Surge Waterproof Headphones feature 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 insides of 

the earplugs are labeled to aid in identification.

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 

preferable 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 earplugs 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 

with the ear and may improve the watertight seal.

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.

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 for further instructions on 
how to receive replacement headphones.

3. What happens if my Surge Headphones fall out 
of my ears while in the water?
Surge Headphones are 100% waterproof and can be 
exposed / submerged in water for unlimited time 
periods. However, 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.

1. My new Surge Headphones sound distorted 
right out of the box. What should I do?
Surge Headphones feature sealed, watertight speaker 
chambers. During initial use, your 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 headset 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.
