I have a pair. They're really cool, but I haven't found a use case for them. They're open-back, so I can't use them when I'm working in public spaces. They require their own USB DAC/AMP, so I can't use them in my analog chain at either my desktop or home theater. And the DAC/AMP requires too much power to use them with my phone, so I can't use them while walking around. The only time I use them is when I'm working from home and for some reason I want to use my laptop in bed or in the living room instead of my desktop, which is rare.
