HearingAssist Micro vs Otofonix Encore
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 Encore
The Otofonix Encore is a behind-the-ear prescription hearing aid priced at $295, placing it in the budget tier of the prescription category. In our lab testing, it earned a C grade with a SoundScore of 2.7/5, ranking 35th out of 36 prescription hearing aids tested. Sound performance presents significant challenges across most metrics. Speech clarity scores are low in both quiet (1.0/5) and noisy environments (1.0/5), falling 2.32 and 0.96 points below category averages respectively. Music streaming capability is essentially absent at 0.0/5, and own-voice comfort is notably limited at 0.1/5 in the tuned configuration—2.65 points below the category average. The one bright spot is feedback handling, which scores an excellent 4.7/5. While this falls just 0.01 points below the category average, it represents strong absolute performance that should minimize whistling issues during daily use. This device runs on disposable batteries. At this price point, shoppers should be aware that the RxEars Rxi offers substantially better sound performance (4.09/5) in the same price range. The Otofonix Encore may suit budget-conscious consumers who prioritize feedback stability over speech clarity and streaming features, but our testing suggests most users would benefit from considering higher-performing alternatives within this price tier.
