I think the big difference with the other products avaible in market is that these ones (bigearinc) has a special solution to allow equalize the pressure!!

Hi, I´ve found out this ear plugs designed for skydivers, they has a patent that allows you equalize the presure. https://www.bigearinc.com/products/skydiving-earplugs-airplane-ear-plugs-big-ear/ They are expensive.... thinking if the are worth it!!! Anyone could give us some fedback??
