Just wondering if anybody owns or has tried the Zalman 5.1 Theatre Surround Sound Headphones. I'm thinking of ordering a pair with the Zalman headphone amplifier. Also, do the headphones sound better through the amplifier, or when hooked up via a PC soundcard. Are they produced well and is sound good for video games and DVD's. I'm looking for feedback from somebody that has tried them, not a review off some site trying to sell them. Thanx heaps guys.
