This is a CD-ROM drive made by Plextor. It has a headphone jack and volume control. Model: PX-45CH. This drive is for caddy cases only, so the tray does not come out. You insert the disc directly. I have only confirmed that it powers on and the lamp lights up. This is an as-is item. Please consider it as junk. There is some discoloration. It shows signs of use. - Brand: Plextor - Model: CD-ROM Drive - Features: Headphone jack, volume control dial - Condition: Power lamp lights up Thank you for looking.
