They are heaven for your ears. Went from Hifiman HE 500s to these and what can I say. There are almost no trade offs with the HD 600. You get everything, great mids, highs and a good low end that is not sloppy in any way. They are extremely light which makes them very, very comfortable. Comfort is huge for me, as the HE 500s made my neck sore to the point where I didn't want to use them for fear of the pain coming back. I am using the HD 600 with a Schitt Jotunheim amp/dac and the combo has been excellent. The HD 600 will always be in my possession.
