Elehear Beyond
The Elehear Beyond is a budget-priced OTC hearing aid that delivers A-grade performance in our lab testing, ranking #8 among 65 OTC hearing aids tested. At $431, this 2024 behind-the-ear device earned our Expert's Choice Award and represents strong value in the entry-level price tier. In our testing, the Beyond demonstrated particular strength in speech clarity in quiet environments, scoring 4.3/5—a strong result that sits 1.48 points above the OTC category average. Music streaming quality also impressed at 3.8/5, exceeding the category average by 1.88 points. Speech understanding in noisy settings scored 2.3/5, which is above the category average of 1.48/5 but remains mixed in absolute terms—a common challenge across OTC devices. Feedback handling proved excellent at 4.5/5, essentially matching the category average. Own-voice comfort scored 2.6/5, slightly above the OTC average but mixed overall—users sensitive to their own voice may notice some occlusion effects. The device uses a rechargeable battery and supports streaming to both iPhone and Android devices with hands-free functionality. The Elehear Beyond is well-suited for budget-conscious consumers seeking reliable speech clarity in quieter listening situations and quality audio streaming. Those who frequently encounter challenging noise environments may find the speech-in-noise performance adequate but not exceptional. Within its price range, the Beyond outperforms competitors including the Apple AirPods Pro 2 and Zepp Clarity Omni on overall sound quality.

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.
