Aroma Audio is a Hong Kong company that produces iems, dac and amps. For iems, they started out with the Witch Girl series which has a line-up that consists of the Witch Girl S, Witch Girl Pro and Witch Girl 12. Earlier this year, they have launched a brand new series which is called Musical Box. In the Musical Box Series, there are the Early, Twins and Yao. This year, they release their flagship in the Ace. I would like to thank Aroma Audio for the review unit of Ace. More information can be found on Aroma and their Facebook .
