VOX (Voice) Books are the world's first audio books that live in print books. The permanently attached VOX Reader transforms an ordinary print book into an all-in-one read-along. There's no need for computers, tablets, or CDs. Children simply push a button to listen and read. Like a Playaway device, there are buttons to push to turn the device on, play, skip forwards or backwards a track, adjust the volume, etc. There is also an earphone jack for private listening. All books will be charged prior to checkout. Earbuds are not included.
