There isn't much for features or functions on this thing other than a balanced and unbalanced connection, but what it lacks in features, it more than makes up for in sound quality and build quality. Super small but very strong feeling and really nice secure ports.There is some kind of magic going on inside this thing and I think it's due to the current drive implementation they used that may be similar to Questyles take on the technology. All I know is that the sound is VERY dynamic and well separated with exceptionally good clarity and placement of sounds. I have never heard such good sound from such a compact package. This easily tops a lot of desktop gear I've heard costing well into the $500 range with IEMS, it really is that good.Thoroughly shocked by the sound quality of this thing. It gets a full recommendation from me.
