Underwater Audio's Guide To Tidal

This guide is for Delphin users.

Things you will need to follow this guide:

  • A strong WiFi connection
  • A Delphin Micro Tablet
  • A paid subscription to a Tidal account that allows offline listening: Either the $9.99/mo Individual, or one of the HiFi, Family, or Student accounts will work. A free membership will not be able to play offline while swimming. This link will take you to Tidal’s website for learning more about the different subscription tiers.


Big hint! If you are already past the initial Delphin set-up process: To make setting up and installing anything on your Delphin easier, from the front screen, swipe up for more options. Go to Settings > Display > Sleep and choose a longer time, like 10 minutes, to keep the screen from going dark too quickly. Just remember after you have finished setting up to go back and turn the screen down to a lower time. The two fastest ways to drain the battery on your Delphin are keeping the display screen on and being connected to WiFi. Keep the screen off whenever it is not in use and turn off the WiFi any time you are not actively using it to keep your battery running for the longest time.

Some important notes before we start:

Tidal also has a help page and information. This link will take you to Tidal’s Support page for if you need any other help, such as resetting your password, login details, accounts, or troubleshooting.

WiFi is required:

While making any changes to your playlists or while downloading your music, you must be connected to a strong WiFi connection. We recommend being as physically close to your WiFi router as possible. Due to the efficiency of the waterproofing on a Delphin, it does have a shorter WiFi range than other comparable electronic devices.

At least once a month, you will need to reconnect your Delphin to the internet to allow Tidal to verify that your account is active. This will still matter even if you use your Tidal account on your phone or computer. The Delphin Player has to be reconnected once a month to the internet so that any paid subscription apps (Audible, Pandora, etc.) can verify for billing purposes.

While swimming, you will want your WiFi turned off. Water and WiFi do not mix, so even if the pool you swim at offers free WiFi to guests, your Delphin will not be able to work while in the water. The easiest way to do this is to go to Settings > Network > and check the Airplane Mode box. (When you need to reconnect your Delphin to the internet, these are the same steps, just make sure the box is NOT checked.)

To start you will need a Tidal account. If you do not have one already, we recommend setting up an account on either your Computer or Phone to have an easier time with your keyboard and screen size. (You are not required to connect your Delphin to your phone, that is optional!)

Download Tidal onto your Delphin

If you have already set-up your Delphin and want to add a new app:

Open the ‘Help’ app which came preinstalled on your Delphin. Scroll until you see ‘Install Apps’ and click on it. Open the Amazon Appstore and search for Tidal. Click on the app and download it.


Are you going to be using Tidal frequently? We recommend making it one of your Favorite Apps so it will be on the front screen of your Delphin. On your front screen, decide which of the four apps you would like to replace with Tidal. Press and Hold that app for a few seconds until a screen pops up showing all of your apps. Scroll down until you see Tidal and select it. This will make Tidal appear on your front screen.

Sign into Tidal on your Delphin

Open the Tidal app.

This process is very similar to signing into any account, just type your username and password when prompted.

If you would like to use remote connect in order to utilize your smartphone to aid in app setup, click on this link to learn more about it.

Here is a video on YouTube explaining how Delphin’s remote connect works.

Once you are in the app you may download playlists, or use any of the other features of the Tidal app.

Download offline playlists for the pool

Before you head to the pool, you will need to get your apps ready for offline use. Remember, WiFi doesn't work in the water.

After opening Tidal, you should see the 'My Collection' section.

To download a playlist you have already created, scroll down the playlists and select the playlist you want to open it. When the playlist is open, there should be a picture with four album art covers. Scroll down the screen from there and you will see the option to 'Download' with a small gray circle across from it, tap it and the download will begin.

After your download is complete, we need to verify that your offline playlist is working properly. To be sure that our playlist is working without the internet, you'll need to turn off your Delphin's WiFi. To do this, hit the back arrow button on the side of your Delphin until you have returned to the home screen. Go to Settings > Network > Airplane Mode. This will toggle your WiFi off. To enable WiFi, follow the same steps above.

Now it's time to check to see if our playlist is working. Go back to the Delphin's home screen and select Tidal from your home screen apps, or by swiping up on the arrow and scrolling until you find Tidal. Within Tidal, find your playlist and try to play it. If it works, you have successfully downloaded your playlist. To add more playlists, simply turn off Airplane mode and repeat.

You can also download albums and pre-made mixes that Tidal creates in the same manner. Just go to the mix or album of your choosing and hit the download button!

Remove playlists from your Delphin

Do you want to swap out an old playlist for a new one?

On your Delphin, open Tidal. You should see a menu on the bottom of the main screen. Go to 'My Collection' and choose ‘Playlists’. Find the playlist you would like to remove and tap on the small green circle across from 'Download'. Tidal will then ask you to check if you want to remove the download.

If you select ‘Delete Playlist’ this will delete the playlist from your entire account, not just the Delphin.

Other tips & considerations

Your Delphin runs a full version of the Tidal app. As long as it is connected to WiFi you can use all of the same features as your phone or computer... but due to the screen and keyboard size, you might have an easier time setting up playlists on a larger device then simply following the steps above to download them to your Delphin for offline listening.

If you're determined to build playlists directly on your Delphin, here's some helpful info:

To create playlists: Using the Magnifying glass button, you can search for a song or artist you would like to listen to. You may also search for genres or browse ‘moods’. You can use the three-dot menu () next to anything and download music and other playlists you would like to listen to.

If you are on your computer or phone and create playlists, save music, or change anything else you will need to download it onto your Delphin by reconnecting to WiFi and following the steps above or it will not be there the next time you swim or go offline.

Does your music seem to be missing?

We have been told that Tidal will remove your downloaded music if you go beyond 30 days without going online, but we have not seen this issue yet on the Delphin. Usually the app will just stop working altogether but will begin working again once you go online. If your downloads do appear to be missing, simply reconnect the Delphin to WiFi and download your playlists again.

Do you have a completely unknown issue not fixed by anything above?

The first thing Tidal and Underwater Audio will recommend is uninstalling and reinstalling the app. Since it is a paid subscription app, you will not lose all your music. Uninstalling the app will remove your downloaded music. You will simply have to sign in again once it is reinstalled. You will also need to re-download your playlists while connected to WiFi before you will be able to swim with them again offline.

To uninstall an app: Go to Settings > Uninstall Applications > Tidal > OK

We very much recommend rebooting the Delphin between uninstalling and reinstalling an app. Just power off the Delphin and power it back on again.

To reinstall Tidal: Go to Help > Install Apps > Amazon Appstore. Search: Tidal > Download
