I found the Underwater Audio Delphin 3…
I found the Underwater Audio Delphin 3 unusable for many reasons. I don’t swim with reading glasses or a stylus. If you need reading glasses this will not work for you. The screen is the same size as my Apple Watch. You can adjust the font on the home screen but the in-app font is tiny and unreadable. Next, the in app buttons are so small it requires a stylus. In addition, I was only able to get mine to work once while swimming and in 30 minutes the battery was dead. I didn’t use mine immediately as I was recovering from a total knee replacement. I called to return 32 days after purchase but was told the warranty was only 30 days. The company offered no suggestions to help with app connections or battery life. I bought a headphone /Apple Watch from H2O Audio for swimming and am thrilled.
