Sony CRE-C10
The Sony CRE-C10 is a mid-priced OTC hearing aid at $798 that earns an A grade with a SoundScore of 4.0/5 in HearAdvisor's lab testing. This invisible-in-ear device ranks #13 among 63 OTC hearing aids tested, placing it in the top 19% of its category. Speech performance is the CRE-C10's standout strength. In our lab testing, speech in quiet scores a strong 4.4/5, which is 1.76 points above the OTC category average. Speech in noise also performs well at 3.1/5—a solid score that sits 1.97 points above the category average of just 1.13/5. These results suggest the device delivers meaningful speech clarity benefits in everyday listening situations. The CRE-C10 has notable limitations to consider. Music streaming scores 0.0/5, falling 1.93 points below the category average—this device is not designed for audio entertainment. Feedback handling is solid in absolute terms at 3.5/5, though it sits 1.03 points below the category average of 4.53/5. Own-voice comfort scores a mixed 2.6/5, which is slightly above average for the category but may feel less natural than some alternatives. This two-time Expert's Choice Award winner (2023, 2024) uses disposable batteries and offers a discreet, invisible-in-ear form factor. The CRE-C10 is best suited for consumers who prioritize speech clarity over streaming features and prefer a nearly invisible hearing solution. Buyers seeking music streaming or a lower price point may want to consider alternatives in this price range.

Sony CRE-C20
The Sony CRE-C20 is a mid-priced OTC hearing aid at $999 that earned a B grade with a SoundScore of 3.7/5 in our lab testing, ranking #21 of 63 devices in the OTC category. This invisible-in-ear design prioritizes discretion with its compact form factor and rechargeable batteries. Speech performance is where the CRE-C20 truly stands out. Speech in quiet scored an excellent 4.7/5, a full 2.06 points above the category average. Speech in noise also performed well at 3.2/5, more than 2 points above the typical OTC device. These results suggest strong amplification and processing for conversational clarity across varying listening environments. However, the CRE-C20 has notable limitations. Music streaming scored 0.0/5, falling 1.93 points below the category average—meaning audio streaming from phones is essentially unusable for music enjoyment. Feedback handling at 3.9/5 is solid in absolute terms, though it sits 0.63 points below the category average. Own-voice comfort scored 2.9/5, slightly above average but still mixed in absolute quality. The CRE-C20 is best suited for users who prioritize speech clarity and discreet appearance over streaming capabilities. Within the same price range, alternatives like the Sony CRE-E10 (5.0/5) or Lexie B2 Plus (4.48/5) offer stronger overall performance, making them worth considering if streaming or higher scores are priorities.
