iBstone AuraLink

The iBstone AuraLink is a mid-priced OTC hearing aid released in 2024, earning a B grade with a SoundScore of 3.6/5 in HearAdvisor's lab testing. This behind-the-ear device ranks #33 among 65 tested OTC hearing aids, placing it in the top 49% of its category. In our testing, the AuraLink shows a distinctive performance profile with notable strengths in audio entertainment. Music streaming scored a solid 3.6/5, measuring 1.68 points above the category average—a standout result for an OTC device. Feedback handling earned an excellent 5.0/5, sitting 0.46 points above average, meaning users should experience minimal whistling during daily wear. However, speech clarity presents a different picture. Speech in quiet scored a mixed 2.3/5, falling 0.47 points below the category average of 2.79. Speech in noise performance was low at 1.0/5, trailing the already modest category average by 0.48 points. Own-voice comfort scored 2.7/5, slightly above average but only mixed in absolute terms. At $649, the AuraLink faces competition from alternatives offering similar or better sound performance at lower prices, including the iHear MatriX and Olive Union Max. The AuraLink may appeal to users who prioritize music and media streaming over speech enhancement, but those seeking stronger speech clarity should explore other options in this price range.

Lucid Ultra 128

The Lucid Ultra 128 is a premium behind-the-ear prescription hearing aid priced at $5,000, earning an A grade with a SoundScore of 4.4/5 in our lab testing. It ranks #16 of 36 devices in the Prescription Hearing Aid category. Speech performance is a clear strength for the Ultra 128. In our testing, speech in quiet scored a strong 4.3/5, landing 1.03 points above the category average. Speech in noise measured 2.7/5—above the category average by 0.74 points, though mixed in absolute terms. These results suggest the device prioritizes intelligibility in everyday listening situations. The Ultra 128 does show notable weaknesses. Feedback handling scored just 1.7/5, falling 3.01 points below the category average of 4.71/5—a significant gap that prospective buyers should consider. Music streaming measured 2.3/5, slightly below the category average. Own-voice comfort was mixed at 2.9/5, though this sits just above the category norm. The device uses disposable batteries and supports streaming to both iPhone and Android. At this price point, buyers may want to compare against higher-scoring competitors like the Phonak Sphere Infinio (5.0/5) or Oticon Intent (4.85/5). The Lucid Ultra 128 may suit those who prioritize speech clarity in quieter environments and can work with their hearing care provider to manage its feedback limitations.
