HiFiMan is a hard one to pin down. True, they’re best known for their high-end, advanced-technology planar-magnetic headphones like the $2,999 HE1000. Most HiFiMan headphones are planar designs, but this new one, Edition S, is a more conventional dynamic headphone, albeit one with a rather unusual feature: It’s an open- or closed-back design. Say what? Let me explain. Each earcup has a removable cover; with them in place, Edition S is a closed-back design, and since the covers are held in place by strong magnets, it takes just a few seconds to remove the covers, converting Edition S into an open-back design!
