A:Answer The Revolve+ is the slightly-larger higher end model with 16 hours of battery life and louder, deeper sound, and the Revolve is the slightly smaller "lower end" (less-higher-end) model with 12 hours of battery life and slightly less loud sound. Both sound similar, both are water resistant. They are very similar speakers, but the Revolve+ is just a step better than the Revolve, in most aspects. Oh, and the Revolve+ has a handle for carrying.
