Important Seal Information
Installing the shuffle into the case
The Interval Waterproof Headphone System features a removable silicone 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 silicone 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.

Open Case
Caution: If the seal comes out of alignment, carefully place it in the groove, ensuring all 4
corners are correctly installed. Compress the lid 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 its’ edge and should not fall out easily.

FAQ’s
Using Your Headphone System
1. My new H2O Audio Interval Waterproof Headphone System sounds
distorted right out of the box. What should I do?
The Interval Waterproof Headphone System features ergonomic earplugs designed to
isolate sound and provide a watertight seal. The headphones are packaged with medium
earplugs installed. Extra small, small, large and extra large earplugs are also included.
The waterproof headphones feature sealed, watertight speaker
chambers. During initial use, the headphones may sound distorted or
operate at very low audio levels due to a vacuum formed in the speaker
chamber during air travel or shipment. Volume and sound quality will
return to normal once the pressure equalizes. Playing the headphones
at 90% volume for 30min typically solves this problem. If the problem
still occurs, wait 24 hours and test again as the headphones will usually
equalize within a short period of time.
The earplugs should be pushed into your ear canals far enough to establish a secure fit but
not so far that they become uncomfortable. Some users may find it perferable to use
different size earplugs for each ear.
For optimal performance, the earplugs need to completely seal with the walls of your ear
canals. Modifying the earplug size and its angle of insertion are important steps in creating
a watertight seal.
Larger size earplugs may be preferable during active and / or in water use as they may offer
more contact wth the ear and may improve the watertight seal.
2. The sound is intermittent from my headphones. How can I fix or replace
them?
Ensure the audio jack inside of the shuffle case is plugged into the
shuffle completely. If the problem still continues please visit
on how to receive a replacement.
A watertight seal is best achieved when the earplugs are inserted into your ears when dry.
If your ear canals are wet, you may find larger earplugs provide a better seal.
We encourage users to experiment with different earplug sizes until they find the
combination that works best for them.
Wearing Your Headphone System
3. What happens if the 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 unlimited time periods. How-
ever, if the headphones come out of your ears and fall into the water,
simply shake or blow off any surface water that may remain in the
earplug. This will help ensure the best sound experience.
