MDHearing VoltMax vs Otofonix Encore

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.

The Otofonix Encore is a budget-priced prescription hearing aid available for $295, earning a C grade with a SoundScore of 2.7/5 in our lab testing. This behind-the-ear device ranks #37 of 39 in the Prescription Hearing Aid category, placing it in the bottom tier of its class. In our standardized testing, the Encore demonstrates one clear strength: excellent feedback handling at 4.7/5, which means users are unlikely to experience whistling or squealing during normal use. However, the device shows significant limitations in other areas. Speech intelligibility scores are low in both quiet (1.0/5) and noisy environments (1.0/5), falling 2.40 and 1.11 points below category averages respectively. Music streaming performance scored 0.0/5, indicating this device is not suitable for those who want to stream audio content. The Encore uses disposable batteries and comes in a traditional behind-the-ear style. Notably, our tuned fit testing showed a slight decrease in overall performance compared to the initial fit, with the normalized score dropping from 2.8/5 to 2.4/5. Own-voice comfort also declined substantially when moving to a more occluding coupling. At this price point, consumers may want to consider alternatives. The RxEars Rxi offers substantially better performance at a similar budget price point with a score of 4.07/5. The Otofonix Encore may appeal to buyers seeking a very low-cost entry into prescription hearing aids who prioritize feedback stability, but those needing reliable speech clarity or streaming capabilities should explore other options.
