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

HearingAssist Control
The HearingAssist Control is a behind-the-ear OTC hearing aid priced at $549, earning a B grade with a SoundScore of 3.3/5 in our lab testing. This places it in the lower portion of the OTC category, ranking #51 of 65 devices tested. In our testing, the Control demonstrates notable strengths in speech performance. Speech in quiet scores 0.59 points above the category average at 3.4/5, representing solid absolute performance. Speech in noise comes in at 2.0/5—above the category average by 0.56 points, though only mixed in absolute terms. Feedback handling is excellent at 5.0/5, meaning the device remained stable without audible squealing during our standardized challenge tests. The device shows significant weaknesses in other areas. Music streaming scored 0.0/5, which is 1.92 points below the category average and indicates this device does not support or perform well with phone audio streaming. Own-voice comfort is also below average at 2.1/5 (0.41 points below category average), which may be noticeable during extended conversations. The HearingAssist Control may suit users who prioritize speech clarity over streaming functionality and who don't require premium sound quality across all use cases. However, buyers in this price range should note that several competitors—including the Yeasound RIC800 and Sony CRE-E10—deliver substantially higher overall scores. Those seeking similar speech performance at a lower cost may also consider the iHear MatriX.

iHear MatriX
The iHear MatriX is a behind-the-ear OTC hearing aid priced at $499, earning a B grade with a SoundScore of 3.8/5 in our lab testing. This places it in the top 40% of OTC hearing aids, offering solid performance at a budget-friendly price point. In our testing, the MatriX demonstrated notable strengths in speech intelligibility. Speech in quiet scored a solid 4.0/5, measuring 1.17 points above the category average. Speech in noise performance came in at 2.4/5—above the category average by 0.96 points, though only mixed in absolute terms. Feedback handling was excellent at 5.0/5, surpassing the already-strong category average by 0.46 points, meaning users can expect reliable stability without whistling during typical wear. The most significant limitation is music streaming, which scored 0.0/5—a full 1.92 points below the category average. Users who prioritize streaming audio from their phone should consider alternatives. Own-voice comfort measured 2.7/5, slightly above category average but still mixed in absolute terms. The MatriX features rechargeable batteries and supports streaming from both iPhone and Android devices. With a normalized Initial Score of 3.7/5 improving to 4.3/5 after tuning, this hearing aid responds well to optimization. It's best suited for users who prioritize speech clarity and feedback-free wear over music streaming quality, and who want a budget OTC option that delivers above-average speech performance in our lab framework.
