HearingAssist Micro

The HearingAssist Micro is a premium amplifier in the invisible-in-ear style, priced at $698. In our lab testing, it earned a B grade with a SoundScore of 3.6/5, placing it #3 among the 8 amplification products we've tested. This device shows a clear strength in speech clarity during quiet environments, scoring 3.5/5—a solid result that sits 1.35 points above the category average of 2.11/5. Feedback handling is also strong at 4.0/5, though slightly below the category average of 4.28/5. Own-voice comfort comes in at 2.8/5, which is above the category average but only mixed in absolute terms. The Micro has notable limitations. Speech-in-noise performance is low at 1.1/5, falling 0.31 points below the category average. Music streaming is where this device struggles most significantly, scoring 0.0/5—well below the already modest category average of 1.16/5. Users who want to stream audio from their phone should look elsewhere. The HearingAssist Micro may suit those prioritizing discreet, invisible-in-ear design and clear speech understanding in quieter settings. However, buyers seeking strong noise management or any music streaming capability should consider alternatives. At this price point, the Sennheiser Conversation Clear Plus offers notably higher overall performance, while options like the iHear MatriX deliver similar sound quality at a lower price.

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.
