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

HearingAssist Control
The HearingAssist Control is a mid-priced OTC behind-the-ear hearing aid available at $549. In our lab testing, it earned a B grade with a SoundScore of 3.3/5, placing it in the top 77% of OTC hearing aids tested. This device demonstrates solid speech performance, scoring above the category average in both quiet and noisy environments. Speech in quiet earned a solid 3.4/5, while speech in noise scored 2.0/5—above average for the category but only mixed in absolute terms. Feedback handling is excellent at 5.0/5, meaning wearers should experience minimal whistling during normal use. The HearingAssist Control has notable limitations. Music streaming scored 0.0/5, indicating this device does not support audio streaming functionality—a significant gap compared to many competitors in this price range. Own-voice comfort scored 2.1/5, which is below the category average and may result in a hollow or boomy perception of your own voice. For shoppers considering this price tier, alternatives like the Yeasound RIC800 (4.73/5) and Sony CRE-E10 (4.66/5) offer substantially higher overall sound performance. The HearingAssist Control may suit buyers prioritizing speech clarity and feedback stability who don't need streaming capabilities, but most users would benefit from exploring higher-scoring options at similar price points.

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.
