PROZOR 192KHz Optical Digital to Analog Converter DAC with 3.5mm Mini Jack, Compatible with PS4, XBox, HD DVD, etc. Please refrain from purchasing if you are looking for a pristine item, as this has been stored by a private individual. Please examine the images carefully before considering a purchase. I used this for approximately two years to connect the optical digital output of my TV to 3.5mm speakers, but I am selling it because I upgraded to a model with a volume control knob. I used it to watch music programs and movies. A 3.5mm cable will be included as a bonus. Although it is not the original box, it will be shipped in a box via Yu-Packet Post Mini. #OpticalDigital #AnalogConversion #3.5mm
