EARSET CUSTOM FITTING
Left or Right Ear Placement
The Wi Sure-Fit™ EL Series can easily be converted from right
to left ear wearing preferences with a Simple-Twist™. This un-
matched time saving feature delivers exceptional fl exibility
for venues needing to accommodate multiple users and their
wearing preferences.
1. Press the boom locking switch located on the bottom
of the Silicon ear mount.
2. Rotate the boom 180 degrees to the preferred
ear wearing preference.
3. Release the locking switch when rotation is complete.
No need to rework the bend or reshape the boom again when
switching from left to right ear placement. The boom maintains
its original angle to capture vocals from the near-the-mouth
position, from the opposite side.
Page 21
Wearing the Wi Sure-Fit Earset
The Wi Sure-Fit™ EL Series advanced ergonomic Silicon ear-mount design
delivers an unmatched comfortable fi t in seconds while ensuring secure boom
placement even when the head moves, or when used with glasses or other
head-worn accessories. This ultra-lightweight MIC is incredibly easy to
wear even for an extended time.
1. Pull the “C” shaped Sure-Fit™ silicon ear mount wide open and
clip over the ear
2. Loop the bottom part of the “C” shaped ear mount beneath the earlobe.
3. You should feel the Wi Sure-Fit earset gripping your ear and pressing
out against your earlobe for comfortable secure fi t.
4. The boom is designed to press and curve smoothly around the face.

Adjusting the Boom Length
The Wi Sure-Fit™ EL Series boom can easily be adjusted to
the appropriate length and placement with a simple push of a
button to capture the closest near-the-mouth vocals clearly
and consistently. The boom locking mechanism keeps the
boom securely in place to provide good gain and natural
sound that doesn’t change when the head moves.
1. Press the boom locking switch located on the bottom
of the Silicon ear mount.
2. Slide the boom shaft to position the MIC capsule
just behind the corner of your mouth when you are
smiling.
3. Release the locking switch when adjustment is complete.
• Placing the microphone too far forward
can result in breath-related pops.

Adjusting the Boom Curve
The Wi Sure-Fit™ EL Series bendable boom can easily be adjusted
to position the microphone tip as close as possible to the mouth for
best vocal gain and clarity. Adjust the curvature of the boom only
when necessary. If the microphone tip is away from the cheek, this
will result in lower gain and more ambient noise.
1. Using the thumb and the index fi nger, curve the boom with
a sliding motion to form the boom and get the curvature you
require.
• Avoid bending right at the capsule
• Do not bend the boom over sharp edges such as
the end of your fi ngernail
• Do not pinch, twist or kink the boom around a tight
radius less than 1/2” diameter

Positioning The Microphone Capsule
The Wi Sure-Fit™ EL Series removable microphone capsule is located at the tip of the boom. The key to maximizing
the sound quality is to locate the capsule as close as possible to the mouth without touching the face.
1. Press the boom locking switch located on the bottom
of the Silicon ear mount.
2. Slide the boom shaft to position the MIC capsule
just behind the corner of your mouth when you
are smiling.
3. Release the locking switch when adjustment is complete.
• Placing the microphone too far forward
can result in breath-related pops.
• Use the windscreen outdoors.

Using The Earset/Lavalier Cable Clip
The Wi Sure-Fit™ EL Series comes with an Earset/
Lavalier cable clip to prevent movement of the cable
from dislodging the earset. The clip is specifi cally
designed to match the diameter of your cable, either
1.4mm or 2mm.
1. Locate the cable clip and gently pull the cable
down into the rubber cable channel opening on
the clip.
2. Attach the clip to the collar and leave enough
slack in the cable such that the head can turn to
both sides without tugging on the clip.
• We recommend leaving the clip attached
to the cable when possible to minimize
repetitive strain on the cable.

interchangeable between the earset and the lavalier for minimum
visibility with maximum fl exibility.
1. Remove the MIC capsule from the earset or lavalier MIC port
by unscrewing the MIC capsule counterclockwise.
2. Align the MIC capsule threads in a straight line with earset or
lavalier cable MIC port
