The Sony DE-451 compact portable CD player offers 40-second ESP2 SteadySound to keep your music skip- and jitter-free. Its lid helps protect against high-temperature buildup, especially when using the Discman in hot climates or in a car. It also features a Mega Bass Sound System with a groove sound position for deeper, richer bass tones and more pleasing overall sound.
Other features include 10 playback modes, 22-track RMS programming, resume play, and a two-position automatic volume limiter system. This player also offers up to 16 hours of playback with two AA batteries (ESP off), which is made possible by an advanced design that allows extended battery life. This player comes equipped with stereo headphones.
