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 showed notable strengths in comfort-related metrics. Own-voice comfort scored a solid 3.7/5, measuring 1.19 points above the category average—a meaningful advantage for wearers sensitive to the sound of their own voice. Feedback handling was excellent at 5.0/5, well above the 4.54 category average, indicating reliable stability during typical wear. Speech performance presented a mixed picture. Speech in quiet scored a solid 3.1/5, sitting 0.27 points above average. However, speech in noise was a weakness at 1.0/5, falling 0.48 points below the category average—an important consideration if challenging listening environments are a priority. Music streaming scored 2.5/5, which is above the category average by 0.58 points but only mixed in absolute terms. At this price point, several alternatives delivered stronger overall performance in our testing, including the Lucid Tala (4.61/5) and Audicus Omni 2 (4.59/5). The Jabra Enhance Select 300 and Lucid Engage also achieved higher scores at lower prices. The Enhance Select 700 may suit those prioritizing own-voice comfort and feedback stability over speech-in-noise performance, but shoppers should weigh these trade-offs carefully given the premium pricing.

Linner Mercury Hero
LinnerSoundScore 3.0Grade B

Linner Mercury

The Linner Mercury is a budget OTC hearing aid priced at $387, earning a B grade with a SoundScore of 3.0/5 in our lab testing. This visible-in-ear style device ranks #60 of 65 in the OTC Hearing Aid category, positioning it in the lower tier of available options. In our standardized testing, the Mercury demonstrates excellent feedback handling at 4.7/5, scoring 0.16 points above the category average. This means users are unlikely to experience whistling or squealing during typical wear. However, the device shows limitations in other key areas. Speech in quiet scores 2.2/5, falling 0.62 points below the category average, while speech in noise performance is low at 1.0/5, sitting 0.48 points below average. Own-voice comfort is also low at 1.6/5, measuring 0.91 points below the category average. The most significant limitation is music streaming, which scores 0.0/5—a full 1.92 points below the category average. Users who plan to stream phone calls or music through their hearing aids should consider alternatives. At this price point, competitors like the Elehear Beyond and Apple AirPods Pro 2 offer substantially higher overall scores. The Linner Mercury may suit budget-conscious first-time users who prioritize stable, feedback-free wear over streaming capabilities or challenging listening environments. However, those seeking better speech clarity or music quality should explore other options in this price range.
