If you’re a proud Apple Watch owner that’s passionate about swimming and you’re looking for a swimming audio system that allows you to listen to your soundtracks during your swimming session, then the H2O Audio Interval Swim Headphones for the Apple Watch is made for you.
The Interval is the only waterproof headphone system currently available for the Apple Watch, and it was designed just for swimmers. Thanks to the Interval swimmers can finally enjoy their workouts with music, just like runners, gym enthusiasts and many other athletes have been doing for years!
The H2O Audio Interval Swim Headphones for Apple Watch is designed by H2O Audio, a company that’s based in San Diego, California. H2O Audio develops accessories for portable media players, counting with over 15 years of experience developing waterproof products for swimmers. During 2008, H2O Audio was one of the top 500 fastest growing companies in the United States.
Now, let’s take a look at everything that the H2O Audio Interval Swim Headphones for Apple Watch has to offer.
DESIGN & SPECS
The H2O Audio Interval Swim Headphones are designed to get the most out of the Apple Watch while swimming. This Audio system is relatively small and fully waterproof, meaning you can even use its simple, multi-action 3-button interface when going underwater (more on its interface later). The system is extremely easy to use, offering a quick setup and a ton of quick-access controls via its 3-button interface.
It’s super easy to attach your Apple Watch to the Interval, as you’ll see later in the article. The system is compatible with the Apple Watch Series 2, 3, 4 and 5, fitting all Apple Watch sizes (38mm, 40mm, 42mm and 44mm).
The Interval Swim Headphones’ design features 2 horizontal metal pins (one at the upper part and one at the lower part), which are attached to each of your Apple Watch’s groves. The picture embedded below shows an example of the installation.
After snapping your Apple Watch onto the system, it is also extremely easy to attach the Interval Swim Headphones to your swimming goggles, taking you only a few minutes to get everything up and running. The Interval Swim Headphones features a simple “double-hook” design (found on the sides), making it easy for you to attach the Interval to any pair of swimming goggles.
To attach the Interval to your swimming goggle just gently stretch your goggles’ strap and slide it through the bottom of the hooks. You should end up with your goggles’ strap right behind your Apple Watch.
The Interval Swim Headphones system for the Apple Watch comes with built-in waterproof Surge S+ headphones – meaning they are non-removable – that are equipped with neodymium drivers.
The Interval Swim Headphones also feature H2O Audio’s Patented waterproof headphone technology, which provides you with superior sound, even when you’re swimming underwater. This allows you to enjoy high-quality bass sounds even when going underwater at the deepest part of the swimming pool.
At the front of the device (on the lower right) we can find an LED indicator that informs users about the Interval’s status. Users will see a Static Red LED when recharging the device, a Rapid Flashing Red and Blue LED when pairing the Interval to the Apple Watch via Bluetooth, and a Slowly Flashing Blue LED after Bluetooth pairing is established.
BATTERY, BATTERY LIFE & Charging
The Interval Swim Headphones come equipped with a built-in rechargeable battery that can offer up to 6 hours of battery life when used at full volume.
Recharging the Interval is fairly simple. All you have to do is open its USB port cover (located at the back of the device, on the lower right side), and connect the Interval to the included Micro USB Charging Cable. After that, the Interval’s LED indicator will light up with a bright Red color while it’s charging, having its LED color changing to Blue when reaching a full charge.
CONNECTIVITY
The Interval Swim Headphones use a Bluetooth 5.0 chipset for audio clarity and streaming reliability.
Connecting the Interval Swim Headphones to your Apple via Bluetooth 5.0 is extremely easy. All you have to do is go to your Apple Watch Settings and select Bluetooth. After that your Apple Watch will start searching for any other nearby Bluetooth devices. Then all you have to do is press and hold the center button of the Interval (needs to be Powered Off) for around 8 seconds, and the Bluetooth pairing will be established.
WHAT’S IN THE BOX?
Inside each H2O Audio Interval Swim Headphones package users will find: one Interval Swim Headphones system (with built-in Surge S+ headphones), one included Micro USB Charging Cable, and a total of 8 earplug sets in 2 different styles (5 classic ear tip sets in different sizes (XS-XL) and 3 “tree” tip sets in different sizes (S-L)).
All these different earplug pairs help you get the possible fit. Plus, they made with high-quality materials and are extremely comfortable to wear.
INTERVAL’S MULTI-ACTION INTERFACE – HOW TO USE?
As said before, the Interval features 3 simple multi-action buttons that allow for a ton of quick and easy actions.
Center Button
Pressing and holding the center button (also known as a “Long Press”) for a couple of seconds allows you to turn the Interval On or Off. Tapping the center button (performing a “Short-Press”) allows you to play or pause your music. As state before (on the Connectivity section), the center button is also used to enter the Bluetooth Pairing Mode.
If your Apple Watch has cellular connection, double clicking the center button will initiate a call to your last dialed phone number.
(-) Button (Left Side) and (+) Button (Right Side)
Short-Pressing or tapping either of these buttons will allow you to reduce (- button) or increase (+ button) the Interval’s volume. Long-Pressing or tapping either of the buttons will allow you to skip a track backwards (- button) or forward (+ button).
If you want to know more on how to setup and use the Interval Swim Headphones, the company’s Quick Start Guide Video will teach you everything you need to know.
COMPATIBLE WITH ALL YOUR FAVORITE AUDIO APPS
The Interval Swim Headphones are compatible with any Audio App you can think of, but be aware that some of those Apps might require a premium subscription before working on your Interval.
The Interval is compatible with the Apple Music App, Apple Books (Apple’s Audio Books App), the Pandora App (Internet Radio Statio), and many more.
SWIM TRACKER APP – STATS TRACKING & COACHING
The Interval Swim Headphones can further enhance your swimming experience after you pair the system with the Swim Tracker App (free iPhone and Apple Watch App).
The Swim Tracker App allows you to log all of your swims so you can keep track of your distances and PRs. The App also lets you get audio lap counting and coaching to easily reach your goals.
Lastly, if you’re a competitive person, you can also compete with any of your friends or family members. All you have to do is connect your Interval to the Apple Health App.
