NVXes should be pretty damn good for their price. Having fairly neutral sound signature (I have HM5, but sonically they should be the same) they don't have outstanding bass (not lacking, just balanced) straight out of the box, but they respond to equalization well.
Read about them here:
They are currently at close out prices--while they last.
Whoever told you the NVXs weren't for extended use is wrong, because they're by far the most comfortable cans on your list. Their sound signature is not meant for your genre of music though. I recommend Sennheiser HD518 or the Sennheiser HD280 Pro. The 518s are semi-open so they leak a bit of sound. They sound great and have been on sale recently for as low as $65. Go for the 280s if you need closed headphones but the 518s are generally better for home use.
I find them to be very comfortable, but of course headphone comfort is a very individual thing.
