New in the forum. I want to ask if someone had anytime put foam inside a pair of cup/headphones to allow better isolating noise. Experiences? could that improve sound?
It's likely to make the sound worse especially if it's open back, since that will block what is supposed to be a free-air mount and the driver won't be able to breathe properly, and yet isn't completely sealed either. Some closed headphones can benefit as it dampens the cups, either by mass loading, absorbing or slowing down the backwaves that would otherwise bounce off the closed cup with too much energy, or changing the volume of the enclosure (that might tighten up the bass), or any combination of these.
thanks for answers. I was mainly thinking in trying to isolated more a over the ear, close headphones, putting some kind of material on the "circel wall" that make the oval. I dont think it should be difficult, and also maybe reversible. The problem is that it is not easy to find a so small isolating material.
