I have some closed-back headphones that have poor sound. Is it possible to improve the sound of the headphones by installing additional speakers?
How much better can the sound of the headphones be if the cups are covered with soundproofing tape?

These are Chinese headphones with no name. However, they looked impressive and I was foolish enough to buy them instead of the inexpensive Sennheiser headphones which cost about the same.
