2. The sound is intermittent from my headphones. What should I do?
Ensure the audio jack inside of the Interval is plugged into the shuffle completely. If the
problem still continues please contact H2O Audio Customer Service.
3. What happens if my headphones fall out of my ears while in the water?
The Interval Waterproof Headphone System is 100% waterproof and can be
exposed/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.
Wearing Your Interval
The Interval Waterproof Headphone System 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.
Headphone cord can hang below or over the ear and may be tucked under a swim cap.

Achieving the Best Fit
To get the best performance out of your Interval Waterproof Headphone System it helps to
take the time to ensure a proper fit. We encourage you to experiment with different
earplug sizes, styles, and the angle of insertion until you find the combination that sounds
and fits best.
Here are a few tips we’ve discovered through feedback from our customers:
Push the earplugs into your ear canals far enough to establish a secure fit but not so far
they become uncomfortable.
A tighter seal may be achieved by pulling your upper ear back while inserting the
You may find it preferable to use different size earplugs for each ear.
For optimal in water performance, the earplugs should completely seal your ear canals:
Insert earplugs before your ears get wet to achieve the best watertight seal.
Larger size earplugs may be preferable during active and/or in water use as they may
offer more contact with the ear and 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.

Checking the Waterproof Seal
The Interval Waterproof Headphone System 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 to 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.
If you have any concerns please contact
