Jabra Enhance Pro 20 at Costco
The Jabra Enhance Pro 20 at Costco is a prescription behind-the-ear hearing aid available for $1,600, earning an A grade with a SoundScore of 4.0/5 in our lab testing. This places it in the top 61% of the 36 prescription hearing aids we've evaluated. In our testing, this device shows a mixed performance profile. Own-voice comfort is a clear strength, scoring 3.5/5—0.75 points above the category average—making it a solid choice for users who prioritize natural sound quality when speaking. Feedback handling is excellent at 4.8/5, slightly above the category average, indicating stable performance during typical daily activities. However, speech-in-noise performance is notably limited, scoring just 1.1/5—0.82 points below the category average of 1.96. This is a meaningful weakness for users who frequently encounter noisy environments like restaurants or social gatherings. Speech in quiet is solid at 3.2/5, though slightly below the category average. Music streaming scores 2.8/5, above average but only mixed in absolute terms. At this price point, buyers should consider alternatives. The Rexton Reach R-Li T80 at Costco scores 4.58/5 in the same price range, while lower-priced options like the Lexie B3 (4.76/5) offer stronger overall performance. The Jabra Enhance Pro 20 may suit users who prioritize own-voice comfort and feedback stability over challenging listening environments, but those needing robust noise handling should explore other options.

Linner Mars
The Linner Mars is a budget-priced OTC hearing aid released in 2023, earning a B grade with a SoundScore of 3.2/5 in our lab testing. At $399, it falls in the lower price tier of the OTC category but ranks #55 of 65 OTC devices tested, placing it in the bottom 17% of its category. This visible-in-ear device presents a mixed performance profile with notable strengths and significant weaknesses. Music streaming is a standout feature, scoring an excellent 4.6/5—a full 2.68 points above the category average. Feedback handling is also excellent at 5.0/5, meaning users can expect stable performance without whistling during normal use. However, speech clarity presents challenges. Speech in quiet scores a low 1.9/5, falling 0.85 points below the category average. Speech in noise performance is particularly limited at 1.0/5, sitting 0.46 points below average. Own-voice comfort also scores low at 1.0/5, which is 1.51 points below the category average—users may notice their own voice sounding unnatural or boomy. The Linner Mars may suit budget-conscious consumers who prioritize music and media streaming over speech understanding in challenging environments. However, buyers seeking better speech performance should consider alternatives like the Elehear Beyond or Apple AirPods Pro 2, which offer stronger overall sound scores in the same price range.
