EarCentric EX2 vs Linner Nova Deluxe
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 Deluxe
The Linner Nova Deluxe is a budget-priced OTC hearing aid available for $299, earning a B grade with a SoundScore of 3.3/5 in HearAdvisor's lab testing. This visible-in-ear style device ranks #53 of 65 OTC hearing aids tested, placing it in the lower tier of its category. In our testing, the Nova Deluxe showed a notable strength in feedback handling, scoring an excellent 5.0/5—0.46 points above the category average. This suggests stable performance without whistling during typical wear. Speech clarity in quiet environments scored a mixed 2.8/5, right at the category average, providing basic conversational support. However, speech understanding in noisy situations scored a low 1.4/5, slightly below average. The device has significant limitations in two areas. Own-voice comfort scored just 0.5/5, which is 2.01 points below the category average, indicating noticeable occlusion effects when speaking. Music streaming scored 0.0/5 in our lab measurements, 1.92 points below average, making this device poorly suited for audio entertainment despite offering iPhone, Android, and hands-free streaming connectivity. At its $299 price point, the Nova Deluxe competes against higher-performing alternatives in the same budget range. This device may suit buyers prioritizing stability and basic speech clarity in quieter settings, but those who stream music or are sensitive to how their own voice sounds should consider other options in this price tier.
