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.
Flex headphones and H2O Audio Waterproof Armbands and Cases
To connect your Flex Sweatproof Waterproof Sport Headphones with H2O Audio’s
Waterproof Armbands or Cases (sold separately) you may have to install the included
SealTight Adapter, designed to create a waterproof connection between the Flex
headphones new small strain relief and H2O Audio Armbands and Cases.
Please follow these steps to verify that you need to install the SealTight Adapter:
1. Plug headphones into your H2O Audio Waterproof Armband or Case.
2. If there is an obvious gap between the SealTight Boot on your H2O Audio armband/case
and the headphone strain relief, then you must install the SealTight Adapter.
3. To install the SealTight Adapter, push the Strain Relief through the Adapter, with the
external rib of the Adapter closest to the top of the Strain Relief.
4. When properly installed, the bottom of the strain relief and the bottom of the SealTight
Adapter should be flush.
5. With the SealTight Adapter installed plug headphones into your H2O Audio Armband or
Case and ensure the top of the Adapter and the top of the Boot are flush.
