Jabra Enhance Select 300 Hero
JabraSoundScore 4.1Grade A

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 among 65 OTC hearing aids tested, placing it in the top 25% of its category. In our testing, the Enhance Select 300 demonstrates notable strengths in speech clarity for quiet environments, scoring 0.85 points above the OTC category average. Feedback handling is excellent at 5.0/5, and own-voice comfort scores a solid 3.5/5—nearly a full point above average for the category. Music streaming performance, while above average for OTC devices, remains mixed in absolute terms at 2.6/5. The device's main limitation appears in challenging listening environments. Speech-in-noise performance scored 1.5/5, which is low in absolute terms and essentially matches the category average. Users who frequently encounter noisy restaurants, busy offices, or crowded gatherings may find this a meaningful constraint. The Enhance Select 300 is best suited for individuals who primarily need improved hearing in quieter settings such as home conversations, one-on-one meetings, or watching television. It offers reliable streaming to both iPhone and Android devices, rechargeable batteries, and hands-free functionality. Shoppers seeking stronger noise performance at this price point may want to compare alternatives like the Lucid Tala or Audicus Omni 2, which scored higher overall in our testing.

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.
