Delphin: Run & Swim with ANY APP without your phone



What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

THE DELPHIN (Patents Pending)

Just as the Delphin served as the greatest wingman of all time for the god of the sea, today's Delphin serves as the greatest workout companion of all time for runners tired of carrying around their phone and every swimmer tired of the lap swimming grind. With the Delphin, you can finally use your favorite apps in the pool. As a wearable touch-screen device with Wi-Fi and Bluetooth capabilities, the Delphin operates underwater and on land without a phone. It features access to apps, external buttons for navigating playlists and volume, and a unique design tailored for maximum portability. This wearable makes your swimming workout a joy.

Uses the same apps:

  • Spotify (Spotify Premium required for offline listening)
  • Pandora (Pandora Plus required for offline listening)
  • Audible
  • Google Music
  • SoundCloud
  • Netflix
  • Podcast and Radio Addict

Download your content wirelessly:

Wirelessly download content by simply connecting to the WiFi hotspot at home, work, or your pool. Use the same playlists you already created on Spotify or the stations you created on Pandora. Download and sync your Audible audiobooks to the same spot you left off reading or listening to on your phone (No more attempts to fast forward through audiobooks).

Compatible with wired or Bluetooth headphones:

With any of the reward levels that include a Delphin, we’ll send you your choice of waterproof headphones to go with it (after the campaign, we will send a survey and ask if you would like to change your Delphin reward to include Swimbuds Bluetooth instead of Swimbuds Sport). Swimbuds Sport Waterproof Headphones have an advanced design for the best possible sound underwater. Multiple sizes and styles of earbud tips are guaranteed to help you find a good seal for any ear. Swimbuds Bluetooth Waterproof Headphones are the first waterproof bluetooth headphones designed for use when actually submerged. Water distorts bluetooth signals too much for headphones to work when separated from the source of the signal. The Delphin solves that by being 100% waterproof and small enough to clip on your goggle strap. Both headphones work great above water as well!

Record your laps and times (If we meet our stretch goal of $100,000!): 

Receive audible reminders of your lap count and split times at a frequency you decide. Made for swimmers, the Delphin will help improve your performance by enabling you to document and automatically track your laps and times so that you can keep pushing your limits. Sync your workouts with and compare your swims with the entire community!



The Delphin has a small touch screen that enables you to access your favorite apps. You can navigate the touchscreen just like you would your phone. The Deluxe Bundle Kickstarter Rewards also contain a Bluetooth keyboard, which can be easily synced to your Delphin for even easier navigation.

The Delphin has up to 4 hours of battery life, outlasting your longest swim or workout. Need more battery life? You can always use the 5,000 mAh power bank included in the deluxe bundle to recharge your Delphin up to 8 times before you need to plug it in. Leave your Delphin charging in your locker between swims and only charge your Power Bank once a week!

The built-in clip makes it easy to attach your Delphin to your goggle strap, swimsuit, or shorts and at only 1.6 ounces, you’ll barely feel it.

The rubberized edges of the device are designed to be durable and withstand a rugged environment. The Delphin can be dropped, fumbled, or even thrown in the ocean.

What makes the Delphin AMAZING?

Currently, there’s no good way to listen to your favorite music apps like Spotify or Pandora while you swim or run. If you run outside, you have to carry around a huge smartphone. If you want to swim and listen to music, you’ve got to risk putting your phone in a waterproof case (that might not be 100% waterproof) and strap it to your body.

Sure, devices like Underwater Audio's waterproof MP3 players work great, but who owns their own music these days (ever heard of Spotify)? If you want to listen to an audiobook, you’ve got to download it and transfer it--a process that’s slow, antiquated and clunky. Engineers designed MP3 players in the 1990's for interfacing with PCs. The Delphin will finally take the apps you use for your workouts in this century from a phone the size of a brick and place them carefully into a device the size of a saltine cracker (see Christian eating a saltine below).

Brick sized anything is no fun.

Who should use the Delphin?

The Delphin provides a much cleaner experience for swimmers and runners. With way more storage and the ability to connect to WiFi wherever you work out, the Delphin offers much more convenience and functionality.

Swimmers and other athletes will appreciate the Delphin for acting as a tool to improve performance, endurance and speed. You can use it to track your laps and times, to stay energized and maintain focus when the pressure is on and you need to take the edge off.

Anyone uncomfortable with a $20 waterproof case protecting their $800 phone can trust the inherently waterproof Delphin. It can withstand the worst spills, full immersion for extended periods, and most extreme cases of weather.

Anyone recovering from an injury and not used to spending so much time in the pool needs a Delphin. Music can help someone more easily transition to working out in the pool if they use music while they workout at the gym.

Why do I need the Delphin?

If you already exercise, you probably listen to music while you run or hear the upbeat playlists blasting at your local gym. This music helps with more than just having fun or ambiance. Getting “pumped up” has real effects on the human brain.

All of us probably remember the images of Michael Phelps in Rio with his game face on and his earbuds in. Music can actually increase our heart rate and breathing so that we leap into action both mentally and physically.

Music helps us disassociate. When you listen to music while you exercise, disassociation helps you become less aware of the pain and the fatigue that your body experiences, enabling you to go that extra set. With swimming specifically, music can also help you synchronize your movements. When that happens, you actually use your oxygen more efficiently and give yourself a better workout.

Ultimately, music can play a key role in your results whether you exercise to recover from an injury or you train to compete in an upcoming race. The Delphin enables you to easily access all of your favorite music on a device that will not get in the way of your swim.

Who is Underwater Audio?

Underwater Audio started five and a half years ago out of a true need for a solution. Todd hurt his back in a car accident and began swimming for physical therapy. With 25 years of experience as an engineer, he decided that there should be a better way to listen to music while you swim. He then asked his son, Scott, a marketing major at the time, to help him with his idea to start a company. They spent the last five and a half years testing various methods to bring music underwater and make it just as easy as listening to music on your phone. After some probably not-so-safe experiments involving transmitters and water, they’ve come to the conclusion that radio waves and water don’t mix. Scott and Todd ultimately solved the problem of streaming music by avoiding the issue altogether. The Delphin enables swimmers to download their music onto the device for offline listening and swim with music to their heart’s content.

Although we won't be held liable for fixing up Poseidon's sketchy romances like the Delphin of old, we will bring you music from Spotify, books from audible, and even tell you your lap count while you swim. We spent the last few years developing the Delphin in order to make your swim, your run, and any other part of your workout more fun. Make your pledge today, and don't miss the Delphin wave. Thank you!

Risks and challenges


Underwater Audio has already built a working prototype of the Delphin and has begun preparing for production. We expect the Kickstarter campaign will help us better understand the demand for the Delphin and pay for production tooling.

The biggest challenge we foresee is the ability to meet the quickly growing demand for the Delphin in an organized and timely manner.
