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.

The Lexie B3 is a mid-priced OTC hearing aid available at $999 that achieves an A grade with a SoundScore of 4.7/5 in our lab testing, ranking #1 among 65 OTC hearing aid devices tested. This behind-the-ear style device delivers category-leading performance across multiple metrics. Speech clarity is a standout strength.

Speech in noise performance scores 2.5/5—above the category average by 1.02 points, though only mixed in absolute terms at 2.5/5. This pattern reflects the broader challenge OTC devices face in noisy environments while still positioning the B3 as a top performer relative to its category. Music streaming quality is solid at 3.3/5, outperforming the category average by 1.38 points. Own-voice comfort scores a solid 3.0/5, sitting 0.49 points above average.
