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

EarCentric EasyCharge
The EarCentric EasyCharge is a budget-priced prescription behind-the-ear hearing aid released in 2023, earning a C grade with a SoundScore of 2.7/5 in our lab testing. At $229, it sits at the entry level of the prescription hearing aid market. In our standardized testing, this device showed a significant performance gap compared to the prescription hearing aid category. Speech clarity scores were notably low, measuring 2.32 points below the category average in quiet environments and 0.96 points below average in noisy settings. Music streaming performance was similarly limited at 0.0/5, falling 2.64 points below average. Own-voice comfort scored 1.9/5, which is 0.85 points below the category norm. The EasyCharge's standout feature is its excellent feedback handling, scoring a perfect 5.0/5—0.29 points above the category average of 4.71. This means users are unlikely to experience whistling or squealing during everyday use. The device also offers convenient rechargeable batteries. Within the same budget price range, the RxEars Rxi achieves significantly stronger overall performance with a 4.09/5 SoundScore. Consumers prioritizing sound quality on a tight budget may find better value elsewhere, though the EasyCharge's feedback stability and rechargeable design could appeal to users with modest amplification needs who value convenience over maximum speech clarity.

Otofonix Groove
The Otofonix Groove is a behind-the-ear prescription hearing aid priced at $795, earning a C grade with a SoundScore of 2.7/5 in our lab testing. This rechargeable BTE device ranks 36th out of 36 tested prescription hearing aids, placing it in the bottom tier of its category. In our testing, the Groove demonstrated one clear strength: excellent feedback handling at 5.0/5, scoring 0.29 points above the category average. The device remained stable during our standardized challenge motions with no audible feedback issues. However, speech performance was significantly limited, with both speech in quiet and speech in noise scoring 1.0/5—falling 2.32 and 0.96 points below their respective category averages. Music streaming quality scored 0.0/5, which is 2.64 points below the prescription category average. Own-voice comfort was also low at 0.4/5 in the tuned configuration, 2.35 points below average, suggesting notable occlusion-related concerns. The normalized Initial Score of 2.7/5 and Tuned Score of 2.6/5 indicate that professional fitting adjustments did not improve overall performance. Given its positioning at the bottom of the prescription hearing aid category and the availability of lower-priced alternatives that scored higher in our testing, the Otofonix Groove may be difficult to recommend for most users seeking balanced sound quality across listening situations.
