Jabra Enhance Select 300
The Jabra Enhance Select 300 is a premium OTC hearing aid priced at $1,695 that earns an A grade with a SoundScore of 4.1/5 in our lab testing. This behind-the-ear device ranks #17 out of 65 OTC hearing aids tested, placing it in the top 25% of its category. In our standardized testing, speech clarity in quiet environments stands out as a notable strength, scoring 3.6/5—a solid result that sits 0.85 points above the category average. Feedback handling is excellent at 5.0/5, meaning users should experience stable performance without whistling during typical wear. Own-voice comfort also performs well at 3.5/5, nearly a full point above average, which can contribute to a more natural listening experience. Speech understanding in noisy environments presents a limitation, scoring 1.5/5—essentially at the category average but low in absolute terms. This is a common challenge across OTC devices, though users seeking strong noise performance may want to compare alternatives. Music streaming scores 2.6/5, which is above the category average by 0.68 points but mixed in absolute quality. The Enhance Select 300 offers rechargeable batteries and streaming compatibility with both iPhone and Android devices, along with hands-free functionality. It has earned Expert's Choice Awards in both 2023 and 2024. Shoppers in this price range should note that alternatives like the Lucid Tala and Audicus Omni 2 score higher overall, while options like the Jabra Enhance Pro 20 at Costco offer similar sound quality at a lower price point. This device is best suited for those prioritizing speech clarity in quieter settings and stable, feedback-free performance.

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.
