I have two older 20xls and a set of Zulus. I pulled all three out today getting ready for a flight tommorow and they are basically junk. They are sticky and not just the earmuf covering which i made the mistake of trying on and turned my face black the hole damn headset.Even the switch box is sticky. You can scratch impressions in it with your finger nail , its like goo.They were stored in their own bag inside my home on a shelf.anyone else experiance this.I thought at least the zulu was supposed to be decent but these are crap. as i right this my shirt and shorts are black now and my hands feel like they where rubbed down in glue.
