For me it was an easy choice cause it's something I use all day every day...I've literally put thousands of hours on mine for the few years I've had them. And even though I'm totally used to them, they still consistently impress me. If I could get away with bringing my Ultrasone circumaurals to work I would, but these are easily the next best thing.
I personally cant stand the kind that literally plug into your ear - they make me feel like I'm underwater. The PK2 manage to sound great and have good bass without forcing you to stuff something inside your inner ear.
