I've been playing through Guitar Rig 4, just plugging my guitar into my Fast Track Pro and doing it that way until I can use my SM57. However, anytime I play with anything more than mid-gain, it sounds terrible. I'm thinking this is more to do with the earphones I've been monitoring with using a 3.5mm -> 6.5mm adapter than anything else, so I'm looking for a decent, cheap set of headphones for home recording use. I've heard good things about AKG and Sennheiser, however some of their products are very expensive.

I came across these AKG K44 headphones, are they any good, or should I save up a bit more? If so, what would you recommend? I'd love to stay under about $70AUD if possible.
