California Headphones has created an innovative set of metal and leather headphones acoustically tuned to deliver the best live concert audio experience. Featuring a retro design inspired by the aviation styles of World War II, the Laredo and Silverado boast an impressive list of unique features. The Laredo is a premium on-ear headphone constructed with stamped metal and leather featuring 40mm drivers while the Silverado is an over-the-ear, foldable headphone made with die-cast metal and leather materials with the same 40mm drivers. Both headphones use metal sound chambers with titanium drivers to create a rich, highly-focused sound that makes vocals, guitars and drums heightened and clear, enabling you to listen in its purest form. These are slated for release in August, with the Laredo retailing at $99.95 USD and the Silverado at $225.95 USD.
