I have one, as well as a Geek Out V2. I prefer the Mojo by a small margin over the V2...I find it a bit warmer/less glare, with a blacker background. Overall a good SQ product in its price point, which is a departure for Chord. That said, I have a Geek Out 2a Signature Edition coming which I'll put up against the Mojo and expect to have the edge, especially balanced.I am listening via CA Andromeda, which are very sensitive to OI, so Mojo is a little dark, FWIW, but works very nicely for me. This thing has gobs of power, too...can drive HD650 if needed, but not fantastically. I have a set of HD650 coming soon, so I'll report back on the Mojo/GOV2/GO2aSE shootout with Balanced and SE cables for both ND650 and Andros, but it will be likely only in the new year.
Negatives - Mojo is a bit rolled in the treble and will suffer from RF interference from a phone - best to have some distance (no stacking) or use flight mode. Overall highly recommended, though.
