This speaker has excellent controls. The simple button layout is intuitive and user-friendly, with some buttons that have multiple functions. There's a power button, buttons for adjusting the volume, a multi-function button, and a Bluetooth button (which glows when a device is connected). The buttons are tactile and responsive, and there's even voice assistant functionality through your smartphone. You can hold the multi-function button to activate your smartphone's voice assistant, and you can also use it to switch between two calls, turn off speakerphone, and transfer the call to the phone it was connected to.
There are also clear voice prompts that indicate that you're pairing with the speaker via Bluetooth and which device you're connected to, as well as when the auto-off function is enabled or disabled. It tells you the battery level when the speaker's turned on, but you can also hold the power button for this information. Additionally, there are visual indicators for when the speaker is connected via Bluetooth or the AUX input, as well as for the battery level. Unfortunately, there's no audible feedback for lowering or raising the volume.
