Orka Two
The Orka Two is a behind-the-ear prescription hearing aid priced at $1,899, earning an A grade with a SoundScore of 4.0/5 in our lab testing. This places it in the top 67% of the 36 prescription hearing aids we've evaluated, ranking #25 in its category. In our testing, the Orka Two shows a mixed performance profile with clear strengths and weaknesses. Music streaming stands out at 3.3/5, measuring 0.66 points above the category average—a solid result for users who prioritize phone audio quality. Own-voice comfort also performs well at 3.2/5, sitting 0.45 points above average, which may contribute to a more natural listening experience. Feedback handling is excellent at 5.0/5, among the best we've measured. However, speech-in-noise performance is a notable limitation. At 1.4/5, it falls 0.56 points below the category average—a low absolute score that may affect understanding in challenging listening environments like restaurants or group conversations. Speech in quiet fares better at 3.7/5, measuring 0.40 points above average. The Orka Two may suit users who prioritize streaming quality, own-voice comfort, and stability over speech-in-noise performance. Those frequently in noisy environments should note that competitors in this price range, such as the Rexton Reach R-Li T80 at Costco (4.58/5), deliver stronger overall scores. Budget-conscious shoppers might also consider lower-priced alternatives like the Sony CRE-C10, which scored 4.19/5 in our testing.
