Achieving the Best Fit  
Maintaining Your Headphones  
About Your Headphones  
To get the best performance out of your Surge Pro Waterproof Headphones 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.  
Your H2O Audio Surge Pro Headphones are completely waterproof. After any activity  
involving heavy perspiration, in-water usage, or inclement weather, you can rinse off your  
headphones with clean water and let them air dry for your next use.  
By incorporating H2O Audio’s patented waterproof technology with the same  
high-performance, balanced armature drivers found in hearing aids and professional sound  
studio monitors, Surge Pro Waterproof Headphones deliver highly accurate sound  
reproduction in a compact size that is perfect for active use in any environment. Surge Pro  
Waterproof Headphones feature a wide variety of earplug sizes and styles designed to  
isolate ambient noise and create a watertight seal.  
Here are a few tips we’ve discovered through feedback from our customers:  
FAQs  
Push the earplugs into your ear canals far enough to establish a secure fit but not so far  
they become uncomfortable.  
1. My new Surge Pro Waterproof Headphones sound distorted right out of the box. What  
should I do?  
Includes:  
• 5 pair of black elastomer earplugs: XS, SM, MD (Installed), LG, and XL  
• 2 pair of black foam earplugs: S/M and M/L  
A tighter seal may be achieved by pulling your upper ear back while inserting the  
earplugs.  
Surge Pro Waterproof Headphones have 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.  
You may find it preferable to use different size earplugs for each ear.  
The insides of the black elastomer earplugs are labeled to aid in identification. Flip them  
inside out to identify sizes.  
For optimal in water performance, the earplugs should completely seal your ear canals:  
Playing the headphones at 90% volume for 30 minutes 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. If your headphones do not equalize or if you have any  
questions, please contact H2O Audio Customer Service.  
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.  
Additional tips for swimmers:  
2. The sound is intermittent from my headphones. How can I fix or replace them?  
Wrapping the headphone cables around your swim goggle straps before placing them in  
your ears can help secure a better fit.  
Ensure the waterproof headphones are plugged in completely. If the problem still  
continues please contact H2O Audio Customer Service.
