Jabra Enhance Pro 20 at Costco
The Jabra Enhance Pro 20 at Costco is a behind-the-ear prescription hearing aid priced at $1,600, placing it in the premium tier. With a SoundScore of 4.0/5 and an A grade, it ranks #25 of 39 prescription hearing aids tested in our lab. In our testing, this device demonstrates notable strengths in own-voice comfort, scoring 3.5/5—0.80 points above the category average. This solid performance means wearers may find their own voice sounds more natural compared to many competitors. Feedback handling is excellent at 4.8/5, slightly above the category average, indicating reliable stability during movement and phone use. However, the Enhance Pro 20 shows limitations in challenging listening environments. Speech-in-noise performance scores just 1.1/5, falling 0.97 points below the category average—a significant gap that may affect conversations in restaurants, social gatherings, or other noisy settings. Speech-in-quiet is solid at 3.2/5 in absolute terms, though still 0.17 points below the category average. Music streaming scores 2.8/5, which is above the category average but only mixed in absolute terms. This device suits users who prioritize comfortable own-voice perception and excellent feedback control, and who spend most listening time in quieter environments. Those frequently navigating noisy situations may want to consider alternatives like the Rexton Reach R-Li T80 at Costco, which scored 4.56/5 in our testing. The Enhance Pro 20 includes rechargeable batteries, iPhone and Android streaming, and hands-free functionality.

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.
