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

Audien Atom Pro 2
The Audien Atom Pro 2 is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.3/5 in our lab testing. Available for $289, this visible-in-ear device delivers solid performance in some areas while showing limitations in others. In our testing, the Atom Pro 2 demonstrated excellent feedback handling, scoring a perfect 5.0/5—0.46 points above the OTC category average. This means users can expect stable performance without whistling during typical daily activities. Own-voice comfort scored 2.6/5, slightly above the category average, suggesting acceptable naturalness when speaking. However, speech clarity presents a mixed picture. Speech in quiet scored 2.3/5 (0.49 points below category average), and speech in noise scored a low 1.3/5 (0.16 points below average). The most significant limitation is music streaming, which scored 0.0/5—nearly 2 points below the category average—indicating this device is not suitable for those who want to stream audio from their phone. At this price point, several alternatives offer stronger overall performance, including the Elehear Beyond and Apple AirPods Pro 2. The Atom Pro 2 may suit budget-conscious consumers who prioritize feedback-free operation over streaming capabilities and don't need maximum speech clarity. Those seeking better speech performance or any music streaming should consider higher-scoring options in this price range.

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.
