Jabra Enhance Pro 20 at Costco
The Jabra Enhance Pro 20 at Costco is a behind-the-ear prescription hearing aid priced at $1,600, placing it in the premium tier. With a SoundScore of 4.0/5 and an A grade, it ranks #25 of 39 prescription hearing aids tested in our lab. In our testing, this device demonstrates notable strengths in own-voice comfort, scoring 3.5/5—0.80 points above the category average. This solid performance means wearers may find their own voice sounds more natural compared to many competitors. Feedback handling is excellent at 4.8/5, slightly above the category average, indicating reliable stability during movement and phone use. However, the Enhance Pro 20 shows limitations in challenging listening environments. Speech-in-noise performance scores just 1.1/5, falling 0.97 points below the category average—a significant gap that may affect conversations in restaurants, social gatherings, or other noisy settings. Speech-in-quiet is solid at 3.2/5 in absolute terms, though still 0.17 points below the category average. Music streaming scores 2.8/5, which is above the category average but only mixed in absolute terms. This device suits users who prioritize comfortable own-voice perception and excellent feedback control, and who spend most listening time in quieter environments. Those frequently navigating noisy situations may want to consider alternatives like the Rexton Reach R-Li T80 at Costco, which scored 4.56/5 in our testing. The Enhance Pro 20 includes rechargeable batteries, iPhone and Android streaming, and hands-free functionality.

Linner Mercury
The Linner Mercury is a budget OTC hearing aid priced at $387, earning a B grade with a SoundScore of 3.0/5 in our lab testing. This visible-in-ear style device ranks #60 of 65 in the OTC Hearing Aid category, positioning it in the lower tier of available options. In our standardized testing, the Mercury demonstrates excellent feedback handling at 4.7/5, scoring 0.16 points above the category average. This means users are unlikely to experience whistling or squealing during typical wear. However, the device shows limitations in other key areas. Speech in quiet scores 2.2/5, falling 0.62 points below the category average, while speech in noise performance is low at 1.0/5, sitting 0.48 points below average. Own-voice comfort is also low at 1.6/5, measuring 0.91 points below the category average. The most significant limitation is music streaming, which scores 0.0/5—a full 1.92 points below the category average. Users who plan to stream phone calls or music through their hearing aids should consider alternatives. At this price point, competitors like the Elehear Beyond and Apple AirPods Pro 2 offer substantially higher overall scores. The Linner Mercury may suit budget-conscious first-time users who prioritize stable, feedback-free wear over streaming capabilities or challenging listening environments. However, those seeking better speech clarity or music quality should explore other options in this price range.
