Yes, the HP-3 really is a beautiful headphone. It’s almost got an industrial design aesthetic to it - what with the gimbals and the headband’s extendable sliders as well as the screws attaching them - but the leather and the wood also make it seem nicely handcrafted, almost artisanal. My preference is for the ebony version, as with @Lyer25’s lovely pair above.
The Massdrop Fostex TH-X00 Ebony is also quite attractive, even if it is nigh on impossible to photograph properly. I love how it seems to be inky black (this is my pair)…
… but that in the right light, you can also make out of the grain of the wood (stock photo from Drop)
