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 iBstone AuraLink delivers excellent feedback handling and strong music streaming, but struggles significantly with speech clarity in noisy environments.
- Perfect feedback handling5.0/5
- Strong music streaming+1.73 above category
- Above-average own voice quality
- Very poor speech in noise-0.1/5
- Below-average speech in quiet2.2/5
In initial fit testing with tulip dome coupling, the AuraLink achieved a normalized score of 3.2/5. Speech in quiet measured 2.2/5, below the category average, while speech in noise was notably low at -0.1/5. The device excelled in feedback handling with a perfect 5.0/5 and delivered solid music streaming at 3.6/5. Own-voice comfort was mixed at 2.7/5, slightly above the OTC average. The initial fit reflects the manufacturer's proprietary default settings.
