Lexie B2 Plus Hero
LexieSoundScore 4.4Grade A

Lexie B2 Plus

The Lexie B2 Plus is a mid-priced OTC hearing aid that earns an A grade with a SoundScore of 4.4/5 in HearAdvisor's lab testing, ranking #7 among 65 OTC devices. Priced at $899, this behind-the-ear rechargeable device has earned back-to-back Expert's Choice Awards in 2023 and 2024. In our testing, the B2 Plus demonstrates strong speech-in-quiet performance at 4.3/5, which is 1.49 points above the OTC category average. Own-voice comfort is excellent at 4.8/5, measuring 2.29 points above average—a notable strength that may appeal to users who find their own voice bothersome with other devices. Speech-in-noise scores 2.1/5, which is above the category average by 0.58 points but remains mixed in absolute terms, reflecting the broader challenge OTC devices face in noisy environments. The device does show a weakness in feedback handling, scoring 2.8/5—which is 1.74 points below the category average of 4.54/5. Users may encounter occasional whistling during activities that bring objects close to the ear. Music streaming performance is mixed at 2.6/5, though still 0.68 points above the OTC average. The Lexie B2 Plus offers both iPhone and Android streaming compatibility. It's well-suited for users prioritizing clear speech in quieter settings and natural own-voice perception, though those frequently in noisy environments or concerned about feedback stability may want to consider alternatives like the Sony CRE-E10 in this price range.

Linner Mars Hero
LinnerSoundScore 3.1Grade B

Linner Mars

The Linner Mars is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.1/5 in our lab testing. At $399, it falls in the lowest price tier for OTC devices, though its overall sound performance ranks #55 of 65 in the OTC Hearing Aid category. This device presents a stark contrast in performance across different listening situations. Music streaming is a genuine standout, scoring an excellent 4.6/5—well above the category average. Feedback handling also earns a perfect 5.0/5, meaning users shouldn't experience whistling or squealing issues. However, the Mars struggles significantly with its core hearing aid function: speech clarity. Speech in quiet scores just 1.9/5, and speech in noise drops to 1.0/5, both falling below category averages. Own-voice comfort is another weak point at 1.0/5, which is 1.51 points below the category average. Users may find their own voice sounds unnatural or boomy when wearing these devices. The tuned fit shows modest improvement over the initial fit (3.4/5 vs 3.1/5), primarily through better speech-in-quiet performance. The Linner Mars may appeal to budget-conscious consumers who prioritize music and media streaming over speech understanding. However, several competitors in the same price range—including the Elehear Beyond and Apple AirPods Pro 2—offer substantially better overall sound performance. Those seeking improved speech clarity should consider alternatives that score higher in that critical area.
