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.

Phonak Audéo EON Sphere

The Phonak Audéo EON Sphere is a premium behind-the-ear prescription hearing aid priced at $4,398. In HearAdvisor's lab testing, it earned a SoundScore of 5.0/5 and an A grade, placing it among the top performers in the prescription hearing aid category. Speech performance stands out as this device's greatest strength. Speech in noise scored an excellent 4.5/5, a full 2.53 points above the category average of 1.96/5—a substantial margin that makes this one of the strongest performers in challenging listening environments. Speech in quiet also performed well at 4.3/5, nearly a full point above the category average. These results suggest the Audéo EON Sphere may be particularly well-suited for users who frequently encounter noisy social settings or group conversations. Music streaming delivered a solid 3.7/5, more than a point above the category average of 2.64/5, indicating above-average audio fidelity for phone-streamed content. Own-voice comfort scored 2.8/5, which sits just above the category average but reflects mixed absolute performance—users sensitive to occlusion effects should discuss this with their hearing care provider. Feedback handling scored an excellent 4.6/5 in absolute terms, though it lands slightly below the category average of 4.71/5. The Audéo EON Sphere represents Phonak's latest premium technology and delivers strong results across most metrics in our standardized testing. It's best suited for users prioritizing speech clarity in difficult listening situations who are prepared for the premium price point.
