Ultimate Ears is known to collaborate with artists to create custom designs for their UE BOOM mobile speakers. This time they worked with contemporary graffiti artist Greg "Craola" Simkins. Craola is usually inspired by his favorite childhood books and cartoons, pop culture, nature, and "carnival kitsch." It's evident in the whimsical feel of the Safe Haven Edition UE BOOM. 

If this catches your eye, you better work fast. There will only be 200 pieces of the Safe Haven Edition UE Boom. This will retail for US$199.99.
