The HearingAssist Control is a mid-priced OTC behind-the-ear hearing aid available at $549. In our lab testing, it earned a B grade with a SoundScore of 3.3/5, placing it in the top 77% of OTC hearing aids tested. This device demonstrates solid speech performance, scoring above the category average in both quiet and noisy environments. Speech in quiet earned a solid 3.4/5, while speech in noise scored 2.0/5—above average for the category but only mixed in absolute terms. Feedback handling is excellent at 5.0/5, meaning wearers should experience minimal whistling during normal use. The HearingAssist Control has notable limitations. Music streaming scored 0.0/5, indicating this device does not support audio streaming functionality—a significant gap compared to many competitors in this price range. Own-voice comfort scored 2.1/5, which is below the category average and may result in a hollow or boomy perception of your own voice. For shoppers considering this price tier, alternatives like the Yeasound RIC800 (4.73/5) and Sony CRE-E10 (4.66/5) offer substantially higher overall sound performance. The HearingAssist Control may suit buyers prioritizing speech clarity and feedback stability who don't need streaming capabilities, but most users would benefit from exploring higher-scoring options at similar price points.

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.
