EarCentric EasyCharge vs iBstone AuraLink
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 hearing aid available for $229, earning a C grade with a SoundScore of 2.7/5 in our lab testing. This behind-the-ear rechargeable device ranks #36 of 39 prescription hearing aids tested, placing it in the bottom tier of its category. In our standardized testing, the EasyCharge demonstrates a stark performance divide. Its standout strength is feedback handling, scoring an excellent 5.0/5—slightly above the category average of 4.72. This means users can expect stable performance without whistling during typical daily activities. However, speech clarity metrics tell a different story: speech in quiet scores just 1.0/5, which is 2.40 points below the category average, and speech in noise also scores 1.0/5, falling 1.11 points below average. Music streaming scored 0.0/5, indicating this device is not suitable for audio enjoyment. Own-voice comfort is also limited at 1.9/5, which is 0.80 points below the prescription hearing aid average of 2.70. The device showed no improvement between initial and tuned fitting conditions, with both scoring 2.7/5. At this price point, shoppers should note that alternatives exist with meaningfully better performance. The RxEars Rxi, available in the same price range, scores 4.07/5. The EasyCharge may appeal to those prioritizing feedback-free operation on a tight budget, but its low speech clarity scores suggest significant limitations for everyday conversation.

iBstone AuraLink
The iBstone AuraLink is a mid-priced OTC hearing aid released in 2024, earning a B grade with a SoundScore of 3.6/5 in our lab testing. At $649, it ranks #33 of 65 OTC hearing aids tested, placing it in the top 49% of its category. This behind-the-ear device demonstrates a distinctive performance profile with notable strengths in specific areas. Music streaming stands out as a clear highlight, scoring 3.6/5—a solid result that lands 1.68 points above the OTC category average. Feedback handling is excellent at 5.0/5, exceeding the already-high category average by 0.46 points. Own-voice comfort scores 2.7/5, slightly above the category average but only mixed in absolute terms. The AuraLink's limitations appear in speech clarity metrics. Speech in quiet scores 2.3/5, falling 0.47 points below the category average—a mixed result that may affect conversational understanding in calm environments. Speech in noise presents a more significant challenge at 1.0/5, which is 0.48 points below the category average and low in absolute terms. This hearing aid may appeal most to users who prioritize music listening and phone streaming over speech clarity in challenging environments. However, budget-conscious shoppers should note that alternatives like the iHear MatriX offer higher scores at lower prices. The AuraLink's strength in feedback stability and streaming audio quality represents a specific value proposition for users whose priorities align with these capabilities.
