Quality data starts with quality recordings. HearAdvisor worked with GRAS to build a no-compromise front end so every test is repeatable and reliable.

The RCA In-Ear is a budget-priced OTC hearing aid with excellent feedback handling but significantly limited speech clarity performance.
- Excellent feedback handling5.0/5
- Budget-friendly entry price point
- Natural own voice quality2.6/5
- Very poor speech in quiet-0.5/5
- Below-average speech in noise-0.8/5
- No music streaming capability0.0/5
In initial fit testing with closed vented domes, the RCA In-Ear scored 1.7/5. Speech understanding metrics were low, with speech in quiet at -0.5/5 and speech in noise at -0.8/5—both well below category averages. Feedback handling was excellent at 5.0/5, and own-voice comfort was mixed at 2.6/5. Music streaming scored 0.0/5, indicating no meaningful audio fidelity for streamed content. These results suggest limited benefit for speech clarity out of the box.
