Inserting the Earpiece
Ensuring a Good Acoustical Seal
Your ear tips (also called plugs) are meant to be worn fully inserted into your ear. Ear tips need to form a seal
with all the walls of your ear canal — like a cork in a wine bottle. Proper insertion is key: forming a tight seal
will enhance the performance of your SonX device.
Getting the perfect seal requires nding the correct tip size. Your device comes with assorted sizes of tips as
seen in Selecting a Size and Attaching the Tips. You started with the Standard-sized Comply™ tips. If Standard
size doesn’t give you an adequate seal, move down one size to the smaller tips. Try the largest size last —
you’d be surprised, but a smaller tip sometimes gives you the more comfortable seal. Ears are as unique as
ngerprints. In some cases, a person may require a mixed size of tips for a proper, comfortable t (Ex. Small
for Right ear and Medium for Left ear).
A good t is important: it means you are properly protected. A poor t will drop sound quality and will aect
your overall team’s quality of communication adding background noise or low volume output.
NOTE: To avoid dropping your device while tting your earpieces, hold the amulet in one hand and in the other
hand the earpieces. Hang it over your neck, or attach it to your clothing while attaching the amulet. This way
you can safely insert the earpieces and adjust the securing mechanisms (bolo and clip). With your amulet
attached, separate your Right from your Left earpiece by swinging your Left earpiece to the left side in front
of you.
Good t: right size conforms
to canal and creates an
acoustical seal.
Bad t: wrong size – doesn’t
expand to ear canal.
