Impress your friends wherever you go with the POW Audio Una X Expandable Portable Speaker. This expanding speaker is like a boombox—but better. It provides omnidirectional, 360-degree output and delivers impressive bass along with super clear notes. With 16 hours of playtime, the Una X will never let the party die out. Designed with a WaveBloom audio expansion chamber, this portable boombox grows to a larger size. That’s perfect for when you just need more volume. Stuff it in your backpack when you’re headed out or when you’re done listening to music—as if that ever happens. Compatible with Bluetooth, this wireless gadget can sync with another one to create left and right channels.
