Compared to S9, the sound is softer, musical, but at the same time the detailing is excellent.
It is really beautiful even thou I wanted the one with the pretty Hidizs logo , nice built . It has a great output power , works good with my Samsung A20 and Xiomi redminote 9 pro ,I've been using it whit my BQEYZ spring 2 , Blon 03 , Kb ear lark and Urbanfun and listening to my Flac and MQA playlist . Improves the soundtage , the mids and elevate the highs( with urbanfun was a little big harsh ) , good bass improvement too . Better sound and tonality . But there is a big problem , it overheats so much .
