Corsair 1500's? Did you research the cracking problems? I would treat them with kid gloves, don't take them off by hold the ear cups, only hold them from above the swivel joint on the main band, otherwise it is only a matter of time before they break. I have the 1300's which replaced my broken HS1A's which broke in the way. If anything the Vengeance series are even worse. I am being very careful with these.
