Edit: should clarify I'm talking about apple dongle
Just went out and bought one of these. It sounds as transparent as I'd expect, and seems to pair well with my etymotic er4b. No weird upper mids harshness like with my shanling m0. Borrowing the USBC to USBA adapter from my hidizs dongle it works wonderfully with my computer as well, which is primarily what I bought it for.. Though for more dynamic tracks UAPP's volume scale is a bit too imprecise, since the dongle is *just* strong enough to really drive my er4b properly. Neutron solved that issue I suppose, though annoyingly it does not bind to the volume buttons properly. Can't have everything, I guess.
