Hi Gunnar,
I got a set of Whites headphones with one of the MDs I purchased second hand off EBay. They sound muffled, kind of like listening through a door to a conversation. I just couldn't hear what was going on.
I got the basic Killer Bs with only one volume control. Even the basic set has a wonderful clear response. It only cost $72. No tax & No shipping. It cost more than that for a set of Radio Shack"s cheapest wireless headphones, and you get so much more. I know because I wasted my money on a set.
They make them with a 9' coiled cord. It is the best cord I've used, period. It is just the right length so that you hunt without it being in the way, and it is still long enough that you can set it down and have plenty of slack to move around and dig your target without pulling on your headphones.
They have high quality construction and a limited life time warranty. I don't know why I waited so long to get a pair. It's one of the best investments I've made.
Mary Christmas and happy New Year,
