Oregon Aero Soft Seal Leather Ear Cushion.

More Info:

Oregon Aero has developed the SoftSeal Ear Cushions which have taken the headset world by storm.  Keep your ears even drier and cooler than with SoftSeal® Ear Cushions alone. Especially helpful in hot, humid climates.  They fit loose, not tight like a drum. (This is important because tight cloth covers produce pressure on the ear, causing pain.  These cushions are filled with memory foam which also allows you to comfortably wear sunglasses or prescription glasses without the pain or pressure. 

Compatible with standard cup size headsets. Not compatible with RRH17PEL/PEL2)
