Portable DACs are inconvenient to use because they hang on a smartphone’s wire, and when in a pocket, they can just scratch its back and front surfaces. I wondered how to solve this problem.

User-unfriendly, poorly documented engineering marvel. Consider the following text as an attempt to write coherently about the ADC itself, as well as the process of using it. It’s sort of a loose (and certainly incomplete) user manual if you like.

This review matters for me a lot because it’s my first one of a kind: the very first review of a sound source that I would never have intended to write if it hadn’t been for Hidizs, which suddenly offered me to test their portable DAC.
