Rebuilt from the ground up. We cranked up the bass, fine-tuned the mids and highs for a crystal-clear experience, and built a battery that lasts a huge 20% longer. While we were at it, we even came up with a signature mechanism that lets you effortlessly pop off the front grill. Why, you ask? So you can customize the look of your speaker. Still the most powerful portable speaker in the game. And now, it's better than ever.
