How: Easy to use, just connect to the PC, then adjust the PC's bit depth and sample rate, done. I tried it with both the PC and my Samsung Galaxy S9, both worked very well. I hooked it up to a tube preamp and amp on my Elac Debut 2.0 6.2 and it sounded surprisingly good. This is a very good and cheap option for a DAC. Dislikes: It doesn't have its own power supply so it drains your phone, but there's no problem using it with a PC. I haven't tried the headphone jack, so I can't comment on that.
