Uses Official HearAdvisor Lab Data
GoHearing Ultra Hero
GoHearingSoundScore 3.1Grade B

GoHearing Ultra

The GoHearing Ultra is a budget-priced behind-the-ear OTC hearing aid that earns a B grade with a SoundScore of 3.1/5 in our lab testing. At $499, it sits in the most affordable price tier of the OTC market, though its overall sound performance ranks #58 of 65 devices in its category. In our testing, the Ultra shows a distinctive performance profile with significant strengths and weaknesses. Feedback handling is excellent at 5.0/5, scoring 0.46 points above the category average—users can expect stable operation without whistling during typical wear. Music streaming quality is also a genuine strength at 3.6/5, performing 1.68 points above average, making it notably better for phone audio than most OTC devices. However, speech clarity scores reveal meaningful limitations. Speech in quiet environments measured just 1.0/5, which is 1.79 points below the category average and low in absolute terms. Speech in noise similarly scored 1.0/5, falling 0.48 points below average. Own-voice comfort rated 1.9/5, also below the category norm. These results suggest the Ultra may struggle to deliver the speech audibility improvements that many users prioritize. The GoHearing Ultra may suit budget-conscious consumers who primarily want reliable streaming audio and feedback-free operation, and who have modest expectations for speech enhancement. However, several competitors in the same price range—including the Elehear Beyond and Apple AirPods Pro 2—deliver substantially stronger overall sound performance. Users prioritizing speech clarity should consider these alternatives despite similar pricing.

MDHearing VoltMax Hero
MDSoundScore 3.0Grade B

MDHearing VoltMax

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.
