Portable Powerhouse!

You can go from unboxing to jamming in seconds with almost no setup required! The sound is incredibly well-balanced without any distortion at high volumes. The guitar input and battery-saver features are fantastic additions you don't usually find on other models.

Great sound quality and good Bass, cool design

Picked this up during the summer and it has been a total game changer for our pool days. The audio is crisp, the bass hits just right, and the battery life is seriously impressive. It’s survived countless hangouts with friends and family without breaking a beat.
