Pioneer CDJ-850, compatible with MP3/WAV, equipped with a USB terminal, and a backlit LCD display. - Model: CDJ-850 - Brand: Pioneer - Features: MP3/WAV compatible - Connectivity: USB terminal - Display: Backlit LCD - Color: Silver - Operation Buttons: Loop, Effect, Track Search buttons - Size: Compact design Thank you for viewing. While it appears to be in relatively good condition for its age, the rubber part of the platter is slightly sticky due to hydrolysis. Also, USB reading works without issue, but CDs are ejected without being read when inserted. *This is likely due to a malfunction of the pickup lens.* Due to the above, I am listing this as a junk item at half the market price on Mercari. Although CD playback is not possible, USB operation works without problems, making it ideal for practice. Thank you for your consideration.
