The Fidelio SoundRing Portable Speaker with AirPlay from Philips lets you stream music from your computer, iPad, iPod, or iPhone. It has a rechargeable battery that can provide up to three hours of playback using AirPlay or up to 6 hours when using the aux-in or USB ports. It can be used simultaneously with other AirPlay speakers in your home. The Fidelio delivers 16W RMS total power output through four speakers – two front-firing and two side-firing – and a built-in bass sound pipe that combine to “create an immersive, natural listening experience that you can enjoy from anywhere in the room.” It’s small enough to be portable, and it can charge your iPhone, iPad, or iPod through its USB connector. The Philips Fidelio SoundRing Portable Speaker is $299.99.
