HSKLock Hearing Aid vs RCA Micro
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

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.

RCA Micro
The RCA Micro is a budget-priced behind-the-ear OTC hearing aid released in 2023, earning a C grade with a SoundScore of 2.7/5 in our lab testing. At $399, it sits in the lowest price tier of the OTC category but ranks last among the 65 OTC hearing aids we've tested. In our standardized testing, the RCA Micro shows a significant performance gap compared to category peers. Speech understanding scores are notably low, with speech in quiet at 1.0/5 (1.79 points below the category average) and speech in noise also at 1.0/5 (0.48 points below average). Music streaming scored 0.0/5, falling 1.92 points below the category average—meaning phone audio streaming is essentially non-functional as a feature. The one bright spot is excellent feedback handling at 5.0/5, which is 0.46 points above the category average, indicating stable performance without whistling during normal use. Own-voice comfort is mixed at 2.1/5, sitting 0.41 points below the category average. This suggests wearers may notice some unnatural quality to their own voice during conversations. At this price point, several alternatives deliver substantially stronger performance. The Elehear Beyond, Apple AirPods Pro 2, and Zepp Clarity Omni all fall within the same price range while scoring significantly higher in our testing. The RCA Micro's rechargeable batteries and simple BTE design offer basic convenience, but consumers seeking meaningful speech clarity improvements should consider higher-performing options in this competitive budget segment.
