Fitting
ISOtunes
®
PRO comes with 4 sets of TRILOGY
™
Foam eartips (XS,S,M,L) and 1 set of
rubber triple fl ange eartips. The foam eartips have been specifi cally designed for use
with
ISOtunes
®
PRO and are made from a heat-activated memory foam which allows
long term, comfortable wear and enhanced sound performance. The foam eartips
provide maximum noise reduction while the rubber eartips are recommended for use
in less noisy situations.
The device comes with the Medium size eartips already in place. Choose the eartip size
that fi ts most snugly in your ear canal. Remember, the snugger the fi t, the better the
noise attenuation.
PLEASE NOTE: The core of the foam eartips are threaded, as are
the posts on the earphones that they attach to. Please
GENTLY twist foam on/off to
replace the eartips.
Place the wire around the back of your
neck in preparation for inserting the
eartips. Grasp the right earbud with your
right hand. With your left hand, compress
the foam for easier insertion. Once the
foam is suffi ciently compressed, release
the foam and use your left hand to pull
your right ear back and away from your
head to open your ear canal, as shown
in the illustration below. With your right
hand, insert the earbud into your ear
canal, working it is as deeply as you are
comfortable with for maximum noise
attenuation. Repeat for the opposite side.
Once the earbuds have been placed, the
foam tips will expand to fi ll your ear canal,
