Thanko released a totally waterproof MP3 player “Waterproof MP3 Player LITE 4GB”. You can listen to music under water with this product and it’s perfect for using while you surf, swim in the pool, ski, etc.
The earphone jack is not a plug-in type but screw-in type, so it doesn’t allow water to enter the main body. 2 kinds of ear pieces come with the product: regular ones for a regular life and ones for underwater that have 3 small plugs lined on each side.
Price: 7,980 yen (including tax)
