EarCentric EX2 vs Linner Nova Earbud
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.

Linner Nova Earbud
The Linner Nova Earbud is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.5/5 in our lab testing. Priced at $299, this visible-in-ear device offers an interesting performance profile that sets it apart from typical hearing aids in its category. The Nova Earbud's standout strength is its excellent music streaming quality, scoring 4.5/5—a full 2.58 points above the OTC category average. This makes it one of the better options for users who prioritize audio entertainment through their hearing devices. Feedback handling is equally impressive at 5.0/5, meaning users can expect stable performance without the whistling that plagues some competitors. However, the device shows significant limitations in core hearing aid functions. Speech in quiet environments scores a mixed 2.1/5, falling 0.71 points below the category average. Speech in noise performance is low at 1.3/5, slightly below average for the category. Own-voice comfort is notably weak at 0.5/5, sitting 2.01 points below the category average—users may find their own voice sounds unnatural or boomy. The Linner Nova Earbud is best suited for budget-conscious consumers who value music streaming and stable feedback performance over maximum speech clarity. Those prioritizing speech understanding, particularly in noisy environments, may want to consider alternatives like the higher-scoring Elehear Beyond or Apple AirPods Pro 2 in the same price range.
