1 3/8" wide x 2 1/4" high.I have worn both. I can only conclude Momentum's earpads were intentionally designed to be so small as they are significantly smaller than any other self-titled circumaural headphone. The UE6000 earpad is true circumaural size, similar to other circumaural headphones. I consider myself to have above average sized ears and the UE6000 is a great fit with even a little room. Also, the oval shape provides a much better seal and more comfort than fully round pads IMO.
