About Your Headphones
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.
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
The insides of the black elastomer earplugs are labeled to aid in identification. Flip them
inside out to identify sizes.
Maintaining Your Headphones
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.
FAQs
1. My new Surge Pro Waterproof Headphones sound distorted right out of the box. What
should I do?
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.
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.
2. The sound is intermittent from my headphones. How can I fix or replace them?
Ensure the waterproof headphones are plugged in completely. If the problem still
continues please contact H2O Audio Customer Service.
3. What happens if my Surge Pro Waterproof Headphones fall out of my ears while in the
water?
Surge Pro Waterproof headphones are 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.
Achieving the Best Fit
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.
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
earplugs.
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.
Additional tips for swimmers:
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.
