These speakers come in the form of the SoundLink Revolve and the SoundLink Revolve+. Essentially both speakers are the same, with the Revolve+ (as evidenced in its name alone) being the bigger model. The Revolve measures 6-inches tall while the Revolve+ measures 7.2-inches and has a larger diameter. According to Bose, the larger size of the Revolve+ allows for “higher-volume, more room-filling sound than SoundLink Revolve.”
There is also a difference in battery life where the Revolve can be used for up to 12 hours, while the Revolve+ is good for up to 16 hours, although both speakers can be paired together if you wanted to create a stereo effect. Both speakers are also water resistant with an IPX4 rating. There is also a built-in microphone for speaker calls and can also be used to trigger voice assistants such as Siri or Google Assistant, depending on what phone you’re using.
The speakers are also capable of projecting 360-degree omnidirectional audio and it charges via micro USB. In terms of pricing, as expected to Bose these speakers do not come cheap. The Revolve is priced at $199 while the Revolve+ is priced at $299 and are available for shipping.
