OrkaSoundScore 4.0Grade A

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.

SennheiserSoundScore 4.1Grade A

Sennheiser All-Day Clear Slim

The Sennheiser All-Day Clear Slim is a premium OTC behind-the-ear hearing aid priced at $1,499, earning an A grade with a SoundScore of 4.1/5. This places it in the top 23% of OTC hearing aids tested in our lab, ranking #16 among 65 devices in its category. This device excels in areas that reflect Sennheiser's audio heritage. Music streaming quality is a standout strength, scoring 3.8/5—a solid result that's 1.88 points above the OTC category average. Feedback handling is excellent at 5.0/5, meaning users can expect stability without whistling during typical use. Speech in quiet environments also performs well at 3.6/5, sitting 0.85 points above average for the category. However, the All-Day Clear Slim shows limitations in other areas. Speech in noise scores 1.5/5, matching the category average but representing a low absolute score that may challenge users in noisy restaurants or group conversations. Own-voice comfort is below average at 1.9/5, which could affect how natural users sound to themselves during conversation. The All-Day Clear Slim is best suited for consumers who prioritize music streaming and media consumption alongside hearing support, and who spend more time in quieter environments. Those frequently navigating noisy social situations may want to compare against higher-ranked competitors in this price range, such as the Lucid Tala or Audicus Omni 2, which achieve stronger overall scores.
