You can use a headset that uses earplugs instead of domes. Clarity Aloft, Auricomm, and Lightspeed all manufacture these models. I have tried them all, and put the Lightspeed at the bottom of the list, with the other two pretty close together. They're comfortable, and have higher noise reduction numbers than domed headsets, even ANR/ENC models. They can also be worn with standard baseball caps, without removing the button on top. I'll never go back to heavy domed headsets.
