to the exploded view and proceed as follows:
(a) To change eartips, detach the eartip from the
elbow. Position the replacement eartip over the

elbow and press firmly on the eartube to secure.
(c) To replace an acoustic tube, gently pry the
acoustic tube adapter away from the earphone by
sliding a thin object between the adapter and the
