2. Fitting your C5 Series 2 in-ear
headphones
Fitting your in-ear headphones correctly will
help ensure that their performance reaches its
full potential. First, identify the left and right
headphones. Identication legends are engraved
on the body of each one. This is illustrated in
Diagram 1.
2.1 Selecting headphone tips
The performance of your C5 Series 2 headphones
will only be realised by using the ear tips that most
closely match the size of your ear canals. The
headphones are supplied with extra small, small
(pre-tted), medium and large ear tips. Ear tips
are removed by gently pulling them away from the
headphone body and tted simply by pushing them
in to place. Experiment with the ear tips to nd the
tightest seal in your ear canals. Diagram 2 illustrates
removal and tting of ear tips.
2.2 Adjusting the cable loops
Headphone t can be adjusted by lengthening
or shortening the Secure Loop so that it presses
against the inner part of the ear to help retain the
headphone in place. This is illustrated in Diagram 3.
2.3 Removing the cable loops
If desired, your C5 Series 2 headphones can be
used without the Secure Loop. To remove the loops,
slide the stopper down the cable, opening up the
end of the sleeve. Then pass the cable through the
circular slot on the side of the headphone until the
thinner section of cable enables its release. Reverse
this procedure to re-establish the loops. Diagram
4 illustrates removal and re-establishment of the
Secure Loop design cable loops.
