These went out of production several years ago, but whatever. First, the earpads are made from an awful stiff leathery plastic material that is uncomfortable and doesn't seal whatsoever, feels like hard plastic on your ears. Sound is kind of muffled, echoey, mids pushed forward, lacks bass (as someone mentioned, it rather feels like some unnatural bloated bass, and even so it's not prominent) they are closed but it lets a lot of sound in, even with different earpads. Onto that, I did replace the earpads so fit, comfort and isolation improved...
