About us
Designed and tuned in our own studio
We started with one pair for a friend who mixed records at night. Today every model is still tuned by ear in the same small studio, built from metal, leather and glass to last for years.
Made to last
Metal, leather and glass
No soft plastics that crack in a year: aluminium, lambskin and sapphire glass, with every part you might wear out sold on its own.
