These are modern foam ears for JT Proflex. This new style of soft ears comes with a metal-reinforced center and lower hole so they won't rip as easily. The lower hole allows you to attach them in 2 spots to your JT Proflex, unlike traditional soft ears that only have one hole location.
These are custom-made by DoCoolShit and exclusively on PBretro.com
I have some in stock now so don't miss out!
