      I have to be honest with you, swimming is hard for me. I swim solo and the monotony of swinging arms and following the black line from one end of the pool to the other just isn’t fun. Doing it a hundred times in a session is even less fun. But in order to improve, I have to keep swimming more and find some enjoyment in it. Over the years I’ve discovered that listening to music while swimming made all of the difference.

    • VilTri

      My first mp3 player was the Finis Neptune. It worked, but after doing a few sessions with it I put it away and didn’t use it since. The main issue for me was the audio quality it just wasn’t good. The music sounded muffled and almost no bass at all. They transmit sound through the jawbone instead of the ear canal so most of the sound details get lost. I found them to be good enough to listen to an audiobook or a podcast, but not for listening to music.

      Then I found the Underwater Audio players. I tried the Syryn and iPod Shuffle (4 of them) until I saw their Kickstarter project called Delphin. I was sold on the idea, but it took more than 2 years of development to have it shipped to my doorstep. I got mine just over a month ago and had a few swims with it.

      Perhaps the best thing about the Delphin is having a touchscreen display. The LCD screen is a bit hard to see in a direct sunlight, but otherwise it is plenty bright and very sharp. The colors look great too. The tiny screen allows for a quick navigation to my favorite playlists and audiobooks. In fact, the screen is tiny to a fault. It takes some patience and dexterity to navigate. My player came with a touchscreen pen, which simplifies this process with a more precise touching, but it is yet another thing to carry and lose. I’m hoping that the next version of Delphin would have a slightly bigger screen.

      The next best thing is having fully functional apps. Delphin runs on an Android operating system and I’ve installed my favorite Spotify and Audible apps. The ability to seamlessly sync playlists in Spotify and download songs directly to the device is a game changer. No longer do I need to manage my playlists in iTunes and have my iPod Shuffle connected with a cord to download songs. As long as the Delphin is connected to a Wi-Fi network it will download my latest favorite songs in the background. 

    • VilTri

      Listening to the audiobooks is much simpler too. I just fire up an Audible app and download the latest books. It also automatically syncs the chapter I am on, so I can continue listening where I left off. It is also super easy to manage books on the go.

      Before I jump in the pool I have to select which music or audiobook I want to listen to. Once the water touches the screen it becomes very hard to do anything. Just like with any capacitive screen, drops of water confuse the device locking it up from navigating the screen until all water drops have been wiped off. Even the Apple Watch and iPhone X suffer from this fate. Fortunately Delphin has physical buttons to play / pause / skip songs and increase or decrease volume. So I have to remember to turn off the screen before jumping in the pool.

      The case is very rugged and after dropping the player multiple times while fiddling with it, it still looks like new. The rubberized plastic bumper extends slightly beyond the screen protecting the glass LCD screen from shattering. The buttons on the side of the case are super small. I wish they would have been slightly bigger and have more feedback when pressing. While in the pool it is hard to feel them with cold fingers. But this isn’t a big issue once you get used to it.

    • VilTri

      When I use the player outside of the pool it gets noticeably warm. That is normal, but takes time to adjust to since none of my other mp3 players get this hot. Delphin has a Bluetooth connection and I discovered that wirelessly pairing it with my Jaybird Freedom 2 headphones makes for an easy hands-free run. I have to make sure to clip the player to a hat or visor so it stays right next to the headphones. If they are too far away from each other, the signal breaks up. Another cool thing I’ve discovered is that I can start listening to the music on the way to the pool via Bluetooth headphones then plug in underwater headphones and continue listening while I’m in the pool.

    • VilTri

      The most important thing about listening to the music underwater is having a good seal between headphones and the ear canal. With a proper seal, the headphones sound great having an adequate bass and plenty of mids and highs. The Delphin comes with a ton of different headphone tips to choose from and I found that only one of them actually works for me. I had to spend some time to test them all in the pool to see which ones have the best seal. As a bonus they also protect my ears from water just like regular ear plugs, so my ear canal stays water free and I can listen to the music at the same time. How cool is that?!

    • VilTri

      So far I’ve had a few swims with the Delphin. With each session I learn something new about the player and the headphones. For example, selecting headphone tips for a proper seal can only be done in the pool since moving through water will expose all of the subtle differences between each tip. I also had to allocate a good amount of time for the initial installation of apps and syncing of the music and audiobooks. It seemed like a big upfront investment, but it is worth it in the end. Swimming with music really helped me swim better. I now enjoy the workouts more and swim more.

      Please ask any questions about the player, headphones and swimming with them. If you have one, I’d love to know what you like and don’t like about it too.

      Since the player is Android based, there is no direct sync between it and the iTunes. You can, however, export songs you've bought via iTunes and import them manually. Alternatively you can listen to a Pandora or YouTube Music app. Essentially any app in Google Play Store will work on this player.

      Great write up! I am one of the founders of Underwater Audio. If you have an Apple Music subscription, you can actually use the Apple Music app for Android (weird that it exists, I know) to sync with iTunes. You can also do as VilTri suggests and drag and drop your iTunes files onto the Delphin. Unlike most MP3 players, the Delphin will play aac files, which are the default file type for iTunes. Also, YouTube music is actually one of the few apps that doesn’t work on the Delphin. If there is a specific app that you want to find out about, let me know!

      Last pro tip - we recently discovered that Google’s handwriting input keyboard makes typing on the Delphin much less frustrating. You can download it by going to “Get Apps” app on the Delphin in the “More apps” link.

      That is a hard question for me to answer since I've never fully drained a battery in a session. My swim sessions are under 1 hour long and I recharge the player every 2-3 session. This way I know for sure there is enough juice for the next one. Although looking at the spec Delphin is advertised to last as long as 6 hours without the screen on.

      @Scottecwalker1 can answer your question better since he is one of the founders of Underwater Audio. He chimed in earlier in a conversation, but I'll ping him to clarify.

      Thank you for asking this question, I totally forgot about mentioning battery life in the post!

    • VilTri

      Scott,

      Could you talk about the battery life a bit? I usually recharge mine after 2-3 sessions (each under 1 hour). Also, what are the best tips to keep the charge in between sessions. I try to fully shut down the player, but it seems that there is some battery charge drop the next time I power the Delphin.

      Thank you!

      VilTri,

      Like all devices that utilize lithium batteries, the Delphin will lose its charge very slowly while it is off. The Delphin will run for 6 hours of continuous music playback at full volume at a full charge. The screen, WiFi, and Bluetooth take a lot out of the battery. Airplane mode will dramatically increase your battery life.

      Recently, we have learned that charging your Delphin while there is water in the headphone jack will kill the device. Make sure to avoid that :). The good news is that Delphin charges in about an hour. The Delphin will also turn itself off after 30 minutes of inactivity, which is a lifesaver. You can turn off smart shutdown if you want in settings.

      I don’t know how to help the lithium ion battery keep it’s charge better, but there are probably some great resources online that have good advice.

      Thank you!

      Scott

      Thank you for the in-depth explanation, Scott! I will make sure to have the Delphin completely dry before trying to recharge it. Maybe this was also what caused the early demise of my three iPod Shuffles before. I did try to blow air in the headphone jack to get every last of the water out, but maybe that wasn't enough and I just needed to let it airdry longer.

      Lastly, I assume the 6 hours battery life for the Delphin is achieved while it is in the "Airplane Mode". Is that right?

    • scottecwalker1

      I will check on the parameters of the test on Monday, but I think that Bluetooth and WiFi were left on, but were not being used. The screen was also not used except at startup. The screen use and downloading via WiFi take a lot out of the battery.

      Thank you,

      Scott
