These were commisioned by Astell Kern to run at 32 ohm instead of the standard 600 ohm of the T1 so that these superb headphones could run on low powered amps or on a DAP like ones that Astell Kern make. These are in great condition without any flaws or apparent wear. No smoking homes of which I am the second owner. I' listen now-a-days to the Beyerdynamic T1 version 3 which are also 32 ohms.
Included are 4 cables. Two by Astell Kern of which one has a 2.5 mm input and one of a more common 3.5 input. These are bother a meter long. In addition, two after market cables with 3.5 input, one of 10 ft and one of 3 ft. Also adapters for 1/4 inch headphone jacks and an other adapter to convert from 2.5 to 3.5. I never used these headphone roaming about, only at home.
Also orginal box with carrying case.
