Replacing the arc supporters
M-sized arc supporters come attached to the left and right units of the headset at the time of purchase.
If you feel the size of the arc supporters does not fit to your ears, change the arc supporters to another size to
comfortably and snugly fit your left and right ears.
Remove the earbud, then remove the arc supporter.
