Playaway is a solid-state prerecorded audio player introduced in 2005 and redesigned in 2016. About the size of a deck of playing cards and weighing 2 ounces (57 g), it can store up to 80 hours of audio. As of March 2010, the
audiobooks are all produced in high-definition audio. The digital content (audiobook or music compilation) is preloaded at the factory and cannot easily be changed or copied by the end user. A 3.5 mm stereo jack provides output to earphones or an external amplifier. Playaway Light was explicitly designed to use the most commonly available cassette adaptors and FM transmitters. Power is provided by a changeable 1.5V
AAA cell, which the manufacturer claims allows it to operate approximately 20 hours before battery depletion, 30 hours for the newer versions. There are about 15,000 titles on Playaway, generally priced in line with the publisher's suggested library pricing for the CD equivalent. As of 2013, the newest Playaway versions feature HD Audio and high-definition sound. These new units enable users to lock the keypad and slow down reading speed. In 2016, Playaway added a backlit LCD screen with more details and simplified the button layout. == Wonderbook ==
