Everyone knows that Muramasa was the most famous swordsmith in feudal Japan. Before his death, he forged not a sword, but a magical pair of headphones that would bestow upon its wearer eternal life…no, no that’s not true at all. For $8,000, the Muramasa VIII by Final Audio Design might as well be an enchanted artifact. The Muramasa VIII headphones instead bestows upon its wearer 1.8 pounds of aural stimulation, including a tweeter and driver in each ear for two-way capability. Just like your mom.
