Spiffy. I guess I can see you as an on-ears-closed kinda hoopy frood. I like the detachable cord design in those - imagine it helps with storage and longevity.
It took me several years to convince myself that a DAC was more than smoke and mirrors, but I confess it does reduce some of the hum from onboard audio and more importantly I dig having an actual analog volume nob dedicated to the headphones.
