** Update (With Velours On) **
Loving these even more after more time with them. These have now officially taken over as my favorite headphone for gaming. I prefer them to my Samson SR850s due to the weight they add to gun sounds and explosions. It's the perfect mix between my 850s and Beats by Dre Studios when it comes to gaming. The 850s have an amazing clarity and excellent sound stage. However, the somewhat high treble on these cause some of the gun sounds to be a little too weak and high pitched in some games. Despite the hate for the Beats on these forums, I actually found them pretty good for single player gaming. They add the impact of explosions and gunfire better than any headphones I've tried. What hurts them is you lose some of the detail during intense moments in game due to the emphasized bass. For example, during intense fire fights you may not hear your bullet casings hitting the ground, or hear what your fellow soldiers are yelling, or hear every detail of your gun reloading. Call me crazy, but this adds to the immersion in games for me.
What the HTF600s do is give me all of the clarity and detail in the game, while adding just enough weight to gun fire, and sub bass to explosions. They also have a suprisingly good sound stage. Not too hollow, not too cramped. Just a great mix in my opinion.
As for music, it doesn't get much better. Simply put, they give me a $150+ balanced sound with excellent bass.
Still haven't tried movies because I'm too busy playing Gears of War 3 and Battlefield 3 Beta (PC). Will definitely chime in once I've tested them.
I HIGHLY recommend these budget cans if you're looking to spend $200 or less on a great all around headphone!
