Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Eargo 5
The Eargo 5 is a premium-priced OTC hearing aid ($1,450) featuring an invisible-in-ear design with rechargeable batteries. In our lab testing, it earned a B grade with a SoundScore of 3.6/5, placing it in the top 52% of the OTC hearing aid category. This device demonstrates solid performance for speech understanding in quiet environments, scoring 3.5/5—0.75 points above the category average of 2.79/5. Own-voice comfort also measures above average at 2.8/5 (+0.29 vs category), though this remains mixed in absolute terms. Feedback handling is strong at 4.2/5, providing reliable stability during wear. However, the Eargo 5 shows notable limitations in other areas. Speech in noise performance is low at 1.4/5, slightly below the category average. Most significantly, music streaming scored 0.0/5, falling 1.92 points below the category average—this device does not support audio streaming functionality. The invisible-in-ear form factor appeals to users prioritizing discretion, and the closed sleeve coupling remains consistent between initial and tuned fits. Tuning provided modest improvement, moving from a normalized Initial Score of 3.5/5 to a Tuned Score of 3.7/5. Given its premium price point, consumers may want to compare against alternatives like the Sony CRE-C10 or Nuance Audio Glasses, which offer similar or better sound performance at lower price points. The Eargo 5 is best suited for users who prioritize cosmetic discretion and primarily need help with speech in quieter settings.

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.
