I have had both brands and both are top of the line. Both are durable and have great audio. The thing that sets Killer B's apart from Detector Pro is the ear cups. Killer B's are available with leather ear cups, which in my humble opinion are more comfortable. But, with the comfort, comes an issue of how long the cups last. Leather will eventually crack and need replaced. I hunt every day, weather permitting and have my phones on at least 25 to 35 hours a week and leather is just plain more comfortable. R.L.
