Overview

The Sony CFDS39BK is a traditional boombox that brings together a CD player, cassette tape deck, and digital synthesized AM/FM stereo tuner in a compact, portable chassis. The Mega Bass port speaker design is the standout audio feature, engineered to push deeper bass response than typical boombox speakers of this size. For CD listening, the unit offers 20-track RMS programming to create custom playlists, four disc repeat modes (single track, all tracks, programmed, and shuffle), and an Automatic Music Sensor for quick track-to-track navigation.

The digital synthesized tuner provides accurate, drift-free AM and FM reception with 20 programmable station presets split evenly between bands. A 4-pattern electronic sound mode lets you adjust the audio profile to suit different types of content. The included Remote Commander adds wireless control with a loop playback function. With its carry handle and compact dimensions, the CFDS39BK is designed for use around the house, in a workshop, or anywhere you want simple, reliable audio playback from physical media and broadcast radio.
