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.
Choice

Sony CRE-E10
The Sony CRE-E10 is a mid-priced OTC hearing aid that earns an A grade with a SoundScore of 4.7/5, placing it in the top 3% of the 65 OTC hearing aids tested in our lab. At $998, this visible-in-ear style device delivers performance that competes with the best in its category. Speech performance is a standout strength. Speech in quiet scores a strong 4.3/5, sitting 1.46 points above the category average. Speech in noise reaches a solid 3.3/5, which is 1.77 points above average—a meaningful advantage for conversations in challenging environments. Music streaming quality is another highlight at 4.0/5, exceeding the category average by over 2 points, making it a strong choice for users who value audio fidelity when streaming from their iPhone. The device does have limitations. Own voice comfort scores a low 1.7/5, falling 0.81 points below the category average—users sensitive to the sound of their own voice may find this bothersome. Feedback handling is solid in absolute terms at 3.4/5 but sits 1.14 points below the category average, suggesting slightly less stability margin than many OTC competitors. The CRE-E10 is best suited for users who prioritize speech clarity and streaming quality and are less sensitive to own-voice perception. It has earned HearAdvisor's Expert's Choice Award for three consecutive years (2023–2025), reflecting its consistent strong performance in lab testing.
