Otofonix Groove

The Otofonix Groove is a behind-the-ear prescription hearing aid priced at $795, earning a C grade with a SoundScore of 2.7/5 in our lab testing. This rechargeable BTE device ranks 36th out of 36 tested prescription hearing aids, placing it in the bottom tier of its category. In our testing, the Groove demonstrated one clear strength: excellent feedback handling at 5.0/5, scoring 0.29 points above the category average. The device remained stable during our standardized challenge motions with no audible feedback issues. However, speech performance was significantly limited, with both speech in quiet and speech in noise scoring 1.0/5—falling 2.32 and 0.96 points below their respective category averages. Music streaming quality scored 0.0/5, which is 2.64 points below the prescription category average. Own-voice comfort was also low at 0.4/5 in the tuned configuration, 2.35 points below average, suggesting notable occlusion-related concerns. The normalized Initial Score of 2.7/5 and Tuned Score of 2.6/5 indicate that professional fitting adjustments did not improve overall performance. Given its positioning at the bottom of the prescription hearing aid category and the availability of lower-priced alternatives that scored higher in our testing, the Otofonix Groove may be difficult to recommend for most users seeking balanced sound quality across listening situations.

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 4.2/5, ranking #12 among 65 OTC hearing aids tested. This invisible-in-ear style device uses disposable batteries and offers discreet amplification for those seeking a nearly undetectable option. In our lab testing, the CRE-C10 demonstrates excellent speech clarity in quiet environments, scoring 4.5/5—a full 1.71 points above the category average. Speech in noise performance is above average at +1.39 points versus category peers, though at 2.9/5 it remains mixed in absolute terms. This makes the device well-suited for everyday conversations but potentially challenging in very noisy settings. The most significant limitation is music streaming, which scored 0.0/5—well below the category average. Users who prioritize phone audio streaming or music listening should consider alternatives. Feedback handling is solid at 3.5/5, though it falls 1.04 points below the category average. Own-voice comfort scored 2.6/5, roughly matching the category average. The Sony CRE-C10 is best suited for users who prioritize speech understanding and discretion over streaming capabilities. It has earned HearAdvisor's Expert's Choice Award in both 2023 and 2024. Competitors in this price range include the higher-scoring Sony CRE-E10 and Lexie B2 Plus, which may offer additional features worth comparing.
