This is a pair of Crystal Piccolino cables that I used with my JH Audio JH16's. The headphone cable is about 48" and works with JHAudio and Westone custom in ear monitors (maybe more brands too). The LOD cable is about 2" and is used to connect from iPod to portable amplifier. These cables were bought new from an individual who made them (not a company) in England 1 year ago. Thank you and let me know if you have any questions!
