	Silent control. Instant switch. With a single flick, move your audio wherever it needs to be—Quest 3, K4 Duo, or back again.
Folds down. Stays out of the way. The earphones rotate down with ease, and tuck away just as neatly.
	Shifts with you. The arms tilt vertically to match your natural posture—no pressure, just perfect alignment.
Dialed in to the last detail. A final adjustment brings the earphones exactly where they should be—for fit that disappears.
