EargoSoundScore 3.1Grade B

Eargo SE

The Eargo SE is a premium-priced OTC hearing aid at $1,699, featuring an invisible-in-ear design and earning a B grade with a SoundScore of 3.1/5 in our lab testing. This places it in the top 85% of the OTC hearing aid category, ranking #56 of 65 devices tested. In our testing, the Eargo SE demonstrated solid performance in speech clarity for quiet environments, scoring 3.2/5—0.43 points above the category average. Feedback handling was excellent at 4.6/5, meaning users should experience stable performance without whistling issues. However, the device showed limitations in challenging listening situations, with speech in noise scoring 1.3/5, which falls 0.23 points below the category average. A notable weakness is the complete absence of music streaming capability, scoring 0.0/5 compared to the category average of 1.92/5. Own-voice comfort scored 2.4/5, slightly below the category average. These mixed results suggest the Eargo SE prioritizes its discreet form factor over comprehensive audio features. The Eargo SE may appeal to users who prioritize an invisible design and primarily need help hearing conversations in quieter settings. However, given its premium price point and the availability of alternatives like the Jabra Enhance Select 50R that deliver stronger overall scores at lower prices, value-conscious consumers may want to explore other options before committing.

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.
