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 Mercury Hero

Linner Mercury

The Linner Mercury is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.1/5 in our lab testing. Priced at $387, it ranks #60 of 65 devices in the OTC Hearing Aid category, placing it in the top 91% of the category. In our testing, the Mercury shows a mixed performance profile. Its standout strength is excellent feedback handling at 4.7/5, which is 0.16 points above the category average—meaning users are unlikely to experience whistling or squealing during normal use. However, speech clarity metrics fall below category norms: speech in quiet scores 2.2/5 (0.62 points below average), and speech in noise scores a low 1.0/5 (0.48 points below average). Own-voice comfort also scores low at 1.6/5, sitting 0.91 points below the category average. Music streaming is a notable weakness, scoring 0.0/5—a full 1.92 points below the category average. Users who prioritize streaming audio from their phone should consider alternatives. The device uses a rechargeable battery and features a visible in-ear design with power dome coupling. At this price point, several competitors offer stronger overall performance. The Linner Mercury may appeal to budget-conscious consumers who prioritize feedback-free operation over speech clarity and streaming quality, but those seeking better speech understanding in challenging environments should explore higher-scoring options in this price range.
