This is our best headphone ever, now with a warmer, more refined tuning paired with a premium Solid Aluminum cup and headband. The advanced SLM Metal 3D Printing and polishing process create a unique raw finish unlike any other headphones, all while keeping weight to a minimum. 

We've come a long way since the beginning in 2019. Thank you for coming along in this journey, as we continue to work at perfecting a new class of headphones.
