Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

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.

Otofonix Elite
The Otofonix Elite is a behind-the-ear amplification product priced at $249, earning a C grade with a SoundScore of 2.6/5 in HearAdvisor's lab testing. Released in 2016, this budget amplifier ranks #8 of 8 in the Amplification Product category. In our lab testing, the Elite demonstrates one clear strength: excellent feedback handling at 5.0/5, which is 0.72 points above the category average. This means users are unlikely to experience whistling or squealing during normal use. However, the device shows significant limitations in other areas. Speech performance is notably limited, with speech in quiet scoring 1.0/5 (1.11 points below category average) and speech in noise also at 1.0/5 (0.37 points below average). The device does not support Bluetooth streaming, resulting in a 0.0/5 music streaming score. Own-voice comfort is particularly low at 0.1/5, falling 2.54 points below the category average—users may notice their own voice sounds unnatural or boomy. At this price point, consumers may want to consider alternatives that offer better overall performance. Several devices with higher SoundScores are available at lower prices, including the Audien Hearing Atom (3.31/5) and HSKLock Hearing Aid (3.00/5). The Otofonix Elite may appeal to those prioritizing feedback-free operation above all else, but its limited speech clarity and lack of streaming make it difficult to recommend for general use.
