At $315, this visible-in-ear style device ranks #9 among 65 OTC hearing aids tested, placing it in the top 12% of the category.

Music streaming quality is similarly impressive at 3.1/5, which is 1.18 points above the category average and represents solid performance for this price tier. Speech understanding in noisy environments scores 1.8/5, which is above the category average of 1.48/5, though still low in absolute terms—a common challenge across OTC devices. Own-voice comfort scores 2.9/5, above the category average by 0.39 points, though only mixed in absolute terms. Feedback handling is strong at 4.2/5, though slightly below the category average of 4.54/5. The device uses a closed vented dome coupling with an integrated receiver design. The Elehear Delight is well-suited for budget-conscious consumers seeking a capable OTC hearing aid with particular strengths in quiet conversation and audio streaming. Those who frequently encounter challenging noise environments may want to consider whether the modest speech-in-noise performance meets their needs.

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.
