Headphones, any suggestions?

[Caprice]

I really enjoying listening to audio through good headphones now. Before I didn't really care but man, it feels soo good on my ears.
I recently bought a pair of Sony MDR V-500 headphones for when I work in my studio. They can take a lot of input without distortion through the mixing board and the bass is very nice but as for using with my ipod or even my record player they are lacking, they're just not loud enough to use for "personal" headphones.

I was looking at the new headphones by Matix, the domepiece. Their specs are pretty solid but I always study a lot before i commit to buy anything.

I'd like input though for a good pair of "personal" headphones for under $100. Thanks,
