I've had the Pro Wireless for about 6 months and I'm quite happy with them - the headset fits comfortably but not too tight. They sit a little more snugly than the Razer Ultimate I had before but just right for me.

Only the ear pads I have exchanged for the cooling of WC Freeze because with the original ones the inside of the headphones was against my ear which was extremely uncomfortable after about 1 hour.

The WC Freeze ones are a bit thicker than the originals and since then they are perfect.

Hope that helps.
