I wish they could have achieved the same sound without this horrible glued piece of foam, such as with a passive filter. Or at least made it part of the earpads so that it can be replaced easily.
I mean for starters it makes the earpads feel more shallow which is not comfortable for people with big ears.
Secondly, sooner or later it will need to be replaced, especially since it can contact some people's ears. For example, Beyerdynamic puts in a new foam disk with a new set of earpads because the old one usuall wears off along with the old pads.
Look at all those classic vintage headphones, such as the AKG K1000, Sony R10 and some others. The deterioration of the foam is one of the main problems with them. And for such headphones as the Composer, you kind of expect for them to work flawlessly for years or even decades, probably also becoming classic some time.
Maybe they will get rid of it in the Composer V2 some day. It would be nice.
