The planar tweeter sits a hair behind the dynamic driver, so highs arrive a moment cleaner — cymbals with air around them, voices set forward and dry.
Hybrid adaptive cancellation reads the room two hundred times a second and folds the world down to a hush, leaving only what you chose to hear.
The Feel The case closes with a single magnetic note — a small, deliberate sound you learn to expect. Titanium warms to the hand; the seam catches the light only when you turn it. Nothing here asks for attention, which is rather the point.
It is the rare object that feels finished — not styled, not loud, just resolved down to the last gram and left exactly there. From the field notes · Sona Atelier
