JBL’s SoundFly speakers are uniquely portable: They don’t run off battery power, but thanks to their plug-right-into-the-wall design, they’re small and light enough to take wherever you’ll have power. Though they lack powerful sound, they sound just fine for casual listening, and their lack of cables and adapters is convenient. If you’ll be listening exclusively to Apple devices—and, more important, you’re typically in range of a Wi-Fi network—spring for the SoundFly Air version, which sounds a bit better; otherwise, you’ll want to go with the SoundFly BT.
