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. Recently, they have launched a brand new series which is called Musical Box. In the Musical Box Series, there are the Early, Twins and Yao. In this review, I will be reviewing the Musical Box Twins. I would like to thank Aroma Audio for this review unit. At the moment, you can get it from Aroma.
