Easy wireless connection between computer and dac - CD quality listening. No compressed loosy Bluetooth > Just plug dongle in to the USB and choose wireless on the DAC. Rdac will  automaticly pair with computer using wireless dongle..You dont need to use existing  wifi at home. It will create own wifi conection. . And what is nice there is no latency at all. ,Good for watching movies and gaming  streaming from comp to DAC with cd loosless quality...Important is computer audio settings must be set up to CD 44.1khz. No DVD 48 Khz. Otherwise sound will be enerupted, DAC of course support 48khz too, but not over the wifi. It is very good  sounded DAC better with coaxial or USB connection.,Very musical full body 3dimensional sound .Better even with linear power supply which i am using with my second DAC im keeping..
