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.

Signia Silk Charge&Go IX
The Signia Silk Charge&Go IX is a premium prescription hearing aid featuring an invisible-in-ear design, currently available at $3,298. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.7/5, ranking #32 of 39 prescription hearing aids tested. This device demonstrates a notable strength in speech clarity for quiet environments, scoring an excellent 4.6/5—well above the category average by 1.22 points. Speech in noise performance is mixed at 2.2/5, though this still edges slightly above the category average. Feedback handling is strong at 4.3/5, providing reliable stability during typical wear, even if it falls just below the category average. The Silk Charge&Go IX has significant limitations to consider. Own-voice comfort scores low at 1.5/5, falling 1.20 points below the category average—a trade-off that may relate to the invisible form factor. Most notably, the device does not support music streaming, scoring 0.0/5 in that metric, which is 2.76 points below the category average. At this premium price point, several competitors deliver substantially higher overall performance, including the Phonak Sphere Infinio (4.98/5) and Oticon Intent (4.83/5). The Silk Charge&Go IX is best suited for users who prioritize an invisible, rechargeable design and primarily need clear speech understanding in quieter settings, while having minimal need for streaming audio content.
