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.

ZeppSoundScore 3.9Grade B

Zepp Clarity One

The Zepp Clarity One is a mid-priced OTC hearing aid with an invisible-in-ear design, priced at $699. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.9/5, ranking #23 among 65 OTC hearing aids tested—placing it in the top 34% of the category. This device demonstrates notable strengths in speech clarity during quiet environments, scoring 3.7/5—nearly a full point above the category average. Own-voice comfort is another highlight at 3.8/5, measuring 1.29 points above average, which suggests reduced occlusion effects that many users find bothersome with in-ear devices. Feedback handling is excellent at 5.0/5 in the tuned configuration. However, the Clarity One has significant limitations. Speech understanding in noisy environments scores just 1.4/5, slightly below the category average. Most notably, music streaming scored 0.0/5—nearly 2 points below the category average—indicating this device does not support audio streaming functionality, a feature some competitors in this price range offer. The Zepp Clarity One is best suited for users who prioritize clear speech in quieter settings and natural own-voice quality, and who do not need music or media streaming capabilities. Those seeking better noise performance or streaming features should consider alternatives, including options like the Olive Union Air, which offers similar overall sound quality at a lower price point.
