I upgraded these from the original WSH. I much prefer the newer model:
No more creaking with any minuscule head movement
Slightly heavier, which feels better in terms of build quality of the original without feeling heavier on your head, top foam also feels of better quality
Able to use via 3.5mm cable to use on portable devices and anything else with that jack.
Sound quality is better
Smaller USB Dongle
Though I will say, those with ginormous heads like mine, the originals fit better. These still fit and are fine, but barely. The original still had room to spare in adjustments, while this I have to adjust all the way to fit. Though I'm in the small minority with my large head.
