Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

EarCentric EasyCharge
The EarCentric EasyCharge is a budget-priced prescription behind-the-ear hearing aid released in 2023, earning a C grade with a SoundScore of 2.7/5 in our lab testing. At $229, it sits at the entry level of the prescription hearing aid market. In our standardized testing, this device showed a significant performance gap compared to the prescription hearing aid category. Speech clarity scores were notably low, measuring 2.32 points below the category average in quiet environments and 0.96 points below average in noisy settings. Music streaming performance was similarly limited at 0.0/5, falling 2.64 points below average. Own-voice comfort scored 1.9/5, which is 0.85 points below the category norm. The EasyCharge's standout feature is its excellent feedback handling, scoring a perfect 5.0/5—0.29 points above the category average of 4.71. This means users are unlikely to experience whistling or squealing during everyday use. The device also offers convenient rechargeable batteries. Within the same budget price range, the RxEars Rxi achieves significantly stronger overall performance with a 4.09/5 SoundScore. Consumers prioritizing sound quality on a tight budget may find better value elsewhere, though the EasyCharge's feedback stability and rechargeable design could appeal to users with modest amplification needs who value convenience over maximum speech clarity.

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 represents an entry-level option in the amplification category. In our standardized testing, the HSKLock demonstrates excellent feedback handling at 5.0/5, scoring 0.72 points above the category average. This means users are unlikely to experience whistling or squealing during normal wear. Own-voice comfort scores 2.8/5, which is slightly above the category average but mixed in absolute terms—wearers may notice some occlusion effects when speaking. Speech performance presents significant limitations. Speech in quiet scores 1.5/5, falling 0.63 points below the category average, while speech in noise scores 1.0/5, sitting 0.37 points below average. These low absolute scores indicate limited benefit for understanding conversation in our test framework. Music streaming is not supported, scoring 0.0/5. The HSKLock ranks #5 of 8 amplification products tested, placing it in the top 50% of its category. At this price point, it may suit buyers seeking basic amplification with reliable feedback control, though those prioritizing speech clarity should consider the trade-offs carefully.
