Mad Catz F.R.E.Q. DAC Digital-to-Analog Audio Converter with Touch Panel for Volume Control- USB Type-C to 3.5 mm

It's a small convenient package.The pictures make it look a lot larger than it is actually. It's a smidgen bigger than the Dawn Pro and Fosi DS1.Sound quality is good. The options of a 1 button EQ for music, movies, FPS, or no EQ is a nice bonus. The button changes colors depending on what is selected.The music adds a nice bassier and fun curve signature.The volume touch slider is a nice bonus. It works in tandem and not independently of the phones volume.For under $17, this is a real winner.The only cons:Non detachable cable.Only 3.5mm recessed cable connection.

The touch volume control for this device is TOO sensitive. I triggered it accidentally too many times.Also the headphone jack port is faulty; if I plug it in all the way, snuggly, the sound doesn't output evenly on both drivers. It has to fit a bit loosely in order for sound to come out clearly - but not too loosely, otherwise sound drops & it slips out.
