The JBL Soundfly is a fresh take on the small speaker craze. Instead of relying on a battery for power, the Soundfly sports an electrical plug on the backside. Just plug it into the wall for power and connect your iOS device with Airplay. There are no wires, once it’s connected to the local wireless network, it always works. The obvious downside is that the speaker can only be used where there’s a plug. But, with the right location, I found the Soundfly to be a dead-simple solution to an age-old problem of blasting Ke$ha while you’re taking a shower.
