What is the difference specifically between the premium memory foam and the sheepskin? Just the softness of the leather? I bought the premium ones before and they were honestly quite soft indeed. Also for those interested to know, i bought the Standard velour pads when they dropped last month and was a little disappointed at the difference in sound. The comfort is quite nice but dont really like the change in sound. Not sure if the Elite Velour will change the sound the way the normal velour did.
