there you go, there is a deal, and vibrant by far is the header for the cobalt, nothing compares to its quality...NOTHING!

not CTI, not CIA, not hahn, not pacesetter, not CA v1 or v2, no OBX midlenght, not OBX shorty, nothing compares to vibrant quality and show all in one, and for the cost that kills the competition

the vibrant is also, by far, sounds the absolute worst. But i'll agree, hands down the best quality piece out there for the cobalt, especially for the money.
