recommend for most users seeking balanced sound quality across listening situations.
