These cables caused sparks in my powered speaker and destroyed it, luckily I had full coverage for them but I would never buy them again and would not recommend this brand , if you are I was wondering that other connected cables were the same for both speakers. Same power cords had no problem before I tried them and when plugged in and turned on sparks started, I looked at their other XLR cords and other customers had the same problems with these proprietary cords, really sucks because I used to was a fan, AVOID AT ALL COSTS!
