FortellSoundScore 6.0Grade A

Fortell AI Hearing Aids

The Fortell AI Hearing Aids are a premium prescription behind-the-ear device priced at $6,800, earning an A grade with a SoundScore of 6.0/5 in HearAdvisor lab testing—an exceptional result that places this device at the top of the prescription hearing aid category. Speech performance is where the Fortell AI truly distinguishes itself. Speech in noise scores an outstanding 6.0/5, a full 3.89 points above the category average of 2.11/5—the kind of margin that represents a meaningful difference in challenging listening environments like restaurants or group conversations. Speech in quiet also excels at 4.6/5, sitting 1.20 points above the category average. Music streaming performs strongly at 4.2/5, coming in 1.44 points above average for the category. The device does have a notable limitation: own-voice comfort scores just 1.5/5, falling 1.20 points below the category average. This low absolute score suggests wearers may notice occlusion effects when speaking. Feedback handling is excellent at 4.8/5, essentially matching the category average. Best suited for: Users who prioritize understanding speech in difficult listening situations and value streaming quality, and who can tolerate potential own-voice occlusion. Given the premium price point, buyers should weigh whether the exceptional speech-in-noise performance justifies the investment compared to alternatives like the Oticon Intent or Oticon Zeal, which offer strong performance at lower price points.

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.
