At $315, it ranks #9 among 65 OTC hearing aids tested, placing it in the top 12% of its category. Speech clarity is a standout strength for this device.

Speech in noise performance is above the category average by 0.34 points, though the absolute score of 1.8/5 remains low—meaning challenging listening environments may still prove difficult. Music streaming quality is solid at 3.1/5, exceeding the category average by 1.18 points, making it a reasonable choice for audio enjoyment beyond speech. Feedback handling scores a strong 4.2/5 in absolute terms, though this falls 0.34 points below the category average of 4.54/5. Own-voice comfort scores 2.9/5, which is above the category average by 0.39 points but remains mixed in absolute terms—some users may notice their own voice sounds different than expected.

Those who frequently encounter noisy settings may find the device less capable, but for everyday conversation and media consumption, it performs well above typical OTC expectations at its price point.
