iHearSoundScore 3.8Grade B

iHear MatriX

The iHear MatriX is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.8/5, placing it in the top 40% of the OTC hearing aid category in our lab testing. At $499, this behind-the-ear device delivers solid speech performance that exceeds category averages, though with a notable tradeoff in streaming capabilities. Speech clarity is a clear strength for the MatriX. In quiet environments, it scores 4.0/5—a solid result that sits 1.17 points above the OTC category average. Speech in noise performance is more modest at 2.4/5, which is mixed in absolute terms but still 0.96 points above the typical OTC device. Feedback handling is excellent at 5.0/5, meaning users should experience minimal whistling during daily wear. The most significant limitation is music streaming, which scores 0.0/5—well below the category average of 1.92/5. While the MatriX supports both iPhone and Android streaming, audio fidelity for music is poor in our testing. Own-voice comfort is mixed at 2.7/5, roughly in line with category norms. The MatriX shows meaningful improvement with tuning, jumping from an Initial Score of 3.7/5 to a Tuned Score of 4.2/5. This suggests users who invest time in adjustment can unlock better performance. For budget-conscious buyers prioritizing speech understanding over music quality, the MatriX offers competitive value in its price range, though alternatives like the Elehear Beyond score higher overall at similar pricing.

OliveSoundScore 3.9Grade B

Olive Union Air

The Olive Union Air is a budget-priced OTC hearing aid that earned a B grade with a SoundScore of 3.9/5 in our lab testing, placing it in the top 31% of OTC hearing aids at #21 of 65 devices tested. At $250, it represents a competitive entry point in the over-the-counter hearing aid market. In our testing, this visible-in-ear style device demonstrated notable strengths in music streaming, scoring 3.6/5—a solid result that sits 1.67 points above the OTC category average. Feedback handling was excellent at 5.0/5, meaning users should experience minimal whistling or squealing during normal use. Speech understanding in quiet environments also performed well at 3.3/5, measuring 0.46 points above the category average. The Olive Union Air does show limitations in more challenging listening situations. Speech in noise scored 1.0/5, falling 0.48 points below the category average—a common weakness among budget OTC devices that may affect conversations in restaurants or busy environments. Own-voice comfort measured 2.2/5, slightly below average, which some users may notice when speaking. This device is best suited for individuals who prioritize music and media streaming, need reliable feedback control, and primarily listen in quieter environments. Those who frequently encounter noisy social situations may want to consider devices with stronger speech-in-noise performance.
