OK my pair arrived today :)
So far I love how they look and how well made they are. Unfortunately they are very slippery and loose on my head (they slide off if I bend down to tie my shoes). This issue is also affecting how they sound. My initial impression was wow are these ever bass anemic, thin sounding and brittle! If I press in the pads the sound improves substantially but this is not an ideal solution and there does not appear to be any way to tighten their grip. What's weird is I have also owned the K550 and had no issues getting a good seal. As these stand right now I think the K550 and SRH-940 are substantially better sound wise. I have plugged these in to cook over night to see if they change sonically and I am going to see if I can tighten their grip. Hopefully they improve. Otherwise these may have a very short life in my home.
