HSKLock Hearing Aid
The HSKLock Hearing Aid is a budget-priced amplification product available for $69, earning a B grade with a SoundScore of 3.0/5 in our lab testing. This behind-the-ear device uses disposable batteries and ranks #5 of 8 amplification products tested. In our testing, the HSKLock delivered excellent feedback handling at 5.0/5, scoring 0.72 points above the category average. This means users can expect stable performance without whistling during typical wear. Own-voice comfort scored 2.8/5, slightly above the category average but only mixed in absolute terms. However, speech clarity presents significant limitations. Speech in quiet scored 1.5/5, falling 0.63 points below the category average, while speech in noise measured 1.0/5, which is 0.37 points below average. Music streaming scored 0.0/5, well below the already-low category average of 1.16/5, making this device unsuitable for audio entertainment purposes. The HSKLock may appeal to budget-conscious consumers seeking basic amplification with reliable feedback control. Those prioritizing speech understanding or music quality should consider alternatives. At this price point, competitors like the Autiphon U0 Series offer similar overall performance, though each device has distinct trade-offs in specific metrics.

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.
