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

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.

Zepp Clarity One
The Zepp Clarity One is a mid-priced OTC hearing aid with an invisible-in-ear design, priced at $699. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.9/5, ranking #23 among 65 OTC hearing aids tested—placing it in the top 34% of the category. This device demonstrates notable strengths in speech clarity during quiet environments, scoring 3.7/5—nearly a full point above the category average. Own-voice comfort is another highlight at 3.8/5, measuring 1.29 points above average, which suggests reduced occlusion effects that many users find bothersome with in-ear devices. Feedback handling is excellent at 5.0/5 in the tuned configuration. However, the Clarity One has significant limitations. Speech understanding in noisy environments scores just 1.4/5, slightly below the category average. Most notably, music streaming scored 0.0/5—nearly 2 points below the category average—indicating this device does not support audio streaming functionality, a feature some competitors in this price range offer. The Zepp Clarity One is best suited for users who prioritize clear speech in quieter settings and natural own-voice quality, and who do not need music or media streaming capabilities. Those seeking better noise performance or streaming features should consider alternatives, including options like the Olive Union Air, which offers similar overall sound quality at a lower price point.
