I own the TteSports Thermaltake Shock Headset. And on the packaging, it states that the head cushion pad is leather, and I noticed on the rings of the ears, there is some kind of leather texture on that too.

Whatever kids are running this company, you've got to be more careful with that stuff. Label your products correctly on its advertisement, or trust me, you'll be facing consequences. I'm fed up of buying products which have no material listing, I end up getting an allergy, or am uncomfortable using them, and there's about £30 wasted on something I'm not going to use. Get yourselves together.
