Sierra Aluminum (B-Stock)

Used or Refurbished Sierra Aluminum headphones available at a great price. 'B-Stock' items are Final Sale, and covered by our standard 2 year warranty. Sierra Aluminum is a Luxury take on the Sierra Reference commemorating the 5th year anniversary of the original Auribus project. This is our best headphone yet, 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. Please note, a powerful amplifier is required for these headphones to perform at their best! 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. Proudly Hand-Made in California! Made To Order
