USB D / A converter expressly dedicated to listening in headphones for PC or Mac computers. There will be no more audio contamination from the computer and your music both in headphones and through the Hi-Fi speakers, will sound in a way never heard before. Head Streamer does not need an external power supply, as it takes power directly from the mini USB input connector, regenerating it completely for all its internal circuits through proprietary components. Its connection is simple: you connect the USB cable (supplied) from the computer output to the entrance of the Header and using the Audio Class 1.0 drivers, present in any recent PC or Mac, it will not be necessary to waste time in long configurations. Then connect the 3.5mm jack plug of the Head Streamer, directly to the headphone cable or to the RCA input of the Hi-Fi system, using a 3.5mm mini-jack cable.
