One plus that was not mentioned (and serves to counter the 'con' of the jack design) is that these work with the goofy iPhone jack. Why Apple went with the recessed headphone jack is a mystery to me. It is hard to find headphones that work with the iPhone without using an adapter, but the Vmoda headphones work nicely and sound incredible.
If you have an iPhone (and perhaps even the new iPod Touch... not sure if it has the same style jack) then these will give you much richer sound than the standard Apple headphones.
