Audioquest Dragonfly Cobalt vs. Chord Mojo vs. Dongles

A comparison between the Audioquest Dragonfly Cobalt, the Chord Mojo, and the Google / Apple Dongles. I was expecting an easy win for the Mojo, but it turned out much trickier: no one wins in all aspects, although the dongles are arguably much better value for money at what they deliver.

In short:
Dragonfly: Good for Soundtracks, EDM, Orchestra. Look out for sibilance especially paired with bright headphones.
Mojo: Good for Rock, Piano.
Vocals differ from singer to singer, even from track to track for some albums.

I partially agree with "No Theme Reviews" that the Dragonfly has a wider soundstage, better separation, feels bright and resolving.

However, I think the Mojo betters in the bass punch and texture, also piano tracks, especially the faster ones. "Flight from the City" by Jóhann Jóhannsson is a slow song where the Dragonfly's airy feel probably matters more than the Mojo's crispy key-stroke texture.
