I want a pair of relatively casual-use headphones for use indoors. The problem with my main headphone right now is that it comes with a hulking amp which means that it is pretty much fixed in place. I'm finding that I want to listen with say a laptop on a couch, and it's irritating sometimes listening using my earphones or my closed phones. I'm looking for something which would sound pretty good with a laptop headphone jack upwards, so not looking for a headphone with a gazillion-ohm impedance. I'd like something I can throw around with relative impunity and withstand the occasional accidental sitting-on, ~1.5m stretching curly cable if possible and a circumaural (around ear), comfortable, open design. I was thinking of acquainting myself with the Sennheiser HD595. What say you?
