Selling my Ultrasone HFI-2400 headphones. Ultrasone's top of the line, this model is now discontinued. Originally retailed for around $500. Currently there is only one pair of NOS on amazon for $229, Fleabay for $199 and $265. Forum price $125. For $50 more I will throw in an Audio Quest Dragonfly DAC.
Included are the two detachable cords and bag.
