Checking the Waterproof Seal  
Achieving the Best Fit  
Wearing Your Interval  
Controlling Your iPod shuffle  
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.  
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.  
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.  
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.  
Waterproof Seal  
A tighter seal may be achieved by pulling your upper ear back while inserting the  
earplugs.

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.  
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:  
The Interval is controlled in the same manner as your iPod shuffle  
Insert earplugs before your ears get wet to achieve the best watertight seal.  
Play or Pause Click the Center Button  
Swim goggle strap should be  
attached to the Interval as shown  
Do not attach swim goggle  
strap over the front of the Interval  
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.  
If you have any concerns please contact  
H2O Audio Customer Support.

FAQs  
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.

What should I do?

The Interval Waterproof Headphone System has sealed, watertight speaker chambers.  
During initial use, your headphones may sound distorted or operate at a low audio level  
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.

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

problem still occurs, wait 24 hours and test again as the headphones will usually equalize  
within a short period of time. If your headphones do not equalize or if you have any  
questions, please contact H2O Audio Customer Service.
