The UE Roll’s spherical shape was designed to be used much like a conference speakerphone in that it’s meant to sit flat on its back while the speaker drivers point straight up, which is ideal for distributing sound at all directions - hence the UE Roll’s 360-degree sound capability. The multi-funtion Bluetooth button used on the UE Mini Boom, UE Boom and UE Megaboom to take and make a call is located on the back of the UE Roll and is only meant to be used to pair the speaker with other devices. There isn’t even a dedicated speakerphone button to answer an incoming call because the UE Roll doesn’t have speakerphone and mic support. It’s also worth noting that you cannot use these buttons to pause or skip your music unfortunately. English is set by default, but you can also change the voice prompt language using the UE Roll app for iOS and Android. If you’ve ever used an Ultimate Ears speaker you’ll recognize this pleasing female voice as it has been consistently used across all of the company’s speakers. Pressing both buttons simultaneously will reveal the battery status in which a realistic audible voice prompt will announce the battery percentage remaining. As far as on-board controls go, the UE Roll has two distinct and seamlessly integrated volume controls on the top made to look like oversized plus and minus symbols, which can only be pressed towards the middle similar to the UE Boom and Megaboom.
