EarCentric EX2 vs HearingAssist Micro
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

EarCentric EX2
The EarCentric EX2 is a budget-priced prescription behind-the-ear hearing aid released in 2021, earning a C grade with a SoundScore of 2.7/5 in HearAdvisor's lab testing. At $218, it ranks #33 of 36 prescription hearing aids tested, placing it in the bottom 11% of its category. In our testing, the EX2 showed a significant split in performance. Feedback handling was excellent at 4.7/5, essentially matching the category average and demonstrating stable operation during movement. However, speech performance was notably limited, with both speech in quiet and speech in noise scoring 1.0/5—well below the category averages of 3.32 and 1.96 respectively. Music streaming scored 0.0/5, falling 2.64 points below the prescription category average of 2.64/5. Own-voice comfort scored 2.3/5, a mixed result that sits 0.45 points below the category average. The device uses a rechargeable battery, which adds convenience for daily use. Notably, tuning did not improve performance in our testing—the Initial and Tuned fit scores were identical at 2.7/5. Budget-conscious shoppers in this price range may want to compare alternatives. The RxEars Rxi scored 4.09/5 at a similar price point, while OTC options like the Audien Hearing Atom offer comparable or better sound performance at lower prices. The EX2 may suit users who prioritize feedback stability and rechargeable convenience over speech clarity, but its limited speech performance is a significant tradeoff.

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.
