The primary limitation is own-voice comfort, which scores 1.2/5—a low result that falls 1.31 points below the category average. Users sensitive to hearing their own voice may find this more noticeable. The device uses closed domes with a medium-power receiver and achieved identical scores in both initial and tuned fit conditions in our testing. The Beyond Pro supports both iPhone and Android streaming with hands-free functionality. It's best suited for users who prioritize streaming audio quality and speech clarity and are less sensitive to own-voice occlusion effects. Within its price range, it competes with devices like the Sony CRE-E10 and Lexie B2 Plus, though some competitors in this tier score higher overall.

The MDHearing VoltMax is a behind-the-ear OTC hearing aid priced at $699, earning a B grade with a SoundScore of 3.0/5 in our lab testing. This places it in the lower tier of the OTC hearing aid category, ranking 62nd out of 65 devices tested. In our testing, the VoltMax delivered mixed results across key performance areas. Its standout strength is excellent feedback handling, scoring a perfect 5.0/5—above the category average by 0.46 points. This means users can expect stable performance without whistling or squealing during typical daily activities. However, speech clarity proved challenging, with speech-in-quiet scoring 1.9/5 (0.93 points below category average) and speech-in-noise at 1.0/5 (0.48 points below average). Own-voice comfort measured 2.4/5, slightly below the category norm. A significant limitation is music streaming, which scored 0.0/5—nearly 2 points below the category average. Users who prioritize phone streaming for calls or media should consider alternatives. The device features rechargeable batteries, offering convenience over disposable options. At this price point, several competitors deliver substantially stronger overall performance. The VoltMax may appeal to budget-conscious consumers who primarily need basic amplification with reliable feedback control and don't require streaming capabilities. Those seeking better speech clarity or music streaming should explore higher-scoring options in this price range.
