The JBL PartyBox Club 120 has decent controls that will seem familiar if you’ve ever operated another PartyBox-series speaker. There are dedicated dials to adjust the volume and light levels and dials on the back to adjust the levels for the mic/instrument inputs. The dials are responsive and easy to turn, so you can easily switch between settings.

The dials on the front panel feature buttons embedded in the top of the dial. These let you toggle the lights and access various playback features. You can press the ‘Play’ button once to play/pause audio, twice to skip forward, and three times to skip backward. There are also dedicated buttons to toggle through the ‘Bass Boost’ feature, to cycle through different RGB lightshows, and to connect to up to two devices via Bluetooth. Additionally, there are assignable buttons on the top panel that you can use for DJ effects, and a button on the back panel lets you pair another PartyBox speaker for True Wireless Stereo (TWS). A bar above the power button also lets you see how much battery life remains. All in all, the buttons feel responsive and springy thanks to their rubberized finish.
