This is my first review and it's going to be brief...Never in my life have I been so damn impressed with an audio product (I have a bunch) than I am with my Custom K10's!!! There is not 1 thing that I can think of that hasn't completely surpassed my expectations...I'm a picky son of a gun and these have surprised the hell out of me and I had my bar set extremely high...Do yourself a favor...run don't walk to Nobleaudio.com and get ya some
