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

HearingAssist Micro
The HearingAssist Micro is a premium amplifier in the invisible-in-ear style, priced at $698. In our lab testing, it earned a B grade with a SoundScore of 3.6/5, placing it #3 among the 8 amplification products we've tested. This device shows a clear strength in speech clarity during quiet environments, scoring 3.5/5—a solid result that sits 1.35 points above the category average of 2.11/5. Feedback handling is also strong at 4.0/5, though slightly below the category average of 4.28/5. Own-voice comfort comes in at 2.8/5, which is above the category average but only mixed in absolute terms. The Micro has notable limitations. Speech-in-noise performance is low at 1.1/5, falling 0.31 points below the category average. Music streaming is where this device struggles most significantly, scoring 0.0/5—well below the already modest category average of 1.16/5. Users who want to stream audio from their phone should look elsewhere. The HearingAssist Micro may suit those prioritizing discreet, invisible-in-ear design and clear speech understanding in quieter settings. However, buyers seeking strong noise management or any music streaming capability should consider alternatives. At this price point, the Sennheiser Conversation Clear Plus offers notably higher overall performance, while options like the iHear MatriX deliver similar sound quality at a lower price.
Choice

Sony CRE-E10
The Sony CRE-E10 is a mid-priced OTC hearing aid that earns an A grade with a SoundScore of 4.7/5, placing it in the top 3% of the 65 OTC hearing aids tested in our lab. At $998, this visible-in-ear style device delivers performance that competes with the best in its category. Speech performance is a standout strength. Speech in quiet scores a strong 4.3/5, sitting 1.46 points above the category average. Speech in noise reaches a solid 3.3/5, which is 1.77 points above average—a meaningful advantage for conversations in challenging environments. Music streaming quality is another highlight at 4.0/5, exceeding the category average by over 2 points, making it a strong choice for users who value audio fidelity when streaming from their iPhone. The device does have limitations. Own voice comfort scores a low 1.7/5, falling 0.81 points below the category average—users sensitive to the sound of their own voice may find this bothersome. Feedback handling is solid in absolute terms at 3.4/5 but sits 1.14 points below the category average, suggesting slightly less stability margin than many OTC competitors. The CRE-E10 is best suited for users who prioritize speech clarity and streaming quality and are less sensitive to own-voice perception. It has earned HearAdvisor's Expert's Choice Award for three consecutive years (2023–2025), reflecting its consistent strong performance in lab testing.
