Feedback handling is excellent at 5.0/5, exceeding the already-high category average by 0.46 points. Own-voice comfort scores 2.7/5, slightly above the category average but only mixed in absolute terms. The AuraLink's limitations appear in speech clarity metrics. Speech in quiet scores 2.3/5, falling 0.47 points below the category average—a mixed result that may affect conversational understanding in calm environments.

This hearing aid may appeal most to users who prioritize music listening and phone streaming over speech clarity in challenging environments.
