Jabra Enhance Select M3
The Jabra Enhance Select M3 is a premium OTC hearing aid priced at $1,995, earning an A grade with a SoundScore of 4.0/5 in our lab testing. This behind-the-ear device delivers strong overall performance, positioning it among the better-performing options in the OTC category. In our testing, the Enhance Select M3 showed notable strengths in speech clarity during quiet environments, scoring 3.8/5—a solid result that sits 0.95 points above the OTC category average. Music streaming quality also performs well at 2.8/5, which is 0.87 points above average for the category, though still mixed in absolute terms. Feedback handling is excellent at 4.6/5, ensuring stable performance during movement and daily activities. The device does show limitations in challenging listening environments. Speech in noise scored 1.3/5, which falls 0.18 points below the category average and represents a low absolute score. Users who frequently encounter noisy restaurants, busy social gatherings, or similar environments may find this a meaningful limitation. Own-voice comfort scored 2.7/5—above the category average by 0.18 points but only mixed in absolute terms. Consumers seeking strong performance in quieter settings with good music streaming capability may find the Enhance Select M3 appealing. However, shoppers should note that alternatives like the Sennheiser All Day Clear and Jabra Enhance Pro 20 at Costco offer comparable or higher scores at lower price points, potentially representing better overall value for budget-conscious buyers.

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.
