I have tried them. I reviewed them well over three years ago:
Philips SHP9500 / SHP9500S Headphones Review: A Great Cheap Open Pair!
I’ve wanted to check out the $70 or so open-backed Philips SHP9500 headphones ever since THIS infamous Z Reviews video.
I wasn’t as big a fan of them as some folks are. The pads are shallower than they appear to be and the inside of the driver wall pressed into my ears the whole time but it was otherwise comfy.
The new SHP9600’s just came out this week, and they’re definitely on my review-in-the-future list.
