With this Bose SoundLink Revolve+ II Duo Pack, you can enjoy stereo sound or a higher volume at a party. You can easily link the speakers to each other via the Bose Connect app and start streaming. The Revolve+ II is a little larger and heavier than the SoundLink II, which provides a more powerful sound reproduction. This speaker has a built-in handle, so it's easy to transport it. At home, you can place the speaker in the middle of the table. Thanks to its 360-degree design, it distributes the music throughout the entire room. And because it's dustproof and waterproof, you can take the speaker outside. It won't break when it comes in contact with water.
