Deep. Loud. And immersive, too. SoundLink Revolve II is a portable wireless speaker from Bose that’s engineered to deliver true 360° sound for consistent, uniform coverage. Place it in the center of the room to give everyone the same experience. Or set it near a wall and sound will radiate and reflect around the room, immersing you in that same feeling you felt at your favorite show. The tapered cylindrical shape makes this Bluetooth speaker easy to grab and go. Its durable aluminum body provides worry-free protection, and its water- and dust-resistant design (IP55 rating) lets you keep the party going, even if it gets splashed by the pool. The rechargeable, lithium-ion battery plays up to 13 hours — for full-day listening. Voice prompts talk you through wireless Bluetooth pairing, and you can easily take calls with the built-in speakerphone. You can even access your device’s default voice assistant right from your speaker. Connect the speaker to an Amazon Alexa-enabled device, like the Echo Dot, for even more control. Pair two SoundLink Revolve speakers in Party Mode for more performance. Try Stereo Mode where instruments and vocals will naturally separate and spread across an immersive soundstage — making your music sound and feel as you know it should. Bose SimpleSync technology lets you pair the Bluetooth speaker with a member of the Bose Smart Family to play in sync. The Bose Connect app helps you manage your devices, unlock features, and access future updates. You can easily charge the speaker via Micro-B USB port. And the auxiliary input allows you to connect to other audio sources. This mobile speaker is available in Triple Black or Luxe Silver. Included: SoundLink Revolve II Bluetooth speaker; USB cable; wall charger.
