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.
