Read more… 360° Sound The Revolve is built for portability, but don't let the size fool you, it delivers awesome audio. A highly efficient transducer produces top-notch sound across the full frequency range. Dual-passive radiators handle the deep lows and make sure bass is powerful, warm and vibration-free, while the acoustic deflector guarantees omnidirectional listening. Packed with Bose® tech, it commands a rich, detailed, lifelike sound in all directions. Stylish, Robust, Water-resistant The first thing that strikes you about the Revolve is its looks. The speaker grille doesn't even have a seam for true consistency of sound and chic. But this is a tough speaker. It's IPX4 rated water-resistant so it'll happily handle getting caught in a shower in the park, or life by the pool or beach. It's even equipped with soft 'bumpers' top and bottom to allow for slightly rougher handling, like quickly tossing it into your bag. And smooth, soft buttons provide natural, intuitive interaction. Brilliant Bluetooth, Big Battery Connect your smart device wirelessly by Bluetooth to seamlessly play your top tracks, 360° style. The Revolve can connect to two devices at once and automatically remembers the last eight for quicker pairing. NFC devices link up with simple one-touch connection. Recharging via USB, its battery lasts up to 12 hours so it'll easily keep going all day, wherever you take it. Phone Functions It works as a speakerphone when your phone's connected so you can take hands-free calls with ease, and the quality of the Bose® speakers means words are clear and less muffled. And the multi-function button even allows voice interaction directly with Siri and Google Now.
