The Jubilee 25 Edition headphones celebrate Ultrasone’s 25th year in business. The company will produce only 250 units of the $5999 closed-back headphones. The side panels are made from Macassar ebony with sterling silver inlays. The earpads, made from Ethiopian sheep leather, were wonderfully plush. On the headphone end, the cables terminate with Lemo connectors, a professional-style connector that locks firmly in place. The 40mm drivers are titanium-plated and mounted in a funnel-shaped baffle to place them farther from the listener’s ears.
