The Ultrasone edition 10 are beautiful headphones. They also cost almost $3,000. From Ultrasone:
“The outer ear cup is finished with galvanic Ruthenium plating and with a Zebrano wood inlay, which is coated with eight layers of clear lacquer for protection. The Edition 10′s inner ear cup, as well as the head-pad, is adorned with reddish brown Ethiopian sheepskin. This type of leather is known for being the most supple leather available, achieving the maximum level of comfort and sound isolation.”
