1. What happens if my headphones fall out of my ears while in the water?
The Interval is 100% waterproof and can be exposed or submerged in water for
an unlimited amount of time. If the headphones come out of your ears and fall
into the water, simply shake or blow off any water that remains in the earplug to
ensure the best sound experience.

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.
WARNING: Contains small parts which may be a choking hazard.
Not suitable for children under 3 years old.
WARNING: This product contains magnetic material.

Headphone cord can hang below or over the ear
and may be tucked under a swim cap.

• You may find it preferable to use different size ear tips for each ear.
For optimal performance in water, the ear tips should completely seal
your ear canals:
• Insert ear tips before your ears get wet to achieve the best watertight seal.
• The tree tip or a larger size ear tip may be preferable during active and/or in
water use as they may offer more contact with the ear for a tighter seal.
• Wrapping the headphone cables around your swim goggle straps before
placing them in your ears can help secure a better fit.
• The headphones may stay in place more easily if they are tucked
underneath a swim cap.
WEARING YOUR INTERVAL
The Interval is designed to be
worn on the back of the head,
attached to a swim goggle
strap. The case can be installed
on the top or bottom goggle
strap and can be worn high or
low on the head depending on
preference.
The Interval features a wide variety of ear tip sizes designed to create a watertight
seal and provide a comfortable, secure fit. Includes:
• 5 pair of blue elastomer earplugs: XS, SM, MD (installed), LG, and XL
The insides of the blue elastomer earplugs are labeled to aid in identification. Flip
them inside out to identify sizes.
• 1 pair of black small tree tip earplugs for swimming, or if you have trouble
keeping earplugs in your ears.
Here are a few tips we’ve discovered through feedback from our
customers:
• 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.

ACHIEVING THE BEST FIT
To get the best performance out of your Interval Swim Solution it helps to take the
time to ensure a proper fit. We encourage you to experiment with different earplug
sizes and the angle of insertion until you find the combination that sounds and fits
best.

CHECKING THE WATERPROOF SEAL
The Interval features a removable waterproof seal that forms a waterproof barrier
between the base and lid of the case. It is extremely important that special
attention is paid to ensure the seal is completely seated in the groove of the lid. If
the seal is loose, out of alignment, twisted or pinched in any way, it will
compromise the waterproof integrity of the case and should not be used.
Any debris such as hair or sand will keep it from forming a
watertight barrier and should be cleaned off before use.
CAUTION: If the seal comes out of
alignment, carefully place it in the groove,
ensuring all 4 corners are correctly installed.
Compress the lid into the base and then
re-open it to make sure the seal is fitted
correctly into the groove. The seal should
appear straight and uniform along the edge
and should not fall out easily.
