What foam inserts are people running in Pyramid Z4’s on Astro?
 

Picked some of these up to try vs the usual suspects. They came without foams...

Any thoughts or comments on best way to proceed?

I’ve got some closed cell inserts which feel quite good inside but they look a little empty. Schu Tubby feel a bit big and are difficult to seat without bunching up.

I used schumacher in mine
