SkullCandy are widely known to be awful in both build quality and performance.
If you want lots of bass, then something like the JVC HARX900s, Sennheiser HD280s, Sony MDR-XB700 or Ultrasone (I can't remember their model name exactly, but they're all pretty bass-heavy.)
They have bass, sure, but they have WAY too much of it. It's overpowering, and not tight, clean bass like you want; it's more like: "BOOOM!!!!!!", with little detail for everything else.
Oh, and also: Don't get any Logitech audio equipment if audio quality is important to you. I've found all of their stuff (even the Z-5500s) to be lacking in audio quality, and their bass to be way overpowering and muddy - not good.
In fact, don't get any surround headsets at all... They're all awful in terms of audio quality. A good pair of stereo headphones like the Sennheiser HD555s or ATH-AD700s are much superior for gaming, due to their large soundstage. If you wanted closed back gaming headphones, then the JVC RX900s would be a good choice, and you can add a Zalman Clip-On mic to effectively make them a headset.
