Reading research clearly indicates that students develop literacy skills much more quickly in an audio-rich environment. The high-quality audio of our learning centers helps develop students' listening skills whether they are learning phonemes or practicing a new language. In addition to the Spirit multimedia (AM-FM/CD/Cassette) player are six switchable stereo/mono headphones featuring ambient noise-reducing earcups with padded headband; and ten-position stereo jackbox with individual volume controls for individual sound customization during group use.
