SONY CD player pursuing high sound quality - Model: CDP-337ESD - Power: 100V 22W 50/60Hz - Output terminals: Line output (fixed/variable) and digital output - Output selector: Equipped with an output selector Headphone output is good with no skipping or noise. Line output was confirmed to produce sound by connecting it to the video audio input terminal of a TV, as I do not own an amplifier or speakers. I cannot judge the sound quality. The CD tray requires manual operation after pressing the open/close button. A headphone-to-earphone conversion jack is also included. No instruction manual or remote control. Please understand that this is an old item. Thank you for viewing.
