A Sony Walkman with all the features. This little unit records onto blank cassette using an external microphone (supplied - see photos) which comes with a tie clip and a desk stand. It replays cassettes using auto-reverse (you don't need to change the tape over when the first side finishes). It has optional Dolby noise reduction (most commercially recorded cassettes were encoded in this format). It has a three position 'bass boost' for cassette or radio replay. There is an AM/FM radio with 5 user adjustable presets. It has a belt clip which can be removed, and it comes with a soft carry pouch. It needs 2 AA batteries (not supplied) and wired headphones with a stereo mini jack (not supplied).
