The JBL PartyBox 100 has sub-par controls. You can play/pause your music, turn the volume up or down, turn the power on/off, control the Bass Boost and Mic Echo settings, control the RGB lights, and activate Bluetooth pairing mode. The Bass Boost has three different settings: Off, Level 1, or Level 2. You can even adjust the volume for the mic and guitar inputs. The LED lights also indicate the battery level for a few seconds after you turn the speaker on or when you click the buttons. The buttons feel solid and clicky, but they don’t always register the command immediately after you press it, which can be frustrating.
