Sound quality is enhanced by Sony's digital Mega Bass sound system, which uses digital processing technology to produce deep bass tones with low harmonic distortion. A digital control allows you to make precise adjustments to volume with a push button located on the front of the unit, while the volume level appears on the LCD display. The D-E206CK's five playback modes include repeat and shuffle, as well as a two-position automatic volume limiter to minimize distortion.

This player has a heat-resistant body to protect against temperature build-up inside your car in hot climates. Sony boasts up to 15 hours of playback with two AA batteries when the antishock protection is off. This player comes with a one-year warranty on parts and a 90-day warranty on labor.
