It is nearly new, i've got se425 and so that i want to sell it. There are no case but it has shure foams and silicons with it.
There are no difference between se315 and it except removable cable. it has detailed mid-based sound and very clear high response with enough base. It sounds perfect with Jazz, i open base when i listen rock-based music and it sounds perfect again. Also i used it in the live-monitoring. It is definetly better than se425 in the live-monitoring. I think it has very detailed-mid response so that it is better than se425
