The
eartip
that
is
most
comfortable
and seals
the
ear
is
the
best
choice.
To properly insert:

up
and
out.
Using a
twisting
motion,
position
the
device
horizontally
in
the
ear
with
the
switch
toward
the
back
of
the
ear.
Note: Eartips are reusable.
Replace
3-flange
eartips
every
60-90
days
and
foam
eartips
regularly.

Feedback
(whistling)
may
be
heard
while inserting
the
device
until it
is
fully
sealed
in
the
ear.

will
go
away
when
the
eartip
is
sealed
in

Deeply

sealed
eartips
reduce
the

sound
in

happens,
try
to
achieve

deeper
seal.

changing
eartips, make sure
the
eartip
fits
securely on
the
stem
