The product itself is great overall value for money as a replacement part.
I have a Razer Kraken Kitty V2 BT, and as seen in photos, the head cushion replacement is just a little short of the full length of the arch.
Foam is a bit denser than the original padding, so the faux leather feels a tiny bit tougher. The original leather feels smoother, but likely due to 3½ years of wear and tear.
Comes in small unprotected packaging.
