^ That looks awesome, like something the Ghostbusters would use to detect traces of ectoplasm.
I'm not an audiophile or anything, I just like geek / gadget talk, but I splashed out on my first ever properly great pair of headphones, Sennheiser HD25-1 IIs and I really LOVE them. They add a really bassy punch to music when needed (Siamese Dream sounded like being at the cinema with a really good sound system) but are clear enough to retain lots of nice details. They're portable so I can get more use out of them than I would from a pair of home listening headphones (I'm too hyperactive for that and I don't like open type headphones anyway). They make you look like a DJ with them around your neck and a cyberman when you're wearing them, which I've had to decide is a good thing.
I mainly use them straight out of an iPhone though.
