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.

iHear MatriX
The iHear MatriX is a behind-the-ear OTC hearing aid priced at $499, earning a B grade with a SoundScore of 3.8/5 in our lab testing. This places it in the top 40% of OTC hearing aids, offering solid performance at a budget-friendly price point. In our testing, the MatriX demonstrated notable strengths in speech intelligibility. Speech in quiet scored a solid 4.0/5, measuring 1.17 points above the category average. Speech in noise performance came in at 2.4/5—above the category average by 0.96 points, though only mixed in absolute terms. Feedback handling was excellent at 5.0/5, surpassing the already-strong category average by 0.46 points, meaning users can expect reliable stability without whistling during typical wear. The most significant limitation is music streaming, which scored 0.0/5—a full 1.92 points below the category average. Users who prioritize streaming audio from their phone should consider alternatives. Own-voice comfort measured 2.7/5, slightly above category average but still mixed in absolute terms. The MatriX features rechargeable batteries and supports streaming from both iPhone and Android devices. With a normalized Initial Score of 3.7/5 improving to 4.3/5 after tuning, this hearing aid responds well to optimization. It's best suited for users who prioritize speech clarity and feedback-free wear over music streaming quality, and who want a budget OTC option that delivers above-average speech performance in our lab framework.
