5 noises: white noise, trickling stream, crickets, heartbeat and hairdryer. Had white noise playing all night, worked beautifully. The 5 musical features are Lullaby, Rockabye baby, twinkle twinkle, fleur de lis and another classical one (I can't pick it) good size and very handy being able to charge it on the wall. Does not come with wall plug but any USB plug seems to work well. Love that it is portable, monkey is cute and not too big. Even has a velcro strap to anchor it to the cot rails.
