Anything with temples- that is, all sunglassses- will increase the noise a little bit when used with any headset, any design. I have a friend who uses earplugs under Zulus because he wants the absolute best noise reduction he can possibly get. I use $20 Foster Grant Ironmans from Target, and I am a happy customer. Don't get too fussy about all these devices. All airplanes make noise and all headsets have problems of one kind or another- you are going to hear some noise no matter what you do.
