"World's 1st Waterproof Curved Touch pad MP3 Player", that's what the company is calling its new underwater MP3 player. The NU Dolphin Touch has an attractive cylindrical design with touch sensitive controls on it. It is IPX7 certified to be waterproof under water. This means you can actually listen to music underwater while swimming, surfing or while simply walking in the rain. The player supports MP3 and WMA format and has 4 GB of internal memory to save your music files. It also has a built-in FM radio, which is also said to work underwater! We took one for a dive to see how it performs in these tough conditions.
