Question about Sonos Roam

I only see buttons for volume control and start/stop in the picture. Is there no button on the device itself for next/back (to switch to the next song etc.)? - and no, I don't want to have to use voice control for that). If not, does anyone know of a similar box with such buttons? (I would also like to be able to use it in the bathroom, so using the smartphone to change songs is not an option).
