There's a source button to switch between Bluetooth, AUX-IN, and FM Radio, and the speaker emits audible feedback to inform you when you switch sources.

You can press the light button to turn its LED lights on and control its brightness level. There's a large volume knob you press when you want to set the speaker to standby mode, which causes the power light to turn green. The Monster Rockin' Roller 270X has a wide selection of well-identified, easy-to-use controls. On top of the speaker, there's an anti-skid Qi wireless charging pad you can use to charge your Qi-compatible devices like your smartphone or earbud case. This speaker also comes with an external microphone that's mainly made of plastic, though it doesn't feel very premium. Its inputs are protected by small flaps, and there are two velcro strips on its rear to attach the included accessory bag to the speaker. It's rated IPX4 for water resistance, meaning it's certified to withstand small splashes of water, so you don't have to worry about it getting a bit wet outdoors. There's even a bottle opener built into its rear so you can enjoy drinks with friends. There's a foldable carrying handle to help you carry the speaker, and there's also a separate telescopic handle and wheels built into the speaker to help you wheel it to your next party. It's mostly made of robust-feeling plastic, and there are metal grilles on the front and sides of the speaker.

The Monster 270X has decent build quality.
