HOW TO CHANGE WINGS
1. Grip the CORE with one hand and the heel of the WING with the other.
2. Note that core and wings for the left ear are marked with a L and core and wings for the right ear are marked with a R, if the letters on both the core and the wing are aligned you are doing it right.
3. Insert the rib of the CORE into the groove of the WING. Hold the CORE between your thumb and index finger. Secure the WING by pinching it between your thumb and the CORE. While pinching one side of the WING, stretch it gently while mounting it onto the rib of the CORE with a circular motion.
4. With the rotation guide snapped in place, gently pull the remaining part of the WING over the rib of the CORE until it snaps in position.
