ACHIEVING THE PERFECT CUSTOM FIT
To get the best performance out of your headphones it helps to take the time to
ensure a proper fit. We encourage you to experiment with different earplug sizes
and styles until you find the combination that sounds and fits best.
Different Ways to Wear:
Over the Ear with a Stabilizing Hook
Each earbud is marked with an R for right and L for left channels.
When wearing Momentum Custom Sport Headphones over the ear the
R earbud should be inser ted to the right ear and L earbud into the left.
Creating the Perfect Stabilizing Hook
01. Shape Moldable Memory Wire
into an ear hook shape.
02. Ensure correct ear tips are installed,
insert earbud in your ear and guide the
formed hook around your ear.
WRAP WIRE
OVER EARS FOR A
STABILIZING HOOK
03. Readjust the shape of hook so it
fits snugly around your ear.
Your new customized hook
will retain its shape for future use.
Bend Away and Behind or Simple and Straight
Although Momentum Custom Sport Headphones are
designed to be worn over the ear, they can be worn
like normal headphones. Ensure the Moldable
Memory Wire is fully straightened out or bend
memory wires behind and away from your face.
Moldable Memory Wire
Our unique Moldable Memory Wire reduces
cordphonics and keeps headphones in place even
during the most vigorous activates.
BEND WIRES
BACK AND OUT
OF THE WAY
WEAR WIRES
SIMPLE AND
STRAIGHT
Memory Wire is designed to stay flexible, so it can be
reshaped for maximum comfort and stability during
everything you do.
Tips for the Best Fit:
• Push the ear tips into your ear canals far enough to establish a secure fit but
not so far that they become uncomfortable.
• A tighter seal may be achieved by pulling your upper ear back while inserting
the ear tips.
• You may find it preferable to use different size ear tips for each ear.
• A looser fit will increase the amount of ambient noise heard but decreases
the bass. To increase the bass heard, experiment with the various ear tips
sizes/styles to achieve a tight but comfor table fit.
REFLECTIVE FOR SAFETY
X-1’s patent pending retro reflective cable provides added safety by making you
more visible to others in low light environments.
MAINTAINING YOUR HEADPHONES
Your Momentum Custom Sport Headphones are completely Weatherproof and
Sweatproof. After any activity involving heavy perspiration or inclement
weather, you can rinse off your headphones with clean water and let them air
dry for your next use.
IMPORTANT: Please note that Momentum Custom Sport Headphones
are NOT 100% Waterproof and NOT intended for in-water use and/or

SAFETY INFORMATION
Please read this manual carefully. If you have any questions please contact X-1 Customer
Service prior to use.
Improper use of this system may cause the user to make mistakes or decisions that may lead to
serious injury or death.
Always make sure to have the audio player volume turned to zero and the headphones turned
away from the ears when turning on the audio player. If the volume level is not zero when the
audio player is turned on, it may cause ear injury due to a sudden burst of volume. The volume
should be slowly increased with an audio track playing to set the speaker volume to comfortable
output levels prior to positioning the headphones next to the ears. Hearing experts advise
against continuously loud and extended play. If you experience ringing in your ears, reduce
volume or discontinue use.
It can be potentially dangerous to use headphones while engaging in activities that require your
full attention. You should exercise extreme caution or discontinue use in potentially hazardous
situations. Do not use the headphones while driving, cycling, or operating any motorized vehicle.
It may create a traffic hazard and is illegal in some areas. Those users that elect to utilize this
system at, or near, the water’s surface, must maintain safety awareness of moving water crafts.
WARNING: Ear tips should always be used.
