Headphoneus Supremus
I first listened without foams as did my husband. He then put foams on and said he liked them even more like that so I tried it too. Besides making the sound fuller they are more comfortable for me but I can see why some might like them without foams. Many people will not have foams at home.
You probably know that the Trig Rain store on aliexpress sells millions of colors of foams. They have to be stretched slowly and carefully or they can tear. I have mine in a little box I found at Wilkinsons... for a pound I think.
You've just put a smile on my face. That's a collection.
