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 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.
Choice

Sony CRE-E10
The Sony CRE-E10 is a mid-priced OTC hearing aid available at $998 that delivers excellent overall performance, earning an A grade and a SoundScore of 4.7/5 in our lab testing. This places it at #3 among 65 OTC hearing aids tested—in the top 3% of its category. In our testing, the CRE-E10 excels where it matters most for everyday communication. Speech in quiet scores a strong 4.3/5, measuring 1.46 points above the category average. Speech in noise performance is solid at 3.3/5, a full 1.77 points above average—a meaningful advantage for challenging listening environments. Music streaming is a particular standout at 4.0/5, scoring 2.08 points above the category average, making this an appealing choice for users who value audio quality beyond speech. The device does have limitations worth noting. Own-voice comfort scores low at 1.7/5, falling 0.81 points below the category average—users may notice their own voice sounds different or hollow. Feedback handling is solid in absolute terms at 3.4/5 but sits 1.14 points below the category average, so some users may experience occasional whistling in certain situations. The CRE-E10 is best suited for consumers who prioritize speech clarity and streaming quality and are comfortable with a visible in-ear style. With rechargeable batteries, iPhone streaming, and hands-free capability, it offers modern convenience. This device has earned HearAdvisor's Expert's Choice Award for three consecutive years (2023-2025), reflecting its consistent top-tier performance among OTC options.
