SoundLink Revolve+ II, the best-performing portable Bluetooth speaker from Bose, is engineered to spread deep, jaw-dropping sound in every direction. 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 with a flexible handle makes this wireless speaker easy to grab and go, while a durable aluminum body provides worry-free protection. And it~s water and dust resistant so you can keep the party going, even if it starts to rain. The rechargeable, lithium-ion battery plays up to 17 hours ~ for full-day listening. Voice prompts talk you through Bluetooth pairing, and there~s a built-in speakerphone for calls. Use the Bose Connect app to pair two SoundLink speakers for Stereo or Party Mode. The app also helps you manage your devices, unlock features, and access future updates. Available in Triple Black or Luxe Silver.
