About Your Headphones
The Flex Sweatproof Waterproof Sport Headphones are perfect for use almost anywhere.
Whether you’re in the water, near the water or just looking for a durable, easy to clean
headphone, the Flex will make sure you never miss a beat. No matter how many flexes of
your arm, gallons you sweat or miles you run in the rain, Flex sport headphones will
continue to deliver great sound.
Flex sport headphones have a depth rating of 3ft for 30mins. For longer duration
underwater at deeper depths we suggest our Surge Waterproof Sport Headphones with
bass amplified sound and a depth rating of 12ft for an unlimited amount of time.
Flex Waterproof Sweatproof Sport Headphones Include:
• 3 Pairs of earplugs: SM, MD (Installed) and LG
• 1 SealTight Adapter, for use with H2O Audio Waterproof Armbands and Cases.
For more earplug options check out the Pro Fit Kit, which includes nine sets of earplugs in various styles and
sizes, purchased separately at www.H2OAudio.com.
Achieving the Best Fit
To get the best performance out of your Flex sport headphones it helps to take the time to
ensure a proper fit. We encourage you to experiment with different earplug sizes and
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.

FAQs
1. What happens if my Flex Sweatproof Waterproof Sport Headphones fall out of my ears
while in the water?
Flex Sweatproof Waterproof Sport Headphones are 100% waterproof and can be exposed
or submerged in 3 feet of water for up to 30mins. If the headphones come out of your ears
and fall into the water, simply shake or blow off any water that remains in the front of the
headphone to ensure the best sound experience.

Safety Information
Please read this manual carefully. If you have any questions please contact H2O Audio
Customer Service prior to use.
Improper use of this system may cause the user to make mistakes or decisions that may lead
to serious injury or death. Headphones should never be used for SCUBA diving.
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
sound. 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.
It can be potentially dangerous to use headphones while engaging in activities that require
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
