Eargo 6

The Eargo 6 is a premium-priced OTC hearing aid ($2,250) that earns a B grade with a SoundScore of 3.4/5 in our lab testing. This invisible-in-ear device ranks #42 of 65 OTC hearing aids tested, placing it in the top 63% of its category. In our standardized testing, the Eargo 6 demonstrates solid speech clarity in quiet environments, scoring 3.3/5—notably 0.53 points above the OTC category average. Own-voice comfort also performs above category average at 2.9/5, which may benefit users sensitive to the sound of their own voice. However, the device shows limitations in challenging listening situations, with speech-in-noise performance scoring 1.0/5, falling 0.48 points below the category average. A significant limitation is music streaming, which scores 0.0/5—well below the category average by 1.92 points. Users who prioritize streaming audio content should consider alternatives. Feedback handling scores 3.3/5, which is solid in absolute terms though 1.24 points below the category average of 4.54/5. The Eargo 6 may appeal to users prioritizing a completely invisible form factor and solid quiet-environment performance. However, at its premium price point, alternatives like the Sony CRE-C10 offer stronger overall performance at a lower price. The rechargeable battery adds convenience, but buyers should weigh the device's limitations in noise and streaming against its aesthetic benefits.

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.
