As before, the Wonderboom 2 is clad in high-performance fabric and gets an IP67 rating, up from the IPX 7 of its predecessor. That means it'll resist dust ingress as well as water (up to depths of one meter for 30 minutes) for showers, pool parties and dusty mountain trails. You'll be able to pick up the Wonderboom 2 up on June 25th for $99.99, in a quartet of color choices: Red, Grey, Black and Blue.
