Meet the JBL SoundFly Air AirPlay plug-in speaker ($200). It plugs directly into your wall outlet. All you need is an Apple AirPlay-enabled audio device, such as an iPhone, iPad or iPod touch, and a home Wi-Fi connection.
This small wonder delivers a full spectrum of sound. A free, downloadable app gives you additional functionality so you can browse music with cover art, adjust volume and tone, and fully customize the digital signal processing (DSP) to get the best sound wherever you plug it in.
The SoundFly Air speaker features 20 watts of power amplification and frequency response up to 20kHz.
