I have for sale a HiSoundAudio Studio that I recently purchased from another Head-Fi member who was the original owner.
It works perfectly and includes the USB/Charging cable but no headphones or box. The color is black with gold-colored buttons.
There is a very small nick in one of the polished edges on the top of the player which was there when I received it.
I have too many DAP's and mostly use my HM-602, so the Studio was purchased mostly out of curiosity.
SQ is very good and battery life unbelievably long.
Price includes domestic shipping and paypal fees.
