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. It ranks #27 of 39 devices in the Prescription Hearing Aid category, placing it in the top 67% of its class. In our testing, the Orka Two demonstrates notable strengths in several areas. Speech in quiet environments scores a solid 3.7/5, measuring 0.32 points above the category average. Music streaming quality also performs well at 3.3/5, sitting 0.54 points above average—a plus for users who frequently stream audio from their phones. Own-voice comfort scores 3.2/5, which is 0.50 points above the category norm, and feedback handling is excellent at a perfect 5.0/5. The device's most significant limitation is speech understanding in noisy environments, where it scores 1.4/5—a low result that falls 0.71 points below the category average. This weakness may impact users who frequently encounter challenging listening situations like busy restaurants or social gatherings. The Orka Two includes Bluetooth streaming for both iPhone and Android devices, hands-free calling capability, and rechargeable batteries. While it delivers solid overall performance for its price tier, shoppers comparing options in this range should note that some competitors like the Rexton Reach R-Li T80 at Costco achieve higher overall scores. The Orka Two is best suited for users who prioritize quiet conversation clarity, streaming quality, and comfort, and who encounter noisy environments less frequently.

Sontro Soundwave
The Sontro Soundwave is a mid-priced OTC hearing aid that earns a B grade with a SoundScore of 3.0/5 in our lab testing. At $849, this behind-the-ear device uses disposable batteries and sits in the lower tier of OTC performance, ranking #61 of 65 devices in its category. The Soundwave's strongest attribute is own-voice comfort, scoring 3.6/5—a solid result that sits 1.09 points above the OTC category average. This makes it relatively comfortable for wearers who are sensitive to hearing their own voice sound unnatural or boomy. However, other performance areas present significant limitations. Speech clarity scores are below average in both quiet and noisy environments. Speech in quiet scores 2.7/5 (0.12 points below average), while speech in noise drops to 1.2/5 (0.28 points below average). Feedback handling is a notable weakness at 2.5/5, falling 2.04 points below the category average of 4.54/5. Perhaps most limiting is the music streaming score of 0.0/5, indicating this device does not support phone audio streaming—a feature many competitors in this price range offer. Consumers prioritizing own-voice comfort on a moderate budget may find the Soundwave acceptable, but those seeking strong speech clarity or streaming capability should consider alternatives. Several higher-performing OTC devices are available at similar or lower price points, including options like the Lexie Lumen or HearingAssist Control that deliver comparable or better overall sound quality.
