I don't currently have my pair in quite yet, however I had a simular issue with a previous pair of headphones, I placed a rolled up piece of tissue under the earpads from inside the pads around the circumference , I don't know if the sine pads have that pocket, but what they did on my other earphones was place the inside further away from my ear to prevent them touching.. Just a thought.

Hmmm.... I'll have to look into that.
If they do have a space, I'll probably use some of that non-slip rug pad material instead of tissue.
Thanks!
