OK, got mine from Linsoul just one day apart from the Dekoni nuggets from Drop (which is a great thing).
As I was very aware already, I had to bend the heck out of the piece of metal they call headband. It actually does not look like a machine bent that piece of metal anyway, since it is off center.
After almost flattening the top I was able to bend the edges where the yokes attach to a decent angle, enough that the bottom part of the earcup seals around the bottom of my ear.
Again due to large head, I have the yokes all the way to their limit, so I cannot fit the original headband padding, otherwise they just don't reach, so I had to remove the padding and put 2 Dekoni nuggets in its place.
Now for the sound:
It works OK with low-powered equipment, like a phone or a computer, but these guys need power to shine. When I connected them to my Dark Voice (with a Sovtek pre-amp tube and a Winged-C power tube, with much more low end than the original tubes) the sound stage opened up a lot more, and I was rewarded the more power I gave it.
I also tested it on my Schiit Magnius, but only through the single-ended connection, which is not the most powerful, but it sounded great. I will get one more Hart Audio cable adapter so that I can connect it to the XLR connection for good measure.
At any rate, the sound signature reminds me a lot of the HD-6xx, which I auditioned side-by-side, where the low end is definitely rolled off, but the treble is also rolled off at the top and that helps protect from potential sibilant "S" and "SH" that I am not a fan of.
If you like harder-hitting low bass I don't think this is for you.....I prefer the sound of my Planar headphones like the HifiMan Deva or the Monoprice M1060C (modded open), specifically for the faster deeper low end, but I find these very interesting for the price.
Now to look for better pads and maybe a more professionally made headband, or adapt one, since the limitation of the rotation of the support is very challenging!
