This connector serves its purpose very well and is very inexpensive. Unfortunately you have to solder the back so that you can actually use it. I've soldered it to another cheap midi cable I had lying around, and use it in my band's rack. It's a great alternative to the more expensive MIDI connector that doesn't require any soldering, and serves the same purpose. If you are ok soldering, give it a try and save some eurs.
You can either solder the 5 wires, or just 3, since MIDI in general doesn't require them all (depending on the interface you will be connecting to).
