The Pioneer HC-CA0502 is a 1.6m straight headphone cable designed especially for the HDJ-X10 headphones and allows you to replace an old or damaged cable so you can continue to enjoy your X10 headphones without needing to get a whole new pair. There is an L-type angled mini-Jack connector at one end and a mini-XLR connection at the other for connecting to the headphones so you can quickly detach the cable when on the road. An independent ground wire inside of the 4-core twisted-structure cable works to give you superior left and right channel separation which improves the overall sound quality.
