Rexton Reach R-Li T80 at Costco
The Rexton Reach R-Li T80, available exclusively at Costco for $1,500, is a behind-the-ear prescription hearing aid that earned an A grade and ranks #11 of 36 devices in its category in our lab testing. This 2024 release earned HearAdvisor's Expert's Choice Award, reflecting its strong overall performance. In our standardized testing, the Reach R-Li T80 delivered a SoundScore of 4.6/5, placing it in the top 28% of prescription hearing aids. Speech clarity stands out as a particular strength, scoring 3.9/5 in quiet environments—0.54 points above the category average. Own-voice comfort also impressed at 3.6/5, a full 0.85 points above average, suggesting wearers may experience less of the "talking in a barrel" sensation that can occur with hearing aids. Feedback handling is excellent at 4.8/5. Speech-in-noise performance scores 2.5/5, which is above the category average by 0.54 points but remains mixed in absolute terms—a common challenge across prescription devices. Music streaming similarly scores 2.7/5, slightly above average but not a standout feature. This device supports both iPhone and Android streaming, offers hands-free functionality, and uses rechargeable batteries. For Costco members seeking a prescription hearing aid with reliable speech clarity, strong own-voice comfort, and excellent feedback control at a mid-tier price point, the Reach R-Li T80 represents solid value in our testing framework.

Sennheiser All-Day Clear Slim
The Sennheiser All-Day Clear Slim is a premium behind-the-ear OTC hearing aid priced at $1,499, earning an A grade with a SoundScore of 4.1/5 in our lab testing. This places it in the top 23% of the OTC hearing aid category, ranking #16 among 65 tested devices. In our testing, the All-Day Clear Slim demonstrates notable strengths in music streaming, scoring 3.8/5—a solid result that sits 1.88 points above the category average. This makes it one of the stronger performers for users who prioritize audio quality when streaming from their phone. Feedback handling is excellent at 5.0/5, measuring 0.46 points above the category average, meaning users can expect stable performance without whistling during typical daily activities. Speech clarity in quiet environments is solid at 3.6/5, coming in 0.85 points above the category average. However, speech in noise performance is low at 1.5/5, matching the category average—a common limitation across OTC devices. Own-voice comfort scores 1.9/5, which is 0.61 points below the category average, suggesting some users may notice their own voice sounds different or hollow. The All-Day Clear Slim includes rechargeable batteries and supports streaming to both iPhone and Android devices with hands-free functionality. At its price point, alternatives like the Lucid Tala and Audicus Omni 2 offer higher overall scores, though the Sennheiser may appeal to those who value the brand's audio heritage and prioritize music streaming quality over speech-in-noise performance.
