Eargo 7
The Eargo 7 is a premium-priced OTC hearing aid at $2,550, earning a B grade with a SoundScore of 3.4/5 in our lab testing. This invisible-in-ear device ranks #38 of 65 OTC hearing aids tested, placing it in the top 57% of its category. In our testing, the Eargo 7 demonstrates solid speech clarity in quiet environments, scoring 3.1/5—0.33 points above the OTC category average. Own-voice comfort also performs above average at 2.9/5, which is +0.39 points versus typical OTC devices, though only mixed in absolute terms. However, speech understanding in noisy situations is a weakness, scoring just 1.0/5, which falls 0.44 points below the category average. The most notable limitation is music streaming, which scored 0.0/5 in our lab measurements—1.92 points below the OTC average. Feedback handling is solid at 3.8/5 in absolute terms, though this is 0.74 points below the category average of 4.54/5. The Eargo 7 may appeal to users prioritizing a completely invisible design who primarily need help with speech in quieter settings. However, given its premium price point, consumers should note that several lower-priced alternatives in our database achieved higher overall sound scores. Those who frequently stream music or struggle in noisy environments may want to explore other options.

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.
