Are those spigen ones still plastic on the inside? Like the material that touches the airpod max cups is plastic right? Just that the outside is lined with some fabric ish material?
It has a support material beneath the fabric. I don't know exactly if it is plastic or some other material, @tinyman392 may be able to tell you.
What I'd love to see, to follow the "bra" metaphor, is basically underwear for the earcups. Just a stretchable (and preferably elegant) fabric with the appropriate holes that you'd slip on the cups. Not to protect them against drops, but scratches / marks, while keeping the whole thing lightweight and slim.
I've been using these silicon ones mainly since the top portion is more open and convenient to interact with the buttons as opposed to other ones with cutouts https://www.amazon.com/gp/product/B08SJDZF3X/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
I have the Spigen transparent cups and my pet peeve with most transparent / silicone cups I've seen is how close to the microphones and vents the cover comes, and frequently the cutouts are improperly located, which I'm not sure is a good idea for a pair of headphones that relies so much on its microphones array and vents.
