Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Jabra Enhance Select 700
The Jabra Enhance Select 700 is a premium-priced OTC hearing aid available at $1,795, earning a B grade with a SoundScore of 3.8/5 in our lab testing. This behind-the-ear device ranks #26 of 65 OTC hearing aids tested, placing it in the top 38% of the category. In our testing, the Enhance Select 700 shows notable strengths in own-voice comfort, scoring 3.7/5—a solid result that sits 1.19 points above the category average. This makes it a comfortable choice for users sensitive to the "hollow" sound of their own voice that some hearing aids produce. Feedback handling is excellent at 5.0/5, meaning users can expect stable performance without whistling during typical daily activities. Speech clarity in quiet environments is solid at 3.1/5, coming in 0.27 points above the category average. However, speech understanding in noisy settings is a weakness, scoring just 1.0/5—falling 0.48 points below the category average. Users who frequently encounter restaurants, group gatherings, or other challenging listening environments may find this limitation significant. Music streaming quality is mixed at 2.5/5, though still 0.58 points above the category average. At this price point, buyers should note that several same-priced alternatives deliver stronger overall performance, including the Lucid Tala (4.63/5) and Audicus Omni 2 (4.61/5). The Enhance Select 700 is best suited for users who prioritize own-voice comfort and feedback-free wear over speech-in-noise performance, and who value Jabra's established brand and support ecosystem.

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.
