When I was at Walmart. I saw the skullcandy crushers. the price was $100.00 When I test the music with bass on it, I touch the earcups while the music is playing and it vibrates because of the bass driver of the headphones. The skullcandy headphones has two drivers. One is the regular driver and another one is the subwoofer. Putting the Skullcandy crushers around a cup of water and you put the bass music, it vibrates and water in the cup ripples. I don't know if the Razer tiamat 7.1 or any type of Surround headset and Razer hammerhead that vibrates like skullcandy crushers. Anybody have surround headphones with subwoofers, if you ever put a bass music, Did the Razer surround headphones and hammerheads vibrate?
