I received these about 10 years ago and used them until a few years ago, but I haven't used them recently, so I'm putting them up for sale. I've confirmed that all three units power on, but I don't have any audio cables, so I haven't been able to test the sound output. One of the CDJ-350s seems to have a CD inside, but I can't eject it. They will be sold as is. Considering these points, I'm selling them as junk items.
