EarCentric EX2

The EarCentric EX2 is a behind-the-ear prescription hearing aid priced at $218, positioning it as a budget-friendly option in the prescription category. In HearAdvisor's lab testing, it earned a C grade with a SoundScore of 2.7/5, ranking #35 of 39 prescription hearing aids tested. This 2021 release demonstrates mixed performance across key metrics. Its standout strength is feedback handling, scoring an excellent 4.7/5—essentially matching the category average and indicating reliable stability during movement. However, speech performance is a significant weakness: speech in quiet scores just 1.0/5 (2.40 points below the category average of 3.40), and speech in noise scores 1.0/5 (1.11 points below average). These low absolute scores suggest limited audibility enhancement in our standardized test conditions. Own-voice comfort scores 2.3/5, which is mixed in absolute terms and 0.40 points below the category average. Music streaming scored 0.0/5, indicating this device is not suited for audio entertainment purposes. The EarCentric EX2 may appeal to budget-conscious consumers who prioritize cost over performance, but alternatives exist at similar or lower price points with stronger test results. The RxEars Rxi, available in the same price range, scored 4.07/5 in our testing. Consumers seeking entry-level amplification should weigh the significant speech clarity limitations against the low purchase price.

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.
