SigniaSoundScore 4.3Grade A

Signia Pure Charge&Go MaX

The Signia Pure Charge&Go MaX is a behind-the-ear prescription hearing aid released in 2026 that earns an A grade with a SoundScore of 4.3/5 in HearAdvisor's lab testing. This strong overall performance reflects solid results across key listening scenarios, with particular strengths in own-voice comfort and speech understanding in noisy environments. In our testing, the Pure Charge&Go MaX demonstrated notable advantages over the prescription hearing aid category average. Own-voice comfort scored 1.00 points above the category average at 3.7/5, suggesting effective management of occlusion-related issues that many hearing aid users find bothersome. Speech in noise performance measured 0.65 points above average at 2.8/5—above the category average, but only mixed in absolute terms, indicating room for improvement in the most challenging listening situations. Speech in quiet scored a solid 3.6/5, landing 0.24 points above the category average. Music streaming measured 2.9/5, slightly above average but mixed in absolute terms. Feedback handling scored an excellent 4.6/5 in absolute terms, though this fell 0.12 points below the category average of 4.72/5, reflecting the generally strong feedback control across modern prescription devices. The device showed meaningful improvement from initial to tuned fitting, with the normalized score rising from 4.2/5 to 4.6/5 after professional adjustment. This suggests that working with a hearing care professional to optimize settings can unlock additional performance, particularly for speech understanding. The Pure Charge&Go MaX appears well-suited for users who prioritize natural own-voice quality and improved conversation clarity in moderately noisy settings.

SonySoundScore 3.5Grade B

Sony CRE-C20

The Sony CRE-C20 is a mid-priced OTC hearing aid with an invisible-in-ear design, available for $999. In our lab testing, it earned a B grade with a SoundScore of 3.5/5, ranking #37 of 65 OTC hearing aids tested. This device shows a notable split in performance. Speech clarity is a clear strength—speech in quiet scores 4.1/5, which is 1.33 points above the category average, and speech in noise scores 2.7/5, sitting 1.24 points above average despite being only mixed in absolute terms. These results suggest the CRE-C20 prioritizes conversational intelligibility in its tuning approach. However, the device has significant limitations. Music streaming scored 0.0/5, falling 1.92 points below the category average—a notable weakness for users who want to stream audio. Feedback handling is solid at 3.9/5, though it sits 0.64 points below the category average of 4.54/5. Own voice comfort is mixed at 2.9/5, slightly above the category average. The CRE-C20 responds well to adjustment, with the normalized score improving from 3.3/5 at initial fit to 4.2/5 when tuned—a 0.9-point gain. Buyers focused primarily on speech understanding in conversations may find value here, but those wanting music streaming or seeking the strongest overall OTC performance should note that several competitors in this price range, including the Sony CRE-E10 at 4.66/5, scored higher in our testing.
