I purchased this about six months ago and used it once, but it was more difficult than I expected, so I'm selling it. Contents: - DDJ-FLX4 main unit - Starter book - Headphones - Speakers - 4 cords - Type-C cord According to the website where I bought it, you can use this to DJ with a computer. Plus, there's an extra Type-C cord, so you can also DJ with a smartphone. These are the 9 items in total. The box is not included, and it will be shipped in a Mercari delivery box. Please understand that this is stored by a private individual. The DDJ-FLX4 is a simple and user-friendly 2-channel DJ controller with multi-app compatibility, perfect for those who want to start enjoying DJing.
