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.

Resound Nexia Hero
ResoundSoundScore 4.0Grade A

Resound Nexia

The Resound Nexia is a premium behind-the-ear prescription hearing aid released in 2023, currently available at $4,298. In HearAdvisor's lab testing, it earned a SoundScore of 4.0/5 and an A grade, ranking #28 of 39 prescription hearing aids tested. The Nexia demonstrates clear strengths in specific areas. Feedback handling is excellent at 5.0/5, scoring 0.28 points above the category average—users can expect stable performance without whistling during typical daily activities. Own-voice comfort also stands out at 3.6/5, a solid score that sits 0.90 points above average, suggesting wearers may find their own voice sounds more natural compared to many competitors. However, speech performance presents a more mixed picture. Speech in quiet measures 3.2/5—solid in absolute terms but 0.19 points below the category average. More notably, speech in noise scores just 1.0/5, falling 1.11 points below average. This represents a significant limitation for users who frequently encounter challenging listening environments like restaurants or group conversations. Music streaming scores 2.8/5, essentially matching the category average. At this price point, several alternatives deliver stronger overall performance. The Phonak Sphere Infinio, Oticon Intent, and Oticon Real all score notably higher while occupying the same premium tier. Budget-conscious buyers might also consider options like the Jabra Enhance Select 500 at a lower price point with competitive sound quality. The Nexia may be best suited for users who prioritize feedback stability and own-voice comfort over speech-in-noise performance.
